活动在轮换时关闭

Question

我的活动正在接近轮换.不知道为什么？

此外,我检查了这个问题: 在Android上旋转活动重启 但无法找到解决方案.

这是我的oncreate函数:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.manage);


    //Defining and Getting Saved Preferences
    data=getSharedPreferences("cybapps", 0);
    dataeditor=data.edit();

    //To Delete all Preferences
    dataeditor.clear();
    dataeditor.commit();

   //Declaration 

    btn_delete=(Button)findViewById(R.id.btn_delete);
    btn_schedule=(Button)findViewById(R.id.btn_schedule);
    btn_deschedule=(Button)findViewById(R.id.btn_deschedule);
    profilelist=(ListView)findViewById(R.id.profilelist);
    am=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
    status=(TextView)findViewById(R.id.status);
    random=new Random(); 

   btn_delete.setOnClickListener(this);
    btn_schedule.setOnClickListener(this);
    btn_deschedule.setOnClickListener(this);

  //Listout all profiles
    listout();
}
