Question

当我从横向模式启动我的应用程序时，它完美运行。但是，当我尝试从纵向模式切换到横向模式时，它会崩溃。我在纵向模式下使用导航抽屉，在横向模式下使用线性布局。

代码：

HomeMainFragment Mfrag;
HomeSideFragment Afrag;
DrawerLayout drawer;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_home); // Line 45  

    int screenconfig=getResources().getConfiguration().orientation;

     Mfrag=new HomeMainFragment();       
     Afrag=new HomeSideFragment();

    if(screenconfig==Configuration.ORIENTATION_PORTRAIT){     
    drawer=(DrawerLayout)findViewById(R.id.DrawerL);

 getFragmentManager().beginTransaction().replace(R.id.fm_homesidefrag, Afrag).
    setCustomAnimations(android.R.anim.slide_in_left,   android.R.anim.slide_out_right).commit();       
    }               
        getFragmentManager().beginTransaction().replace(R.id.fm_homemainfrag, Mfrag).
        setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right).commit();

}
