Android版的onReceive不叫

问题描述

我想按照这个例子：
What是AppWidgetProvider之间共享数据和RemoteViewsService.RemoteViewsFactory

因此​​，我有一个 RemoteViewsFactory 有这样的：

As such, I have a RemoteViewsFactory that has this:

@Override
public void onDataSetChanged() {
    // Subsequent calls to get the data.
    newsGetter.updateListFeed(null, new NewsGetter.OnUpdateListFeedFinishedListener() {
        @Override
        public void onUpdateListFeedFinished(VolleyError error) {
            //async return here from volley

            Intent widgetUpdateIntent = new Intent(NewsWidgetBase.FEED_UPDATED);
            widgetUpdateIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
            LocalBroadcastManager.getInstance(context).sendBroadcast(widgetUpdateIntent);
        }
    });

    Log.e(TAG, "******************************** onDataSetChanged PROVIDER");
}

然后我有一个 AppWidgetProvider 有这样的：

@Override
public void onReceive(Context context, Intent intent) {

    final String action = intent.getAction();

    if (AppWidgetManager.ACTION_APPWIDGET_UPDATE.equals(action)) {
        Log.e("WidgetBase", "******************************** onReceive ACTION_APPWIDGET_UPDATE");
    } else if (FEED_UPDATED.equals(action)) {
        Log.e("WidgetBase", "******************************** onReceive FEED_UPDATED");

        AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
        int appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
                AppWidgetManager.INVALID_APPWIDGET_ID);
        updateAppWidget(context, appWidgetManager, appWidgetId);
    }

    super.onReceive(context, intent);
}

和在清单：

    <receiver android:name=".widgets.a">
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
            <action android:name="com.myapp.FEED_UPDATED" />
        </intent-filter>

        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/abc" />
    </receiver>

我得到的调试日志 ACTION_APPWIDGET_UPDATE ，但对我自己的意图广播，它永远不会触发的onReceive （断点永远不会连打）。有谁看到我在做什么错了？

I get the debugger log for ACTION_APPWIDGET_UPDATE, but for my own Intent broadcast, it never fires onReceive (breakpoint is never even hit). Does anyone see what I'm doing wrong?

推荐答案

有关你自己的意图广播工作，你必须注册你的广播接收器编程。因此，注册您的接收器

For your own Intent broadcast to work, you have to register your BroadcastReceiver programmatically. So register your receiver as

LocalBroadcastManager.getInstance(this).registerReceiver(YourWidgetReceiver, new IntentFilter("your_intent_action"));

然后发送广播为

Intent intent = new Intent("your_intent_action");
LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(intent)

希望这有助于。
