多个 Android Widget 实例仅更新最后一个小部件 [英] Multiple Android Widget instances only updating last widget
本文介绍了多个 Android Widget 实例仅更新最后一个小部件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我尝试使用此链接
更新-我发现未决意图的设置器有问题-每次单击图像视图时-意图都会发送最后定义的小部件的外部详细信息-这意味着在预添加的小部件上定义的其他待处理意图被较新的小部件运行
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
我有一个显示用户选择的图片的应用小部件.(许多小部件 - 许多图片)我的问题是:无论我按下屏幕上的哪个小部件 - 只有最后添加的小部件会更新:这是我的代码
I have an app widget that shows a picture chosen by the user.(many widgets- many pictures) my problem is: no matter which widget on screen I press - only the last added widget gets updated: here is my code

我的经理代码

String s = getString(context, key, "");
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);
}
推荐答案
问题不是你的configActivity，问题是你的widgetProvider.我遇到了和你一样的问题，但使用 链接解决了 你指定的.您需要在 buildRemoteView 中为您的 configIntent 设置被黑"意图.
The problem isn't your configActivity, the problem is in your widgetProvider. I had the same problem as you did but solved using the link you specified. You need to set the "hacked" intent on your configIntent in buildRemoteView.
