Android布局更改

我想为横向和纵向使用不同的布局。我已经把xml文件放在layout和land-land中。Android布局更改

对于我的父母活动，我设置了android：configChanges =“keyboardHidden | orientation | screenSize”，所以我想自己处理方向更改。

我已经试过这手动更改布局：

@Override 
public void onConfigurationChanged(Configuration newConfig) { 
    super.onConfigurationChanged(newConfig); 

    getFragmentManager().beginTransaction().replace(R.id.content_frame, new FoodDashboardFragment()).commit(); 
}

它的工作原理......但要主屏幕时，应用程序崩溃...所以...我猜我失踪一些东西。是否有另一种（简单）的方式来做到这一点？

这里是日志：
