如何在 remoteview 的帮助下创建 Listview？

Question

我正在尝试在 remoteview 的帮助下在小部件中创建动态 listview，因为我想要小部件中的这个 listview 应用程序图标。我想显示来自应用程序明智的所有应用程序的传入通知。我想创建常设通知列表，当用户从列表视图中单击应用程序图标时，将显示该特定通知。我正在使用 API 19 获取所有通知并且也成功了，但我不知道如何使用 Remoteview 和 drawables(Icons).[=17 在小部件中创建 Listview =]

您是否搜索或尝试过其他在小部件中包含 ListView 的示例？请查看 github 上可用的 Weather Widget demo。

代码：

    public class MyWidgetProvider extends AppWidgetProvider {

    private static HandlerThread sWorkerThread;
    private static Handler sWorkerQueue;

    public MyWidgetProvider() {
        // Start the worker thread
        sWorkerThread = new HandlerThread("MyWidgetProvider-worker");
        sWorkerThread.start();
        sWorkerQueue = new Handler(sWorkerThread.getLooper());
    }

    public void onUpdate(Context context, final AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        for (int i = 0; i < appWidgetIds.length; ++i) {
            ...
            final RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
            views.setRemoteAdapter(R.id.lvWidget, svcIntent);

            sWorkerQueue.postDelayed(new Runnable() {

                @Override
                public void run() {
                    // TODO Auto-generated method stub
                    views.setScrollPosition(R.id.list, 3);
                    appWidgetManager.partiallyUpdateAppWidget(appWidgetIds[i], views);
                }

            }, 1000);

            appWidgetManager.updateAppWidget(appWidgetIds[i], views);
            ...
        }
    }
}

其行为如下：

请检查 github 项目和上面的示例代码。

我已经尝试过@iDroid Explorer 的解决方案，来自他之前的一个答案。但是列表视图没有出现在边缘面板中（PS：我希望它在 galaxy note 边缘面板中实现）。

所以我尝试了以下代码：

    private RemoteViews updateWidgetListView(Context arg0, int i) {

        //which layout to show on widget
        RemoteViews remoteViews = new RemoteViews(arg0.getPackageName(),
                R.layout.activity_main_sub);

        //RemoteViews Service needed to provide adapter for ListView
        Log.d("fff", "updateWidget: "+ i);

        Intent svcIntent = new Intent(arg0, MyService.class);

        //passing app widget id to that RemoteViews Service
        svcIntent.putExtra("Id", i);
        Log.d("fff", "receiver:"+appnM);
        svcIntent.putExtra("appname", appnM);
        //setting a unique Uri to the intent
        //don't know its purpose to me right now
        svcIntent.setData(Uri.parse(svcIntent.toUri(Intent.URI_INTENT_SCHEME)));
        //setting adapter to listview of the widget

        remoteViews.setRemoteAdapter(i, R.id.list_icon,svcIntent);

//      remoteViews.setRemoteAdapter(i, svcIntent);

        arg0.startService(svcIntent);
        //setting an empty view in case of no data
        remoteViews.setEmptyView(R.id.list_icon, R.id.empty_view);

        Log.d("fff","end of myReceiver");
        return remoteViews;
    }

并且在 myService class 中我已经在列表中填充了必需的项目。

我从一个名为 WidgetListView1 的示例中得到了帮助，它是我从随机搜索中找到的。
