Question

我很难让BroadcastReceiver处理我的IntentService响应。该服务处理多个不同的操作并返回操作类型。然而，接收器似乎永远不会捡起它。意图确实被调用，因为我可以在IntentService中调试和设置断点，并查看操作是否已成功处理。我从来没有看到使用适当的数据更新文本框或看到正在调用BroadcastReceiver evein。

IntentService

protected void onHandleIntent(Intent intent) {


        String action = intent.getAction();
        // Data the service was called with.
        Bundle incomingData = intent.getExtras();

        String key = incomingData.getString(KEY_APPKEY);
        String secret = incomingData.getString(KEY_SECRET);
        String collection = incomingData.getString(KEY_COLLECTION);

        CheckinManager cm = new CheckinManager(this.getApplicationContext(),key,secret,collection);

        Intent broadcastIntent = new Intent();

        broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT);


        if (action == ACTION_GET_POI) {
            Double lat = incomingData.getDouble(KEY_LATITUDE);
            Double lon = incomingData.getDouble(KEY_LONGITUDE);

            ArrayList<POI> nearbyPOIs = new ArrayList<POI>();
            //broadcastIntent.setAction(ACTION_GET_POI_PROCESSED);
            broadcastIntent.setAction("com.msalinger.checkinmanager.CheckinService.getPOIProcessed");
            try {
                nearbyPOIs = cm.getPOI(lat, lon);

                broadcastIntent.putExtra(OUT_KEY_RESULT, true);
                broadcastIntent.putExtra(OUT_KEY_ERROR, "");
                broadcastIntent.putParcelableArrayListExtra(OUT_KEY_POILIST, nearbyPOIs);
            } catch (JSONException ex) {
                Log.d(TAG,ex.getMessage() + "\n" + ex.getStackTrace());
                broadcastIntent.putExtra(OUT_KEY_RESULT, false);
                broadcastIntent.putExtra(OUT_KEY_ERROR, ex.getMessage());
            }

        }
        else if (action == ACTION_CHECK_IN) {
            // Do something
        }
        else if (action ==  ACTION_GET_CHECKINS) {
            // Do Something
        }
        else if (action == ACTION_FIND_NEARBY_POIS_WITH_CHECKINS) {
            // Do Something 
        }    

        sendBroadcast(broadcastIntent);
}

广播接收器作为主要活动的子类

public class CheckinReceiver extends BroadcastReceiver {

        private final static String INTENT_BASE_URI = "com.msalinger.checkinmanager.CheckinService";

        private final static String ACTION_GET_POI_PROCESSED = ".getPOIProcessed";
        private final static String ACTION_CHECK_IN_PROCESSED = ".checkInProcessed";
        private final static String ACTION_GET_CHECKINS_PROCESSED = ".getCheckinsProcessed";
        private final static String ACTION_FIND_NEARBY_POIS_WITH_CHECKINS_PROCESSED = ".findNearbyPOIsWithCheckinsProcessed";


        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent.getAction().equals("com.msalinger.checkinmanager.CheckinService.getPOIProcessed")) {
                tv = (TextView)findViewById(R.id.textBox1);

                Bundle incomingData = intent.getExtras();
                String st = "";

                if (incomingData.getBoolean("result")) {
                    ArrayList<POI> poiList = incomingData.getParcelableArrayList("poList");
                    st = printPOI(poiList);
                }
                else {
                    st = incomingData.getString("error");
                }
            }
            else if (intent.getAction().equals(INTENT_BASE_URI + ACTION_CHECK_IN_PROCESSED)) {

            }
            else if (intent.getAction().equals(INTENT_BASE_URI + ACTION_GET_CHECKINS_PROCESSED)) {

            }
            else if (intent.getAction().equals(INTENT_BASE_URI + ACTION_FIND_NEARBY_POIS_WITH_CHECKINS_PROCESSED)) {

            }
        }

    }

我做错了什么？请注意，IntentService作为Android类库的一部分存在，其包含与Main活动不同的包。

Answer 1

因为接收器存在更新活动中的数据，所以应该在活动恢复时注册，并在活动暂停时注销。它不应该在清单中（请参阅the doc）。

如果不是这样，那么它不应该是您活动的子类。

在所有情况下，我认为您的Receiver未被调用，因为它在清单中没有正确的名称。它可能是这样的：.MainActivity$CheckinReceiver。

无法让广播接收器处理具有多个操作的意图
