后台服务不工作 - Android

Question

我尝试每两秒运行我的服务中的一个方法，但是当我启动服务时只运行一次这是相关代码：

启动服务：

 mViewHolder.mLinearLayoutContainer.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent launchIntent = view.getContext().getPackageManager().getLaunchIntentForPackage(mListStorage.get(position).getAdrress());

            mApkPackage = mListStorage.get(position).getAdrress();
            Intent intent = new Intent(view.getContext(), KillerService.class);
            if(mApkPackage != null){
                intent.putExtra("NAMEAPK", mApkPackage);
                view.getContext().startService(new Intent(view.getContext().getApplicationContext(), KillerService.class));
                view.getContext().bindService(intent,mServiceConnection, Context.BIND_AUTO_CREATE);
            }


            if (launchIntent != null) {
                view.getContext().startActivity(launchIntent);//null pointer check in case package name was not found
            }
        }
    });

这是我的服务 class:

@Override
protected void onHandleIntent(@Nullable Intent intent) {
    final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            //mAppsNames();
            Log.d("SYSTEMRUNNIGKILLI", "matandoapps");

        }
    }, 2000);
}


@Nullable
@Override
public IBinder onBind(Intent intent) {

    mApkName = intent.getStringExtra("NAMEAPK");
    Log.d("HOLAXD", mApkName);

    return null;
}




@Override
public void onCreate() {
    super.onCreate();
}

Log.d("SYSTEMRUNNIGKILLI", "matandoapps"); 的部分只是运行一次，而不是每 2 秒一次。

Answer 1

您使用了错误的方法每 2 秒调用一次代码。试试用这个方法

      new Timer().scheduleAtFixedRate(new TimerTask() {
            @Override
            public void run() {}
        }, 0, 1000); //1000 miliseconds equal to 1 second

Answer 2

另一种方法只需添加 handler.postDelayed(this,2000);

 final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            //mAppsNames();
            Log.d("SYSTEMRUNNIGKILLI", "matandoapps");

            handler.postDelayed(this,2000);
        }
    }, 2000);
