android 10秒后执行,在后台每10秒执行一次特定任务(android)

我正在开发android应用程序，我希望在每10秒后做一些事情。即使应用程序是封闭的。为此，我实现了一个后台服务，为我做后台任务。我的代码结构如下所示：

// my main activity

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Button start = (Button)findViewById(R.id.serviceButton);

Button stop = (Button)findViewById(R.id.cancelButton);

start.setOnClickListener(startListener);

stop.setOnClickListener(stopListener);

}

private OnClickListener startListener = new OnClickListener() {

public void onClick(View v){

startService(new Intent(SimpleServiceController.this,SimpleService.class));

}

};

private OnClickListener stopListener = new OnClickListener() {

public void onClick(View v){

stopService(new Intent(SimpleServiceController.this,SimpleService.class));

}

};

//simpleservice

@Override

public IBinder onBind(Intent arg0) {

// TODO Auto-generated method stub

return null;

}

@Override

public void onCreate() {

super.onCreate();

Toast.makeText(this,"Service created ...", Toast.LENGTH_LONG).show();

}

@Override

public void onDestroy() {

super.onDestroy();

Toast.makeText(this, "Service destroyed ...", Toast.LENGTH_LONG).show();

}这工作正常。但是当我每10秒开始服务时，我现在要做的就是给我简单的Toast消息，并且当我停止服务时停止Toast消息。

我也尝试使用AlarmManager。

// main activity....

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

}

public void startAlert(View view) {

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

PendingIntent pendingIntent = PendingIntent.getBroadcast(

this.getApplicationContext(), 234324243, intent, 0);

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()

+ (10 * 1000), pendingIntent);

Toast.makeText(this, "Alarm set in " + 10 + " seconds",

Toast.LENGTH_LONG).show();

}

// broadcast receiver

public class MyBroadcastReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

Toast.makeText(context, "Don't panik but your time is up!!!!.",

Toast.LENGTH_LONG).show();

}

}但我无法定期做到这一点。

什么是实施这个的正确方法？需要帮助...谢谢...
