FindViewByID() Can't find my ID (2 activities)

I am new to Android programming and I have a little issue.
So I have 2 Activities and 2 layouts.
The problem is that I have a button in my second activity and when I try to declare it FindViewById() can't find the id from the second layout. I re-built the app and I double checked the IDs - they match but simply the function FindViewById() does not find my button's id.
Example:
I have a button in my second layout(second activity? i don't know what is correct to say, as I said im new to android programming)
The button ID is = LoginButton, When I go to my second activity and type
Button LoginButton FindViewByID(Resources.Id.LoginButton);
The function does not find it :/
Im so confused. Please help me

This is because the Resource.Designer can not be created successfully and that is because you have errors in your Layout, so always be aware to check if all properties are defined good.
In MenuList.axml:
Change android:textColor="000" to android:textColor="#000" (most likely this is the problem)
android:layout_height="210.5dp" do you really need those .5 dp? I suggest to put it to android:layout_height="210dp"
Remove android:layout_marginBottom="0.0dp" the margin is anyway 0dp.
After doing this changes Clean and Rebuild the project and see if the error disappear.
To track this kind of errors put your Build in diagnostic so you can
see what is making a problem.

Have you declared the button in the XML file of the second activity? If you have only declared it in the first activity, then findviewbyid won't show an error since there exists an element with that ID. But it won't run (will throw an error) simply because it won't be able to locate that specific element in your (second) activity.

Check if your button's ID is named "#+id/LoginButton"
The correct spelling should be findViewById(R.id.LoginButton) not the way you typed in your question.
Or Are you trying to get the View out of a Fragment?
Try getView().findViewById(...);
if that not works, give us some code, sounds like a typo somewhere.

Ranorex test automation issue: Unable to reliably click a button on silverlight web app

We have automated a few test cases using the Ranorex automation framework for a Silverlight web application. These test cases involve clicking buttons in order to invoke certain messages on the screen. In order to grab the button on the screen, we first create an Ranorex button object and then point it to the appropriate element using Ranorexpath. Then, we use the RanorexButton.Click() event to click the button. However, this event is unreliable. It works sometimes and at other times the button is not clicked. When the button is not clicked, we have to run the test case again from the start. What are we doing wrong? If this is a known problem of ranorex, please suggest workarounds.

I was facing the same problem but I am able to resolve the problem by introducing a Validate.Exists(infoObject) just before the click. Please make sure that you pass infoObject of your button or any element in Validate.Exists API.
Example:
Validate.Exists(repo.MyApp.LoginBtnInfo);
var button = repo.MyApp.LoginBtn;
button.Click();
With regards,

I haven't heard about such a problem with Ranorex yet, maybe this is just a timing issue.
You could add a Validate.Exists(yourButton) right before the click, this ensures that the click is performed after the button was successfully loaded.
If it is a WebElement you could also use the PerformClick() method instead of the normal Click() method.
There are also different methods which will ensure that the button is in the visible area and has focus, like the EnsureVisible() or the Focus() method.
You will find the available methods of the used adapter in the online API of Ranorex.

If the Button is not within the area you can see without scrolling, you can use a
var button = repo.Buttons.button1;
button.EnsureVisible();
button.Click();
In this way the button is forced to be watched.

It might as well be an issue with the xpath and element Id-s.
If you have changing element Id-s even when the page is navigated away from and moved back (for example we have this issue with SAP related components) you might need to make a more robust xPath path variable using regular expressions.
Try to find object and parts of the path that do not change (eg. "iFrame id="MainContent"" or "btn id="ID_XXXX_Search_Button"") - ofcourse this will only help if the issue is within this.
Ranorex Regular Expression info can be found here: http://www.ranorex.com/support/user-guide-20/ranorexpath.html#c3294
A quick example of what I'm talking about:
Let's say we have an input field that has a changing ID in it's name:
US_EL.ID_F2B49DB60EE1B68131BD662A21B3432B:V_MAIN._046A-r
And I know that the part in the Id that doesn't change is:
:V_MAIN._046A-r
I can create a path for this searching the element by the ending of the elements' id that doesn't change using regular expression:
/dom[#domain='test.example.com']//iframe[#'identifier']//iframe[#'identifier2']//input[#id**~'^**:V_MAIN._046A-r']
The bold part will specify to search for an input element with an Id that ends with ":V_MAIN._046A-r".
An issue that might arrise from this is if you have elements using partially the same names you might get multiple elements returned for the same path. So it's wise to add a few more certain points to the path (eg. "iframe[#'identifier2']") when this issue arrises.

