Question

我有一项活动可以开始我的服务。启动后，服务应该在片段中发送数据。在宽阔的沟渠上显示服务已经启动，已经开始运营，但是片段没有发出广泛的沟渠，表明它已经获得了数据。我怎样才能进行这样的连锁活动 - ＆gt;服务 - ＆GT;一个片段？

main.java（活动）

kill = new Intent(this, timer.class);

        pi = createPendingResult(TASK1_CODE, kill, 0);

        intent = new Intent(this, timer.class).putExtra(PARAM_TIME, 7)
                .putExtra(PARAM_PINTENT, pi);

        startService(intent);

        pi = createPendingResult(TASK2_CODE, kill, 0);
        intent = new Intent(this, timer.class).putExtra(PARAM_TIME, 4)
                .putExtra(PARAM_PINTENT, pi);
        startService(intent);

        pi = createPendingResult(TASK3_CODE, kill, 0);
        intent = new Intent(this, timer.class).putExtra(PARAM_TIME, 6)
                .putExtra(PARAM_PINTENT, pi);
        startService(intent);

timer.java（服务）

 public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d(LOG_TAG, "MyService onStartCommand");
        int time = intent.getIntExtra(user_rassp.PARAM_TIME, 1);
        PendingIntent pi = intent.getParcelableExtra(user_rassp.PARAM_PINTENT);

    MyRun mr = new MyRun(time, startId, pi);
    es.execute(mr);
    return START_REDELIVER_INTENT;
}

@Override
public IBinder onBind(Intent intent) {
    return null;
}

class MyRun implements Runnable {

    int time;
    int startId;
    PendingIntent pi;

    public MyRun(int time, int startId, PendingIntent pi) {
        this.time = time;
        this.startId = startId;
        this.pi = pi;
        Log.d(LOG_TAG, "MyRun#" + startId + " create");
    }

    public void run() {
        Log.d(LOG_TAG, "MyRun#" + startId + " start, time = " + time);
        try {

            pi.send(user_rassp.STATUS_START);

            TimeUnit.SECONDS.sleep(time);


            Intent intent = new Intent().putExtra(user_rassp.PARAM_RESULT, time * 100);
            Log.d(LOG_TAG, "конец");
            pi.send(timer.this, user_rassp.STATUS_FINISH, intent);

        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (PendingIntent.CanceledException e) {
            e.printStackTrace();
        }
        stop();
    }

    void stop() {
        Log.d(LOG_TAG, "MyRun#" + startId + " end, stopSelfResult("
                + startId + ") = " + stopSelfResult(startId));
    }
}

user_rasp.java（片段）

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d(LOG_TAG, "requestCode = " + requestCode + ", resultCode = "
            + resultCode);

    // Ловим сообщения о старте задач
    if (resultCode == STATUS_START) {
        switch (requestCode) {
            case TASK1_CODE:
                Log.d("task1","start");
                break;
            case TASK2_CODE:
                Log.d("task1", "start");
                break;
            case TASK3_CODE:
                Log.d("task1", "start");
                break;
        }
    }

    // Ловим сообщения об окончании задач
    if (resultCode == STATUS_FINISH) {
        int result = data.getIntExtra(PARAM_RESULT, 0);
        switch (requestCode) {
            case TASK1_CODE:
                Log.d("Task1", "finish, result = " + result);
                break;
            case TASK2_CODE:
                Log.d("Task2", "finish, result = " + result);
                break;
            case TASK3_CODE:
                Log.d("Task3", "finish, result = " + result);
                break;
        }
    }
}

Answer 1

在Fragment中注册BroadCastReceiver。你需要为它使用一个动作。

来自Service发送带有上述Intent Action的broadcastMessage。您可以通过Intent extras传递数据

onActivityResult从服务到片段
