Android: EditText multi-line text inside BottomSheetDialog

Question

I have a bottom sheet dialog and there is an EditText in the layout. EditText - multi-line, maximum - 3. I put:

commentET.setMovementMethod(new ScrollingMovementMethod());
commentET.setScroller(new Scroller(bottomSheetBlock.getContext()));
commentET.setVerticalScrollBarEnabled(true);

but when the user starts to scroll the EditText text vertically, the BottomSheetBehavior and EditText capture events will not scroll vertically.

Does anyone know how to solve this problem?

Answer 1

Here is an easy way to do this.

yourEditTextInsideBottomSheet.setOnTouchListener(new OnTouchListener() {
  public boolean onTouch(View v, MotionEvent event) {
        v.getParent().requestDisallowInterceptTouchEvent(true);
        switch (event.getAction() & MotionEvent.ACTION_MASK){
        case MotionEvent.ACTION_UP:
            v.getParent().requestDisallowInterceptTouchEvent(false);
            break;
        }
        return false;
   }
});

Answer 2

I solve these problems as follows:

• I created a custom work around the behavior of the bottom sheet, expanding my own android BottomSheetBehavior:

  public class WABottomSheetBehavior<V extends View> extends BottomSheetBehavior<V> {
  private boolean mAllowUserDragging = true;
  
  public WABottomSheetBehavior() {
      super();
  }
  
  public WABottomSheetBehavior(Context context, AttributeSet attrs) {
      super(context, attrs);
  }
  
  public void setAllowUserDragging(boolean allowUserDragging) {
      mAllowUserDragging = allowUserDragging;
  }
  
  @Override
  public boolean onInterceptTouchEvent(CoordinatorLayout parent, V child, MotionEvent event) {
      if (!mAllowUserDragging) {
          return false;
      }
      return super.onInterceptTouchEvent(parent, child, event);
  }
  }
  

• EditText, EditText, setAllowUserDragging:

  commentET.setOnTouchListener(new View.OnTouchListener() {
  public boolean onTouch(View v, MotionEvent event) {
      if (v.getId() == R.id.commentET) {
          botSheetBehavior.setAllowUserDragging(false);
          return false;
      }
      return true;
  }
  });
