  <pre><code>@Override
  public boolean onKeyUp(int keyCode, final KeyEvent event) {
      final int finalKeyCode = keyCode;
      View lView = mParent.lET.findFocus();
      if(lView == mParent.lET)
      {
          if(keyCode == KeyEvent.KEYCODE_ENTER)
          {
              this.mGLThread.androidHideSoftKeyboard();
          }
          else
          {
              mParent.lET.bringToFront();
              mParent.lET.onKeyUp(finalKeyCode, event);
              mPlayerName = mParent.lET.getText().toString();
          }
      }
  
      return false;
  }
