I am trying to do an application with Xamarin.android. It is "ToDoList" and I have two tabs, one of them is to create and edit the chores(it is called "undone"). The other one is for the chores that are marked as done(it is called done). I have used Fragments for the tabs and what I am trying to accomplish is when I mark one task as done I want to delete it from the list in the "undone" tab and add one to the list in "done" tab.
MainActivity.cs
public class MainActivity : Activity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.activity_main);
this.ActionBar.NavigationMode = ActionBarNavigationMode.Tabs;
var tab1 = ActionBar.NewTab();
tab1.SetText("Undone");
var tabFirst = new UndoneListFragment();
tab1.TabSelected += (sender, e) =>
{
var fragment = this.FragmentManager.FindFragmentById(Resource.Id.tabsContainer);
if (fragment != null)
e.FragmentTransaction.Remove(fragment);
e.FragmentTransaction.Add(Resource.Id.tabsContainer, tabFirst);
};
tab1.TabUnselected += (sender, e) =>
{
e.FragmentTransaction.Remove(tabFirst);
};
var tab2 = ActionBar.NewTab();
tab2.SetText("Done");
var tabSecond = new DoneListFragment();
tab2.TabSelected += (sender, e) =>
{
var fragment = this.FragmentManager.FindFragmentById(Resource.Id.tabsContainer);
if (fragment != null)
e.FragmentTransaction.Remove(fragment);
e.FragmentTransaction.Add(Resource.Id.tabsContainer, tabSecond);
};
tab2.TabUnselected += (sender, e) =>
{
e.FragmentTransaction.Remove(tabSecond);
};
ActionBar.AddTab(tab1);
ActionBar.AddTab(tab2);
}
}
UndoneListFragment.cs
public class UndoneListFragment : Fragment
{
List<Task> tasks = new List<Task>();
ListView lView;
TasksViewAdapter adapter;
View view;
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
// Use this to return your custom view for this Fragment
// return inflater.Inflate(Resource.Layout.YourFragment, container, false);
base.OnCreateView(inflater, container, savedInstanceState);
view = inflater.Inflate(Resource.Layout.undoneListView, container, false);
Button addBtn = view.FindViewById<Button>(Resource.Id.AddBtn);
lView = view.FindViewById<ListView>(Resource.Id.TasksViewList);
adapter = new TasksViewAdapter(view.Context, tasks);
lView.Adapter = adapter;
lView.ItemClick += Edit;
addBtn.Click += AddTask;
return view;
}
}
public override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
base.OnActivityResult(requestCode, resultCode, data);
switch (requestCode)
{
case 10:
if (resultCode == Result.Ok) //Edit an already existing task
{
var replacedTaskName = data.GetStringExtra("new_name" ?? "Name not found");
var position = data.GetIntExtra("listPos", 0);
bool done = data.GetBooleanExtra("done", false);
Task t = new Task(replacedTaskName);
if (done == true)
{
t.TaskStatus = Status.Done;
//here I want to implement the code to somehow
//send the replacesTaskName to the second fragment
//Your suggestion is here
DoneListFragment frag = new DoneListFragment();
Bundle b = new Bundle();
b.PutString("MyKey",replacedTaskName);
frag.Arguments = b;
}
tasks[position] = t;
adapter.NotifyDataSetChanged();
string newName = tasks[position].TaskName;
break;
}
}
}
DoneListFragment.cs
public class DoneListFragment : Fragment
{
List<Task> doneTasks = new List<Task>();
ListView lView;
TasksViewAdapter adapter;
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
base.OnCreateView(inflater, container, savedInstanceState);
var view = inflater.Inflate(Resource.Layout.doneListView, container, false);
Button deleteBtn = view.FindViewById<Button>(Resource.Id.DeleteAllBtn);
lView = view.FindViewById<ListView>(Resource.Id.doneList);
adapter = new TasksViewAdapter(view.Context, doneTasks);
lView.Adapter = adapter;
if(Arguments != null)
{
string value= Arguments.GetString("MyKey");
}
//click to delete done tasks
deleteBtn.Click += DeleteAll;
return view;
}
}
For Sending data from one fragment another one simple step is creating constructor while replacing
the fragment or calling fragment.
