如何在android主屏幕listview小部件中加载项目？

我目前正在开发一个Android项目，它使用一个主屏幕小部件向用户显示数据。我在小部件中使用的视图是一个

列表视图

。以下是我的代码：

WidgetService类

public class WidgetService extends RemoteViewsService
{

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

}

public class WidgetProvider extends AppWidgetProvider
{   
    @Override
    public void onDeleted(Context context, int[] appWidgetIds)
    {
        super.onDeleted(context, appWidgetIds);
    }

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

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

    @Override
    public void onReceive(Context context, Intent intent)
    {
        super.onReceive(context, intent);
    }

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager,
            int[] appWidgetIds) 
    {
        for(int i=0;i<appWidgetIds.length;i++)
        {
            RemoteViews rv = new RemoteViews(context.getPackageName(),
                    R.layout.widget);

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

            rv.setRemoteAdapter(R.id.widgetListView, intent);

            appWidgetManager.updateAppWidget(appWidgetIds[i], rv);
        }
        super.onUpdate(context, appWidgetManager, appWidgetIds);
    }
}

public class WidgetRemoteViewsFactory implements RemoteViewsFactory
{
private Context context = null;
private int appWidgetId;

private List<String> widgetList = new ArrayList<String>();
private DBHelper dbhelper;

public WidgetRemoteViewsFactory(Context context, Intent intent)
{
    this.context = context;
    appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
            AppWidgetManager.INVALID_APPWIDGET_ID);
    Log.d("AppWidgetId", String.valueOf(appWidgetId));
    dbhelper = new DBHelper(this.context);
}

private void updateWidgetListView()
{
    String[] widgetFruitsArray = dbhelper.retrieveFruitsList();
    List<String> convertedToList = new ArrayList<String>(Arrays.asList(widgetFruitsArray));
    this.widgetList = convertedToList;
}

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

@Override
public long getItemId(int position)
{
    return position;
}

@Override
public RemoteViews getLoadingView()
{
    // TODO Auto-generated method stub
    return null;
}

@Override
public RemoteViews getViewAt(int position)
{
    Log.d("WidgetCreatingView", "WidgetCreatingView");
    RemoteViews remoteView = new RemoteViews(context.getPackageName(),
            R.layout.listview_row_item);

    Log.d("Loading", widgetList.get(position));
    remoteView.setTextViewText(R.id.listTV, widgetList.get(position));

    return remoteView;

对于（int i=0；i我发现了这个问题。结果是，我需要返回
getViewTypeCount（）中的视图数，其中我的大小写为1
在我的WidgetRemoteViewsFactory类中。
嗨，我也遇到了同样的问题。如果你有解决方案，你能帮助我吗。你能给我发送这个和ho的运行代码，让kist项目可以点击吗？如果你有解决方案，请帮助我。我有同样的问题，我们的代码几乎相同，但我从web服务。我将我的
getViewTypeCount
也设置为返回1，但我的
ListView
仍然不显示项目。你能帮我吗？谢谢。
