Android : Multi line text EditText inside BottomSheetDialog

Question

I have a bottom sheet dialog and exists EditText in layout. EditText is multiline, max lines is 3. I put :

commentET.setMovementMethod(new ScrollingMovementM         


        

Answer 1

I solve this issues with following way:

1. I created custom work around bottom sheet behavior extends native 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);
   }
   }
   

2. then set touch event of EditText and when user touching area of EditText I will be disable handling event by parent with calling method 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;
   }
   });

For those who are interested in Kotlin solution. Here it is

editText.setOnTouchListener { v, event ->
    v.parent.requestDisallowInterceptTouchEvent(true)
    when (event.action and MotionEvent.ACTION_MASK) {
        MotionEvent.ACTION_UP -> 
                      v.parent.requestDisallowInterceptTouchEvent(false)
    }
    false
}

Answer 3

Here is an easy way to do it.

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;
   }
});
