ScrollView Not working when keyboard is showing in android

Question

My problem is when keyboard is open scrollview is not working. Means basically when I have Theme android:theme=\"@android:style/Theme.Black.NoTitleBar.Fullscreen\"

Answer 1

I got the same problem. The fullcreen mode prevents the scrolling.

In concrete, I tested several FLAGS and LAYOUTS. These are working and don't prevent scrolling:

View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
View.SYSTEM_UI_FLAG_FULLSCREEN
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
View.SYSTEM_UI_FLAG_LAYOUT_STABLE

These are preventing the scrolling and do not work:

View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN

So I got a workaround finally, took me some days, but it works!

1. Choose a theme, that is not fullscreen in manifest.xml, e.g.:

   android:theme="@android:style/Theme.DeviceDefault.Light.NoActionBar"
   

2. Add this code, that makes your activity fullscreen

   private static View systemUIView;
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       super.setContentView(R.layout.rootlayout); //your layout with the scrollview
   
       // hide the native android navigation and status bar
       systemUIView = getWindow().getDecorView();
       hideSystemUI();
   
       if (android.os.Build.VERSION.SDK_INT >= 19) {
           getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(
                   new OnSystemUiVisibilityChangeListener() {
                       @Override
                       public void onSystemUiVisibilityChange(int visibility) {
                           if (visibility == 0) {
                               hideSystemUI();
                           }
                       }
                   });
       }
   
   // ... here comes my whole code...      
   }
   
   @Override
   public void onResume() {
       super.onResume();
       hideSystemUI();
   }
   
   public void hideSystemUI() {
       systemUIView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
           | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
           | View.SYSTEM_UI_FLAG_FULLSCREEN
           | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
   }
   

The systembar and navigation bar disappears. The reason for this is, because I have set IMMERSIVE_STICKY. It is whole lot of work to test it all around. I hope this helps you all, or atleast gives you the right direction.

Remember, that a Fullscreen-Theme will always prevent you from scrolling while the softkeyboard is up. I am referencing to Android 4.4(KitKat).
