java - Android在IntentService中重复运行函数

Question

我有这个 IntentService 代码，它运行一次服务:

protected void onHandleIntent(Intent intent) {
    final ResultReceiver receiver = intent.getParcelableExtra("receiver");
    String command = intent.getStringExtra("command");
    Bundle b = new Bundle();
    b.putString("results", results);
    if(command.equals("query")) {
        receiver.send(1, Bundle.EMPTY);
        try {                   
            results = sendGetMessage();
            b.putString("results", results);
            receiver.send(2, b);
        } catch(Exception e) {
            b.putString(Intent.EXTRA_TEXT, e.toString());
            receiver.send(0, b);
        }    
    }
    this.stopSelf();
    Log.d("ServiceFinished", "ServerConnection.java Service has finished");
}

我希望我的 sendGetMessage() 函数每 5 秒重复运行一次，直到我停止服务。我该怎么做？

您可能希望将其放入自己的线程中并永远循环。

Thread thread = new Thread()
{
    @Override
    public void run() {
        try {
            while(true) {
                Thread.sleep(5000); // for the 5 seconds requirement
                results = sendGetMessage();
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
};

thread.start();