Open a new window using MapAreaAttributes in microsoft chart control

i am using MS asp.net 3.5 chart control (Pyramid) and on the click of the series/datapoint i need to open a URL in a new window, something like javascript window.open.
Now i have tried a hell lot but that doesn't work. I am not able to give javascript to the datapoint.
Secondly i got to know that MapAreaAttributes could be given to Series as mentioned below if a new window needs to be open
series.MapAreaAttributes= "target='_blank'";
But even this doesn't works????
Guide me! Thanks

I had your same problem just now.
Here is the solutions and it works:
Notice in your code that you're using the single quotation ('). It seems that this is not allowed by the chart control or something. Let me give you an example that might help you understand:
Let's assume you have a JavaScript function that opens a window showing some data when the user clicks on a column (point) in your data (series). You can do it like this:
Chart1.Series["MySeries"].Points[0].Url = "javascript:void(0)"; //this is just to tell the browser not follow a URL, since you will control this with your javascript
Chart1.Series["MySeries"].Points[0].MapAreaAttributes = "onclick=\"OpenWindow();\""; //this is to set the onclick attribute to fire your javascript function when the user clicks your column.
In the above example in the second line of code, notice that I have used double quotation instead of single ones. If you wrote it like this :
"onclick=\'OpenWindow();\'";
it will never work! You have to use double quotations...
Also, since I am a C# developer, you have to use the \" code to write double quotations otherwise, you will get compiler error.
I hope this helps!

How to change the image on the ApplicationBar from C#?

I have a small C# project that has an ApplicationBar. But I have a small problem: I want 8 icons on the bar, and the ApplicationBar only supports 4. I came up with a solution (in C#): add a small CheckBox to ask if the user wants to use the first or second set of tools.But I'm still not able to change the icons on the ApplicationBar. I tried removing the old ones, first with ApplicationBar.MenuItems.Remove(Button1); and then with ApplicationBar.Buttons.Remove(Button1);
but neither worked. I tried changing the .IconUri property of the button, but that gave me a NullReferenceException.

I don't understand what you mean by changing it from "C#, not Silverlight". C# is a programming language and Silverlight is a framework. Nevertheless, the link you posted to explains exactly how you do it. The ApplicationBar is not a Silverlight control, it's part of the native OS. You can use the code in the link or do something like this:
firstAppBarButton = (ApplicationBarIconButton)ApplicationBar.Buttons[0];
firstAppBarButton.Text = "New Text";
firstAppBarButton.IconUri = new Uri("/appbarIcon.png",UriKind.Relative);
You need to get the ApplicationBarIconButton via the index (0 for first one, 1 for second etc..) instead of by name.

You can't refer to the application buttons by name. Try:
((ApplicationBarIconButton)ApplicationBar.Buttons[0]).Remove
I would also suggest that you do not present two groups of 4 icons to the user. The limit is 4 for a reason. Any more than that requires a UI re-think. Perhaps divide the functionality over a few pages?

The syntax above gave me a compile error. With some additional research, I got this to work for me:
ApplicationBar.Buttons.Remove((ApplicationBarIconButton) ApplicationBar.Buttons[0]);

Click Gmail Refresh button

I am writing a simple personal app that has a browser control and I want it to automatically "Refresh" gmail to check it more often than it does by default. There are monkey scripts that do this but I'm trying to add my personal style to it.
Anyhow, I've looked around and found everything but what I can do in csharp using the browser control.
I found this:
// Link the ID from the web form to the Button var
theButton = webBrowser_Gmail.Document.GetElementById("Refresh");
// Now do the actual click.
theButton.InvokeMember("click");
But it comes back with null in 'theButton' so it doesn't invoke anything.
Anyone have any suggestions?

It's been awhile since I've used JavaScript, but given the other answers and comments that there is no real ID associated with the element, could you do something like the following:
Search all Div's with an attribute of Role == 'Button' and an InnerHtml == 'Refresh'.
Once the correct InnerHtml is found, get the Element.
Invoke the click on the found Element.
Again, this may be blowing smoke, but thought I'd throw it out there.
edit: Just realized you are doing this with C# and a browser control; however, the concept would still be the same.

The best suggestion I could give you at this point involves an existing API that is used for .NET web browser based automation:
http://watin.org/
Since the div tag with the desired button really only seems to identify itself with the class name, you could use the Find.BySelector(“”) code included with the most recent version of watin.