For Example:
Suppose I have two fragments ,
ActionFragment
ActionDetailsFragment
Now I want to send data from “ActionFragment” to “ActionDetailsFragment”:
In ActionFragment :
fragmentManager = getChildFragmentManager();
fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.frameLayoutActionDetails, new ActionDetailsFragment(Data x, Data y)).commitAllowingStateLoss( );
Now below code will be in “ActionDetailsFragment”
public class ActionDetailsFragment extends AppFragment {
Data x;
Data y;
public ActionDetailsFragment(Data x, Data y) {
super();
this.x = x;
this.y = y;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
—————————————
////———Here is your code———————
—————————————————
}
Now you can use “Data x, Data y” in ActionDetailsFragment…
Thats it…
Note: Data x and Data y both are imaginary variables..
Activity’s cannot use in TabLayout or ViewPager you must have to use Fragments .
You can use “Bundle” instead,
Fragment fragment = new Fragment();
Bundle bundle = new Bundle();
bundle.putInt(key, value);
fragment.setArguments(bundle);
Then in your Fragment, retrieve the data (e.g. in onCreate() method) with:
Bundle bundle = this.getArguments();
if (bundle != null) {
int myInt = bundle.getInt(key, defaultValue);
}
Well if you are looking for Fragment to Fragment data transfer the smart way of doing it would be using fragment arguments, Something like this:
When you initialize the fragment object in your case:
var frag= new DoneListFragment();
Bundle bundle= new Bundle();
bundle.PutString("YourKey", "YourValue");
frag.Arguments=bundle;
Then to retrieve this data you do something like this in DoneListFragment in the OnCreateView method:
if(Arguments!=null)
{
String value = Arguments.GetString("YourKey");
}

I am new in android, especially in Xamarin Android C#. I have bottom navigation tabs and fragments. They are fragment_picture (tab_picture), fragment home (tab_home), fragment notifications (tab_notifications), fragment_profile (tab_profile). Inside fragment_picture (tab_picture), I have 2 tabs. They are fragment_camera(tab_camera), and fragment_gallery(tab_gallery). I want to move the tabs of fragment_picture such as when I click the tab_camera, it shows the XML of the tab_camera and when I click the tab_gallery, It shows the XML of the tab_gallery.
I don't use viewpager. I am just using fragments. The tab won't change the position to its XML. I've searched a lot in Google But, I still confused. Please help me
using System;
using Android.OS;
using Android.Support.Design.Widget;
using Android.Views;
using Android.Support.V4.App;
using Android.Widget;
namespace MyPhotographicMemory.Droid.Fragments
{
public class Fragment_Picture : Fragment
{
TabLayout tabLayout;
private TabLayout.Tab tabGallery, tabCamera;
Fragment fragment = null;
public override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
}
public static Fragment_Picture NewInstance()
{
var frag2 = new Fragment_Picture { Arguments = new Bundle() };
return frag2;
}
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var ignored = base.OnCreateView(inflater, container, savedInstanceState);
var v = inflater.Inflate(Resource.Layout.FragmentPicture, null);
tabLayout = v.FindViewById<TabLayout>(Resource.Id.pictureTabLayout);
tabLayout.TabSelected += (object sender, TabLayout.TabSelectedEventArgs e) =>
{
switch (e.Tab.Position)
{
case Resource.Layout.FragmentCamera: //Resource.Id.tabItem1
fragment = new Fragment_Camera();
TabLayout.Tab tab = tabLayout.GetTabAt(0);
tab.Select();
break;
case Resource.Layout.FragmentGallery: //Resource.Id.tabItem1
fragment = new Fragment_Gallery();
TabLayout.Tab tab1 = tabLayout.GetTabAt(1);
tab1.Select();
break;
}
};
return v;
}
}
}
Do you want to achieve the result like this GIF?
If so, you should achieve the nested tabs with fragment.
Here is my code when in my first fragment.
public class Fragment1 : Fragment
{
public override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your fragment here
}
public static Fragment1 NewInstance()
{
var frag1 = new Fragment1 { Arguments = new Bundle() };
return frag1;
}
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var ignored = base.OnCreateView(inflater, container, savedInstanceState);
var view = inflater.Inflate(Resource.Layout.fragment1, null);
BottomNavigationView bottomNavigationView= view.FindViewById<BottomNavigationView>(Resource.Id.mynested_bottom_navi);
bottomNavigationView.NavigationItemSelected += BottomNavigationView_NavigationItemSelected;
LoadFragment(Resource.Id.tab_camera);
return view;
}
private void BottomNavigationView_NavigationItemSelected(object sender, BottomNavigationView.NavigationItemSelectedEventArgs e)
{
LoadFragment(e.Item.ItemId);
}
//switch fragment by tab id.
void LoadFragment(int id)
{
Fragment fragment = null;
switch (id)
{
case Resource.Id.tab_gallery:
fragment = Fragment_Gallery.NewInstance();
break;
case Resource.Id.tab_camera:
fragment = Fragment_Camera.NewInstance();
break;
}
if (fragment == null)
return;
FragmentManager.BeginTransaction()
.Replace(Resource.Id.mynest_content_frame, fragment)
.Commit();
}
}
Here is my demo, you can refer to it.

