Android笔记（24）Service重复任务

1.在Manifest里面声明服务

<service android:enabled="true" android:name=".MyService"/>

2.新建MyService类

import android.app.Service;
import android.content.Intent;
import android.os.Handler;
import android.os.IBinder;

import java.text.SimpleDateFormat;
import java.util.Timer;
import java.util.TimerTask;

public class MyService extends Service {
@Override
public IBinder onBind(Intent intent) {
return null;
    }

@Override
public void onCreate() {
new Timer().schedule(new TimerTask() {
@Override
public void run() {
//任务内容
            }
        },0,5000);
    }

@Override
public void onDestroy() {
    }

@Override
public void onStart(Intent intent, int startid) {
    }
}

3.Activity

startService(new Intent(this, MyService.class));
