android - 无法让广播接收器处理具有多个操作的 Intent

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一个操作类型。然而，接收者似乎永远不会接收到它。 Intent 确实被调用，因为我可以调试并在 IntentService 中设置断点并看到操作被成功处理。我从来没有看到文本框更新了适当的数据，也没有看到 BroadcastReceiver 被调用。

Intent 服务

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);
}

Broadcast Receiver 作为 Main Activity 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，其包与 Main Activity 不同。

Answer 1

因为接收器的存在是为了在 Activity 中更新数据，所以应该在 Activity 恢复时注册，在 Activity 暂停时取消注册。它不应该出现在 list 中(参见 the doc)。

如果不是这种情况，它不应该是您 Activity 的子类。

在所有情况下，我认为您的 Receiver 没有被调用，因为它在 list 中的名称不正确。它可能是这样的:.MainActivity$CheckinReceiver。