I am very new to Xamarin so i don't have the clearest idea on how inflators work.
How can i add functionality to a page that uses inflators to scroll between tabs? I.E. Where do i put the code for a button click event, when the button can be found in
var root = inflater.Inflate(Resource.Layout.Fragment, container, false); ?
This is my fragment page:
namespace OfficialApp{
public class ContentFragment: Fragment{
private int position;
public static ContentFragment NewInstance(int position)
{
var f = new ContentFragment();
var b = new Bundle();
b.PutInt("position", position);
f.Arguments = b;
return f;
}
public override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
position = Arguments.GetInt("position");
}
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var root = inflater.Inflate(Resource.Layout.Fragment, container, false);
var editFile = inflater.Inflate(Resource.Layout.editFile, container, false);
if (position == 0)
{
return root;
}
else if (position == 1)
{
return editFile;
}
else
ViewCompat.SetElevation(root, 50);
return root ;
}
}
}
Sorry if this is a vague or silly question but i honestly have not been able to find the answer anywhere.
What i'm not sure about is how to give each fragment its own activity so that for example pushing a button runs an on click event.
To find a control in the view which is inflated by var root = inflater.Inflate(Resource.Layout.Fragment, container, false);, you can code for example like this:
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var view = inflater.Inflate(Resource.Layout.fragment1, container, false);
var btn = view.FindViewById<Button>(Resource.Id.btn);
return view;
}
I'm trying to create an activity with two tabs, one holding FragmentA and one holding FragmentB. Here is how I add the fragments to the Activity:
[Activity(Label = "My App")]
public class MyActivity : Activity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.ConnectionMenu);
ActionBar.NavigationMode = ActionBarNavigationMode.Tabs;
AddTab("A", new FragmentA());
AddTab("B", new FragmentB());
}
private void AddTab(string tabText, Fragment fragment)
{
var tab = ActionBar.NewTab();
tab.SetText(tabText);
tab.TabSelected += (sender, e) =>
{
e.FragmentTransaction.Replace(
Resource.Id.fragmentContainer,
fragment);
};
ActionBar.AddTab(tab);
}
}
When I rotate the orientation I want to keep fields filled out in the fragments the same. I save my data in OnSaveInstanceState and restore the data in OnActivityCreated. However, I'm noticing that the OnCreateView and OnActivityCreated methods are being called twice per rotate. The first time containing my filled in Bundle and the second time with bundle being null.
I assume that my error is in the MyActivity class but if you need more information let me know!
Given you create the fragment in your Activity.OnCreate(), you will always have 2 calls due to creating new ones in the method, and maintaining the old ones in the base.OnCreate(). What you should probably do is instead of always creating these fragments, you can search via a tag or ID for an existing fragment and use those in the Tabs instead.
i.e.
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.ConnectionMenu);
ActionBar.NavigationMode = ActionBarNavigationMode.Tabs;
if(savedInstanceState == null)
{
AddTab("A", new FragmentA());
AddTab("B", new FragmentB());
}
else
{
Fragment a = (FragmentA)SupportFragmentManager.FindFragmentByTag("my_tag_a");
Fragment b = (FragmentB)SupportFragmentManager.FindFragmentByTag("my_tag_b");
AddTab("A", a);
AddTab("B", b);
}
}
I ended up solving the issue. as #JonDouglas said you need to make sure the tab wasn't already loaded before creating a new fragment. To do this the fragment can be loaded from the FragmentManager class using a tag. During the TabSelected event if the fragment was not previously create, a new fragment is created and added to the event FragmentTransaction using the tag. During the TabUnselected event, if the fragment was created then it is detached.
I also added in a Bundle value to hold onto the last active tab.
Here is the code I used to solve the issue.
