RemoteView小部件将不显示图像和文本

Question

我试图用提供的图像（使用滑行从互联网加载的图像）和文本制作stackwidget。这两个值都存在，但是当我尝试将其分配给像这样的rv.setImageViewBitmap(R.id.img_widget,bmp);时，它什么也没显示。

这是WidgetFactory的代码

private MovieFavorite getFav(int position) {
    if (!cursor.moveToPosition(position)) {
        throw new IllegalStateException("Position invalid!");
    }

  return new MovieFavorite(cursor.getString(cursor.getColumnIndexOrThrow(
            MovieContract.MovieColumns.MOVIE_ID)),
          cursor.getString(cursor.getColumnIndexOrThrow(MovieContract.MovieColumns.MOVIE_IMAGE)),
          cursor.getString(cursor.getColumnIndexOrThrow(MovieContract.MovieColumns.MOVIE_TITLE)));
}


@Override
public void onCreate() {
    cursor = mContext.getContentResolver().query(
            MovieContract.CONTENT_URI,
            null,
            null,
            null,
            null
    );

}

@Override
public void onDataSetChanged() {
    if (cursor != null) {
        cursor.close();
    }
    final long identityToken = Binder.clearCallingIdentity();
    cursor = mContext.getContentResolver().query(
            MovieContract.CONTENT_URI, null, null, null, null);
    Binder.restoreCallingIdentity(identityToken);
}

@Override
public void onDestroy() {
    if (cursor != null) {
        cursor.close();
    }
}

@Override
public int getCount() {
    return cursor.getCount();
}

@Override
public RemoteViews getViewAt(int position) {
    MovieFavorite movieFavorite = getFav(position);
    RemoteViews rv = new RemoteViews(mContext.getPackageName(), R.layout.movie_widget);

    Log.d("Widgetku",movieFavorite.getTitle());


    Bitmap bmp = null;
    try {
        bmp = Glide.with(mContext)
                .asBitmap()
                .load(UtilsConstant.BASE_BACKDROP_URL_WIDGET+movieFavorite.getImage())
                .into(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL)
                .get();
        rv.setImageViewBitmap(R.id.img_widget,bmp);
        Log.d("Widgetku","Yessh");
    }catch (InterruptedException | ExecutionException e){
        Log.d("Widget Load Error","error");
    }

    rv.setTextViewText(R.id.tv_movie_title, movieFavorite.getTitle());
    Bundle extras = new Bundle();
    extras.putInt(MovieWidget.EXTRA_ITEM, position);
    Intent fillInIntent = new Intent();
    fillInIntent.putExtras(extras);

    rv.setOnClickFillInIntent(R.id.img_widget, fillInIntent);
    return rv;
}

这是窗口小部件服务的代码

public class MovieWidgetService extends RemoteViewsService { @Override public RemoteViewsFactory onGetViewFactory(Intent intent) { return new MovieRemoteViewsFactory(this.getApplicationContext(), intent); } @Override public void onCreate() { super.onCreate(); } }

最后是Widget类的代码

`

public static void updateAppWidget（上下文上下文，AppWidgetManager，appWidgetManager，                                 int appWidgetId）{

    Intent intent = new Intent(context, MovieWidgetService.class);
    intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
    intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));

    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.movie_widget);
    views.setRemoteAdapter(R.id.stack_view, intent);
    views.setEmptyView(R.id.stack_view, R.id.empty_view);

    Intent toastIntent = new Intent(context, MovieWidget.class);
    toastIntent.setAction(MovieWidget.TOAST_ACTION);
    toastIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);

    intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
    PendingIntent toastPendingIntent = PendingIntent.getBroadcast(context, 0, toastIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    views.setPendingIntentTemplate(R.id.stack_view, toastPendingIntent);

    appWidgetManager.updateAppWidget(appWidgetId, views);
}

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    // There may be multiple widgets active, so update all of them
    for (int appWidgetId : appWidgetIds) {
        updateAppWidget(context, appWidgetManager, appWidgetId);
    }
}

@Override
public void onEnabled(Context context) {
    // Enter relevant functionality for when the first widget is created
}

@Override
public void onDisabled(Context context) {
    // Enter relevant functionality for when the last widget is disabled
}
@Override
public void onReceive(Context context, Intent intent) {
    AppWidgetManager mgr = AppWidgetManager.getInstance(context);
    if (intent.getAction().equals(TOAST_ACTION)) {
        int appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
        int viewIndex = intent.getIntExtra(EXTRA_ITEM, 0);
        Toast.makeText(context, "Touched view " + viewIndex, Toast.LENGTH_SHORT).show();
    }
    super.onReceive(context, intent);
}

在此先感谢您的帮助！
