Question

我尝试为应用程序制作一些简单的小部件。但它不起作用。在新的明确申请（没有活动）一切都很好。在我的应用程序中，列表中没有小部件。我认为问题显而易见，但我无法解决它。以下是来源：

MyWidgetProvider.java：

public class MyWidgetProvider extends AppWidgetProvider {

    private static final String ACTION_CLICK = "ACTION_CLICK";

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

        // Get all ids
        ComponentName thisWidget = new ComponentName(context,
                MyWidgetProvider.class);
        int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
        for (int widgetId : allWidgetIds) {
            // Create some random data
            int number = (new Random().nextInt(100));

            RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                    R.layout.widget_layout);
            Log.w("WidgetExample", String.valueOf(number));
            // Set the text
            remoteViews.setTextViewText(R.id.update, String.valueOf(number));

            // Register an onClickListener

            intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
            intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);

            PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
                    0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
            remoteViews.setOnClickPendingIntent(R.id.update, pendingIntent);
            appWidgetManager.updateAppWidget(widgetId, remoteViews);
        }
    }
}

widget_layout.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>

widget_provider.xml：
