android - 我的服务在后退按钮后停止

Question

我有一个服务和一个交流的 Activity 。当我单击按钮时(我有 galaxy s3，只有一个按钮)然后我的 Activity 当然消失并且我的服务继续运行但是如果我单击后退(触摸)按钮然后我的服务被破坏。我该如何更改它？我希望服务继续运行，直到 Activity 破坏它。

代码如下:

服务: 公共(public)类 MyService 扩展服务 { private static final String TAG = "BroadcastService"; public static final String BROADCAST_ACTION = "com.websmithing.broadcasttest.displayevent"; 私有(private)最终处理程序处理程序=新处理程序()； 私有(private) Intent ; int 计数器 = 0;

    @Override
    public void onCreate() 
    {
        super.onCreate();
        intent = new Intent(BROADCAST_ACTION);  
    }

    @Override
    public void onStart(Intent intent, int startId) 
    {
       // handler.removeCallbacks(sendUpdatesToUI);
        handler.postDelayed(sendUpdatesToUI, 1000); // 1 second

    }

    private Runnable sendUpdatesToUI = new Runnable() {
        public void run() {
            DisplayLoggingInfo();           
            handler.postDelayed(this, 1000); // 10 seconds
        }
    };    

    private void DisplayLoggingInfo() {
        intent.putExtra("counter", String.valueOf(++counter));
        sendBroadcast(intent);
    }

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onDestroy() {       
        handler.removeCallbacks(sendUpdatesToUI);       
        super.onDestroy();
    }       
}

Activity :

public class MainActivity extends Activity {
    private static final String TAG = "BroadcastTest";
    private Intent intent;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        intent = new Intent(this, MyService.class);

        startService(intent);
        registerReceiver(broadcastReceiver, new IntentFilter(MyService.BROADCAST_ACTION));
    }

    private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            updateUI(intent);       
        }
    };    


    @Override
    public void onDestroy() {
        super.onPause();
        unregisterReceiver(broadcastReceiver);
        stopService(intent);        
    }   

    private void updateUI(Intent intent) 
    {
        String counter = intent.getStringExtra("counter"); 
        Log.d(TAG, counter);

        TextView txtCounter = (TextView) findViewById(R.id.textView1);
        txtCounter.setText(counter);
    }
}

您可以将您的应用程序置于后台而不是完成它。

   @Override
    public void onBackPressed() {
     moveTaskToBack(true);
    // super.onBackPressed();
    }
