Question

实际上，我已经开发了我的Android应用程序版本10（2.33），但是我发现了这个问题，当我在移动设备上运行应用程序时，它工作正常但是有一段时间后移动设备进入睡眠模式，当我启用或解锁时然后，设备观察到，当设备的方向改变时，应用程序显示由用户填充的内容被清理并且内容恢复。先生，请在此事先帮助我。我还绑定了onCretae方法的源代码。

@覆盖 public void onCreate（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）; 尝试{

    setContentView(R.layout.main);
    ListView lstMain = (ListView) findViewById(R.id.lstMain);
    btnSetting =(Button)findViewById(R.id.btnSetting);
    btnCheck = (Button)findViewById(R.id.btnCheckStatus);
    btnabout = (Button)findViewById(R.id.btnabout);
    imgUserAdmin = (ImageView)findViewById(R.id.imgUserAdmin);
    btnCheck.setOnClickListener(buttonhandler);
    btnSetting.setOnClickListener(buttonhandler);
    btnExit = (Button)findViewById(R.id.btnExit);
    btnLocation = (Button)findViewById(R.id.btnAddSelLocation);
    btnLocation.setOnClickListener(buttonhandler);
    btnExit.setOnClickListener(buttonhandler);        
    startService(new Intent(this,SmsService.class));

    registerReceiver(smsSend.sms_send,smsSend.getSentIntentFilter());

    registerReceiver(receivedSms,filter);
   lstMain.setOnItemClickListener(lstMainClick);

     if(!Integer.toString(id).equals(ConstantClass.isCrdDiffer))
         ConstantClass.isAuditrequestSend=true;
     if(ConstantClass.isAuditrequestSend==false)
        btnCheck.setText("Checking..");
    String c = null;

            cursor.moveToFirst();

        startManagingCursor(curMain);
        if(curMain.getCount()>0){

            adpt = new customCursorAdapter(this,curMain);  
            lstMain.setAdapter(adpt);           
        }

    }else{
