Question

我尝试每两秒钟在服务中运行一种方法，但是当我启动服务时，仅运行一次这是相关代码：

启动服务：

shoppinglist_file.write("%s\n" % (thing_to_add))

这是从我的Service类中获得的：

 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
            }
        }
    });

@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(); }的一部分仅运行一次，而不是每2秒运行一次。

Answer 1

每2秒使用一次错误的方法来调用代码。尝试使用此方法

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

Answer 2

另一种方法是添加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);
