前言

公司之前做的一個(gè)電視機(jī)上的播報(bào)應(yīng)用（類似于銀行的那種播報(bào)“請某某某到幾號窗口”），現(xiàn)在要我做個(gè)定時(shí)重啟

正題

整體思路：定時(shí)任務(wù)在服務(wù)里執(zhí)行，當(dāng)時(shí)間等于某個(gè)特定的值就重啟
服務(wù)的代碼：

/**
 * Created by mk_who on 2017/8/3/0003.
 */
public class MyService extends Service {

    private IBinder mBinder=new Binder();
    private Timer mTimer;
    private TimerTask mTimerTask;
    private Intent intent = new Intent("com.example.restart.RECEIVER"); 
    
    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }

    @Override
    public void onCreate() {
        mTimer = new Timer();
        mTimerTask = new TimerTask() {
            @Override
            public void run() {
                new Thread(new Runnable() {
                    @Override
                    public void run() {
                        SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
                        String dateStr = sdf.format(new Date());
                        if (dateStr.equals("16:20")){
              
                            sendBroadcast(intent);//發(fā)送廣播
                      
                        }
                    
                    }
                }).start();
            }
        };
        mTimer.schedule(mTimerTask,5000,59000);
        mTimer=null;
        mTimerTask=null;
    }
    @Override
    public void onDestroy() {
        super.onDestroy();
        mTimer.cancel();
        mTimerTask.cancel();
    }
}

開啟服務(wù)的頁面的部分代碼：

private void startMyService() {
        Intent intent = new Intent(getApplicationContext(), MyService.class);
        
        bindService(intent, connServiceconn, BIND_AUTO_CREATE);
    }
    private Serviceconn connServiceconn = new Serviceconn();
    private class Serviceconn implements ServiceConnection {

        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            Log.e("--------", "------開啟服務(wù)成功---");
        }

        @Override
        public void onServiceDisconnected(ComponentName name) {

        }
    }
    @Override
    protected void onResume() {
        super.onResume();
        startMyService();//開啟服務(wù)
        filter.addAction("com.example.restart.RECEIVER");
        registerReceiver(reStartReceiver, filter);
    }

service跟activity通信的廣播代碼：

private BroadcastReceiver reStartReceiver = new BroadcastReceiver(){
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (action.equals("com.example.restart.RECEIVER")) {
                finish();
                Intent i = Main.this.getPackageManager()
                        .getLaunchIntentForPackage(Main.this.getPackageName());
                i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(i);
            }
        }
    };

當(dāng)時(shí)是下午五點(diǎn)半（六點(diǎn)鐘下班）接到的任務(wù)，著急下班吃飯（就是不想加班），就用了能想到的最簡單的實(shí)現(xiàn)方式。
