I have a ScrollView in my app and now I would like to scroll to the bottom of he screen in the Android Studio preview-window, but I don't really know how to do that. Is that possible, or is there an option to switch to a "fullscreen" mode?
I might be totally wrong here but I have never seen that someone did that. The basic reason must be that there is no way to tell how many entries the ListView might have.

I noticed something strange after implementing and testing a settings screen for my TV app using the LeanbackSettingsFragmentCompat class, please see attached image:
As you can see, after navigating with the remote to other items, the items no longer in focus still retain their focused background state, I was only able to reproduce this behaviour on one device, and it rarely happens
This problem has left me a bit perplexed,as this is not my implementation but rather Leanback's.. But still, I have never seen a TV app with this problem
Has anyone ever encountered such an issue? Could I have made a mistake to cause something like that?
I would be happy to share code, but at this point I don't know if my code is even relevant to this problem
Thanks in advance
So I have been trying to create a pretty basic calculator app.
I converted my RelativeLayout to a ConstraintLayout and started creating constraints.
After some time I noticed that while creating new constraints, the older ones get deleted.
Why is this happening?
I'm pretty new to Android development so I'm just trying to learn Android, my apologies if this is a low quality question.
Hoping to see some answer regarding this happening. I did some research on Google & YouTube and StackExchange, I'm sure I did everything correctly, just the constraints themself started disappearing after some time.
That could happen because constrain layout is still in beta. This will come with a lot of bug like these for instance. It could happen that it deleted all the constrains or maybe u accidentally pressed the 'clear all constrains' button in android studio.
You can check if constrains are still there by looking in to the text tab in edition to the design tab. And look for
app:layout_constraintRight_toRightOf="parent"
or any other variaty.
Since the constraint layout is still in beta. I would recommend just using the other layouts of android (Linear, grid, relative etc.).
I am trying to create the UI but I'm having a lot of difficulty just placing controls where I want them to appear on the main screen. For example I want to add a few ImageButtons but they just seem to snap to one corner and I can't seem to add more than one.
Do I need to use a layout or something? Can't I just drag and drop and move the controls around where I want?
I suggest you start by reading a few of the developer tools out there. http://developer.android.com/guide/topics/ui/declaring-layout.html This guide will help you get your feet wet with how to properly layout a screen in Android. There are also a bunch of other great guides on there to help with other aspects of the UI. Even though you use C# in Xamarin Studio, the UI portion is native Android so the guides should still be relevant.
try to use relative layout , its kind of easy for visual studio developer and others too.

I'm devolopping a tablet app. I want it to work full screen. After days of investigeting on google, I achived it using:
.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
.getWindow().getDecorView().setSystemUiVisibility(Window.FEATURE_ACTION_BAR_OVERLAY);
.getWindow().getDecorView().setSystemUiVisibility(Window.FEATURE_ACTION_MODE_OVERLAY);
The Tablet I'm using is 4.1 Android version. That was working perfectly though I had to made some changes like doing my own action bar (because sistem action bar made navigation buttons comes up) and dialogs.
Now the problem is that I've installed my application on 4.2 Android version and it's a disaster. Each time I touch the screen, navigation buttons comes up. It's really annoying. This is driving me mad, I've tried many things but it's still coming up.
Is there a way to solve this problem? I think if I could override the method that makes navigation buttons comes up I could achieve my objective. Anybody know which is this method??
It is not working in 4.0 Android version neither. That doesn't bother me much, but if you know a way to solve it as well, that would help me a lot.
I would appreciate any help. Thanxs a lot.
Each time I touch the screen, navigation buttons comes up.
One of the core Android concepts is that the user is always in control of the UI. If developers were allowed to create fullscreen Apps and override the navigation buttons, it would be trivial for an App (rogue or otherwise) to create a screen which the user could not get out from.
If you really want to remove the system bar, you will system-level access or you need to build your own custom Android.
Does anyone know of something similar to GMGridview for MonoDevelop and Android?
I am looking for something that will allow me to place about 12 to 15 icons/buttons on the Android that I can swipe/scroll back and forth. I am using MonoDevelop and am very new to Android Development.
I do not necessarily need the drag and drop functionality, but I cannot even find an example of placing many icons on the screen and allowing me to scroll back and forth.
I am struggling with how the layout should be done so any help is appreciated!!
Thank you for any assistance!!!
GridView... ?

And I have no idea how is it connected with MonoDevelop.
