update – I figured out that there is something wrong with the setter of the pending intent- every time I click on the imagevIEw- the intent sends the extre details of the last defined Widget-
meaning that the other pending intents that where defined on the pre-added Widgets were run-over by the newer Widgets

我有一个应用程序小部件,显示用户选择的图片.(许多小部件 – 许多图片)
我的问题是：无论我在屏幕上显示哪个小部件 – 只有最后添加的小部件会更新：
这是我的代码

我的Mngr代码

public voID updateTestWidget(Context context,RemoteVIEws remoteVIEws){    String key = context.getString(R.string.TestWidget_string) + "_"            + AppWidgetManager.EXTRA_APPWidget_ID;    String s = getString(context,"");    if (s != null && s.equals("") == false)    {        int resID = Integer.valueOf(s);        remoteVIEws.setimageVIEwResource(R.ID.TestWIDgetimage,resID);    }}public voID pushUpdate(RemoteVIEws remoteVIEw,Context ctx,Class<?> cls){    Componentname myWidget = new Componentname(ctx,cls);    AppWidgetManager manager = AppWidgetManager.getInstance(ctx);    manager.updateAppWidget(myWidget,remoteVIEw);}

解决方法 问题不在于您的configActivity,问题出在您的WidgetProvIDer中.我遇到了和你一样的问题但是使用你指定的 link解决了.您需要在buildremoteVIEw中的configIntent上设置“Hacked”意图. 总结
