Android开发中怎么样实现屏幕切换监听功能

android:configChanges="keyboardHidden|orientation|screenSize|locale|layoutDirection" 

@Override
protected void onConfigurationChanged(Configuration newConfig) {
  super.onConfigurationChanged(newConfig);
  //=========切换屏幕时设置isPortrail的值，从而使PTZ在不同的位置显示
  if (newConfig.orientation == this.getResources().getConfiguration().ORIENTATION_PORTRAIT) {
    isPortrail = true;
    ArrayViews(mCurArrayMode, true);
  }
  //切换为横屏
  else if (newConfig.orientation == this.getResources().getConfiguration().ORIENTATION_LANDSCAPE) {
    isPortrail = false;
    ArrayViews(mCurArrayMode, true);
  }
  Log.e("onConfigurationChanged",""+"onConfigurationChanged");
}
