android - 在应用程序内截取屏幕截图

Question

我有一个覆盖 onKeyDown 的应用程序。这是方法:

    @Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        // my stuff     
       }
}

现在，如果我尝试在我的应用程序中截取屏幕截图，长按截取屏幕截图所需的按钮似乎不起作用。是否有一种不那么痛苦的方法可以再次截取屏幕截图？

附言对不起我的英语

  @Override
  public boolean onKeyDown( int keyCode, KeyEvent event ) {
    if( keyCode == KeyEvent.KEYCODE_BACK ) {
      event.startTracking();
      return true; 
    }
    return super.onKeyDown( keyCode, event );
  }

  @Override
  public boolean onKeyUp( int keyCode, KeyEvent event ) {
    if( keyCode == KeyEvent.KEYCODE_BACK ) {
      //Your stuff. (Handle what you want on short press).      
      return true; 
    }

    return super.onKeyUp( keyCode, event );
  }

  @Override
  public boolean onKeyLongPress( int keyCode, KeyEvent event ) {
    if( keyCode == KeyEvent.KEYCODE_BACK ) {
      //Handle what you want in long press.
      return true;
    }
    return super.onKeyLongPress( keyCode, event );
  }