[Activity(Label = "My App")]
public class MyActivity : Activity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.ConnectionMenu);
ActionBar.NavigationMode = ActionBarNavigationMode.Tabs;
AddTab("A", "a_fragment", () => new FragmentA());
AddTab("B", "b_fragment", () => new FragmentB());
if (savedInstanceState != null)
{
var selectedTab = savedInstanceState.GetInt(
"ActionBar.SelectedNavigationIndex", 0);
ActionBar.SetSelectedNavigationItem(selectedTab);
}
}
protected override void OnSaveInstanceState(Bundle savedInstanceState)
{
base.OnSaveInstanceState(savedInstanceState);
savedInstanceState.PutInt(
"ActionBar.SelectedNavigationIndex",
ActionBar.SelectedNavigationIndex);
}
private void AddTab<TFragment>(
string tabText,
string tag,
Func<TFragment> ctor) where TFragment : Fragment
{
var tab = ActionBar.NewTab();
tab.SetText(tabText);
tab.SetTag(tag);
var fragment = FragmentManager.FindFragmentByTag<TFragment>(tag);
tab.TabSelected += (sender, e) =>
{
if (fragment == null)
{
fragment = ctor.Invoke();
e.FragmentTransaction.Add(
Resource.Id.fragmentContainer,
fragment,
tag);
}
else
{
e.FragmentTransaction.Attach(fragment);
}
};
tab.TabUnselected += (sender, e) =>
{
if (fragment != null)
{
e.FragmentTransaction.Detach(fragment);
}
};
ActionBar.AddTab(tab);
}
}
I have two tabs in viewpager. So in fragment1 I input a text and when in tab2 is selected and then fragment2 will get data from that text from fragment1.
ex: when I open tab1 -> I input a text is "abcd" -> I open tab2 -> I want to get a text is "abcd" from tab1(fragment1).
public class Fragment1 : Android.Support.V4.App.Fragment
{
Fragment2 frag2 = new Fragment2();
public override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your fragment here
}
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
// Use this to return your custom view for this Fragment
// return inflater.Inflate(Resource.Layout.YourFragment, container, false);
Singleton singleton = Singleton.GetInstance();;
singleton.SetSource("abcd");
}
}public class Singleton
{
private static Singleton singleton;
string a = null;
private Singleton()
{
}
public static Singleton GetInstance()
{
if (singleton == null)
singleton = new Singleton();
return singleton;
}
public void SetSource(string text)
{
this.a = text;
}
public string showMessage()
{
return a;
}
}
public class Fragment2 : Android.Support.V4.App.Fragment
{
public List<string> data = new List<string>();
public void add(string t)
{
data.Add(t);
}
TextView txt;
public override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your fragment here
}
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
// Use this to return your custom view for this Fragment
// return inflater.Inflate(Resource.Layout.YourFragment, container, false);
//return base.OnCreateView(inflater, container, savedInstanceState);
return inflater.Inflate(Resource.Layout.view2, container, false);
txt = View.FindViewById<TextView>(Resource.Id.txtgetdata);
if (data != null)
{
txt.Text = data[0];
}
else
Toast.MakeText(Application.Context, "no", ToastLength.Long).Show();
}
}
I have tried it but don't having the result.
After a few hours of research/test & debugging and solved, try this out.
In your Activity
add public string tabFragment { get; set; }
In your source fragment
ie on click or that navigate to other fragment
string tab = ((ActivityUser)Activity).tabFragmentAddUser;
FragmentAddUser fragment = (FragmentAddUser);
Activity.SupportFragmentManager.FindFragmentByTag(tab);
fragment.setValText("Hello");
viewPager.SetCurrentItem(1, true);
In your destination fragment (ie which elements will be modified)
add a method like this
public void setValText(string str) { txtUsrFirstName.Text = str; }
==================================================================
Fragment fragment = new Fragment();
Bundle bundle = new Bundle();
bundle.putInt(key, value);
fragment.SetArguments(bundle);
in on create of the other fragment
Bundle bundle = this.GetArguments();
int myInt = bundle.GetInt(key, defaultValue);
optionaly two fragments should never communicate directly and should communicate through activity
From Developers website:
Often you will want one Fragment to communicate with another, for
example to change the content based on a user event. All
Fragment-to-Fragment communication is done through the associated
Activity. Two Fragments should never communicate directly.
