android - 多个 Android Widget 实例只更新最后一个 widget

Question

我尝试使用这个 link 解决我的问题

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，可以显示用户选择的图片。(很多小部件 - 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才会更新:这是我的代码

我的小部件 xml 提供程序代码

<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
    android:initialLayout="@layout/widget_Test"

问题不在于您的 configActivity，而在于您的 widgetProvider。我遇到了和你一样的问题，但使用 link 解决了你指定的。您需要在 buildRemoteView 的 configIntent 上设置“hacked” Intent 。
