Answer 1

You can do it by overriding onKeyLongPress() like

@Override 
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) 
{ 
    TextView myTextView = (TextView) findViewById(R.id.myTextView);
    myTextView.setText("");
    return true; 
} 
return super.onKeyLongPress(keyCode, event);

}

Answer 2

Try this

@Override 
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
  if (keyCode == KeyEvent.KEYCODE_DEL) 
  { 
    textView.setText("");
    return true; 
  } 
return super.onKeyLongPress(keyCode, event);