refer this and this
Here is the bit of code I have so far :
namespace MyTestApp2
{
[Activity(Label = "Simple ListView", MainLauncher = true, Icon = "#drawable/icon")]
public class Activity1 : FragmentActivity {
private CustomViewPager _viewPager;
string[] items;
protected override void OnCreate(Bundle bundle) {
base.OnCreate(bundle);
SetContentView(Resource.Layout.Main);
//items = new string[] { "Jon Douglas", "Jax The Cat", "Moxxi The Cat", "Andie The Dog" };
//ListAdapter = new ArrayAdapter(this, Android.Resource.Layout.SimpleListItem1, items);
_viewPager = FindViewById<CustomViewPager>(Resource.Id.ViewPager);
_viewPager.Adapter = new MyFragmentAdapter(SupportFragmentManager);
}
//protected override void OnListItemClick(ListView l, View v, int position, long id)
//{
// var t = items[position];
// Toast.MakeText(this, t, Android.Widget.ToastLength.Short).Show();
//}
}
public class MyFragmentAdapter : FragmentPagerAdapter
{
public MyFragmentAdapter(Android.Support.V4.App.FragmentManager fm) : base(fm)
{}
public override int Count
{
get {
return 5; }
}
public override Android.Support.V4.App.Fragment GetItem(int position)
{
//List<Android.Support.V4.App.Fragment> test = new List<Android.Support.V4.App.Fragment>();
//test.Add(new MyFragment());
//test.Add(new MyFragment2());
if (position == 0)
return new MyFragment();
else
return new MyFragment2();
//return test[position] == null ? new MyFragment() : test[position];
}
public override void SetPrimaryItem(View container, int position, Java.Lang.Object #object)
{
base.SetPrimaryItem(container, position, #object);
}
}
public class MyFragment : Android.Support.V4.App.Fragment
{
string[] animals = new string[5] { "Tiger", "Lion", "Zebra", "Cheetah", "Giraffe" };
Context thiscontext;
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var view = inflater.Inflate(Resource.Layout.MyLayout, container, false);
var test = view.FindViewById<ListView>(Resource.Id.listView1);
thiscontext = container.Context;
test.Adapter = new ArrayAdapter(Activity, Android.Resource.Layout.SimpleListItem1, animals);
test.ItemClick += OnListItemClick;
return view;
// return base.OnCreateView(inflater, container, savedInstanceState);
}
void OnListItemClick(object sender, AdapterView.ItemClickEventArgs e)

}
}
public class MyFragment2 : Android.Support.V4.App.Fragment
{
private string[] animals = new string[5] { "Mackeral", "Sea Lion", "Dolphins", "Sardine", "Whales" };
Context thiscontext;
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{

// return base.OnCreateView(inflater, container, savedInstanceState);
}
void OnListItemClick(object sender, AdapterView.ItemClickEventArgs e)
{

}
}
public class CustomViewPager : ViewPager
{
private bool enabled;
public CustomViewPager(Context context, Android.Util.IAttributeSet attr) : base(context, attr) { this.enabled = true; }
public override bool OnTouchEvent(MotionEvent e)
{
if(this.enabled)

return base.OnInterceptHoverEvent(e);
return false;
}
public override void SetCurrentItem(int item, bool smoothScroll)
{
base.SetCurrentItem(item, smoothScroll);
}
}
}
As you can see from the above, i have attempted to add code to the OnListItemClick event, however, ive not succeeded in changing the fragment.
So, I need the code to do the following :
Not to change pages when swiping left or right
but only change pages by clicking a list item
Am I going in the right direction ?
I was able to resolve my issue by doing the following :
Changing my Fragment class to a ListFragment class
Setting my ViewPager as a property
Using the ViewPager property to setCurrentItem to the next ListFragment class
Code :
public class MyFragment : Android.Support.V4.App.ListFragment
{
string[] animals = new string[5] { "Tiger", "Lion", "Zebra", "Cheetah", "Giraffe" };
CustomViewPager vpager;
Context thiscontext;
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
thiscontext = container.Context;
var view = inflater.Inflate(Resource.Layout.Main, container, true);
var vp = view.FindViewById<CustomViewPager>(Resource.Id.ViewPager);
vpager = vp;
return base.OnCreateView(inflater, container, savedInstanceState);
}
public override void OnActivityCreated(Bundle savedInstanceState)
{
base.OnActivityCreated(savedInstanceState);
this.ListAdapter = new ArrayAdapter<string>(Activity, Android.Resource.Layout.SimpleExpandableListItem1, animals);
}
public override void OnListItemClick(ListView l, View v, int position, long id)
{
// We can display everything in place with fragments.
// Have the list highlight this item and show the data.
ListView.SetItemChecked(position, true);
// vpager.SetOnPageChangeListener(new PagerListener());
vpager.SetCurrentItem(1, true);
}
}
This took a few hours to resolve and may help others.
