我正在为我的应用开发一个Widget,我遇到了一个问题:

我的android.widget.RemoteViewsService类的onGetViewFactory方法未被调用!

我的代码:

IntentService

  this.views = new RemoteViews(this.ctx.getPackageName(), i);
  Intent localIntent = new Intent(this.ctx, MyWidgetService.class);
  localIntent.putExtra("WidgetId", param);
  localIntent.setData(Uri.parse(localIntent.toUri(Intent.URI_INTENT_SCHEME)));

  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) 
  this.views.setRemoteAdapter(R.id.weather_list, localIntent);
  else
  this.views.setRemoteAdapter(param, R.id.weather_list, localIntent);

  ComponentName localComponentName = new ComponentName(this.ctx, MyWidgetProvider.class);
  AppWidgetManager localAppWidgetManager = AppWidgetManager.getInstance(this.ctx);
  localAppWidgetManager.notifyAppWidgetViewDataChanged(param, R.id.weather_list);
  localAppWidgetManager.updateAppWidget(param, this.views);

MyWidgetService

我的类扩展了RemoteViewsService并拥有此代码

@Override
    public RemoteViewsFactory onGetViewFactory(Intent intent) {
        // TODO Auto-generated method stub
        System.out.println("test");
        return null;
    }

MyWidgetProvider 我的类扩展了AppWidgetProvider

任何人都可以帮助我吗? 我的代码有什么问题?

谢谢: - )

编辑:是的,但是当我放置断点或日志时,它是相同的。

答案 0 :(得分:4)

您是否在AndroidManifest.xml宣布了服务?

<service
     android:name="com.mypackage.MyWidgetService"
     android:exported="false"
     android:permission="android.permission.BIND_REMOTEVIEWS" >
</service>
