Cannot Erase input EditText value .

[arsojosw]

final SwipeDismissDialog swipeDismissDialog = new SwipeDismissDialog.Builder(this)
.setLayoutResId(R.layout.dialog_add_user)
.build()
.show();
final EditText usernameEditText = (EditText) swipeDismissDialog.findViewById(R.id.et_username);
swipeDismissDialog.setOnKeyListener(new View.OnKeyListener() {
@OverRide
public boolean onKey(View v, int keyCode, KeyEvent event) {
EditText username = (EditText) v.findViewById(R.id.et_username);
Log.d("key", "onKey: "+keyCode);
Log.d("key", "onKey: "+event);
if(keyCode == KeyEvent.KEYCODE_DEL){
Toast.makeText(MainActivity.this, "delete this", Toast.LENGTH_SHORT).show();
return true;
}
return true;
}
});

I Need to press long enough to delete the input.
