Question

我的应用存在一些问题。我从内容提供者那里获取了一些图像，并试图在stackview小部件中显示它们，但是无法单击stackview小部件，它只显示很少的图像（与小部件尺寸不匹配）。这是小部件的屏幕截图：

这是我的窗口小部件提供程序类：

public class FavMovieWidget extends AppWidgetProvider {
public static final String TOAST_ACTION = "TOAST_ACTION";
public static final String EXTRA_ITEM = "EXTRA_ITEM";
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

    for (int i = 0; i < appWidgetIds.length; ++i) {
        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.fav_movie_widget);

        Intent intent = new Intent(context, FavMovieService.class);
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
        intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
        views.setRemoteAdapter(R.id.stack_view, intent);
        views.setEmptyView(R.id.stack_view, R.id.empty_view);

        Intent toastIntent = new Intent(context, FavMovieWidget.class);
        toastIntent.setAction(FavMovieWidget.TOAST_ACTION);
        toastIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
        toastIntent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));

        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, toastIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        views.setPendingIntentTemplate(R.id.stack_view, pendingIntent);
        appWidgetManager.updateAppWidget(appWidgetIds[i], views);
    }
}


@Override
public void onEnabled(Context context) {
    super.onEnabled(context);
}

@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 appWidgetManager = 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);
}

}

远程查看服务类：

public class FavMovieService extends RemoteViewsService {
public FavMovieService() {
}

@Override
public RemoteViewsFactory onGetViewFactory(Intent intent) {
    return new RemoteViewFactory(this.getApplicationContext(),intent);
}

@Override
public void onCreate() {
    super.onCreate();
}
}

这是我的视图工厂类：

public class RemoteViewFactory implements RemoteViewsService.RemoteViewsFactory {
private List<Bitmap> widgetItem = new ArrayList<>();
private Context context;
private int appWidgetId;
Cursor cursor;

public RemoteViewFactory(Context context, Intent intent){
    this.context = context;
    appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
            AppWidgetManager.INVALID_APPWIDGET_ID);
}
@Override
public void onCreate() {
    cursor = context.getContentResolver().query(DatabaseContract.CONTENT_URI, null, null, null, null);
}

@Override
public void onDataSetChanged() {
    final long identityToken = Binder.clearCallingIdentity();
    cursor = context.getContentResolver().query(DatabaseContract.CONTENT_URI, null, null, null, null);

    if (cursor != null && cursor.moveToFirst()) {
        do {
            String crsPoster = cursor.getString(cursor.getColumnIndexOrThrow(DatabaseContract.TableColumns.POSTER));
            try {
                Bitmap bitmap = Glide.with(context)
                        .load("http://image.tmdb.org/t/p/w92/"+crsPoster)
                        .asBitmap()
                        .error(new ColorDrawable(context.getResources().getColor(R.color.colorAccent)))
                        .into(180,250).get();
                widgetItem.add(bitmap);
            }
            catch (InterruptedException|ExecutionException e){
                Log.d("Widget Load Error","error");
            }
            cursor.moveToNext();
        }
        while (!cursor.isAfterLast());
    }

    Binder.restoreCallingIdentity(identityToken);
}

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

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

@Override
public RemoteViews getViewAt(int i) {
    Bitmap bitmap = null;
    RemoteViews rv = new RemoteViews(context.getPackageName(),
            R.layout.widget_item);
    cursor.moveToPosition(i);
    MovieItem movieItem = new MovieItem(cursor);
    try {
        bitmap = Glide.with(context)
                .load("http://image.tmdb.org/t/p/w92/"+movieItem.getMoviePoster())
                .asBitmap()
                .error(new ColorDrawable(context.getResources().getColor(R.color.colorAccent)))
                .into(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL).get();
    }catch (InterruptedException|ExecutionException e){
        Log.d("Widget Load Error","error");
    }

    rv.setImageViewBitmap(R.id.iv_poster,bitmap);

    Bundle extras = new Bundle();
    extras.putInt(FavMovieWidget.EXTRA_ITEM,i);
    Intent fillInIntent = new Intent();
    fillInIntent.putExtras(extras);
    rv.setOnClickFillInIntent(R.id.iv_poster,fillInIntent);
    return rv;
}

@Override
public RemoteViews getLoadingView() {
    return null;
}

@Override
public int getViewTypeCount() {
    return 1;
}

@Override
public long getItemId(int i) {
    return cursor.moveToPosition(i) ? cursor.getLong(0) : i;
}

@Override
public boolean hasStableIds() {
    return true;
}

}

这是小部件xml文件：

android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
    android:layout_width="match_parent"

无法单击Stackview窗口小部件并显示少量图像
