推荐答案

我对 Android 不是很有经验，但我认为你可以在 "data esvalues hemes 中找到你想要的东西.xml".

I'm not that experienced with Android, but I think you can find what you're looking for in "data esvalues hemes.xml".

如果您在该文件中搜索 "selectableItemBackground"，您应该找到以下内容:

If you search in that file for "selectableItemBackground", you should find the following:

<style name="Theme">
...
        <item name="selectableItemBackground">@android:drawable/item_background</item>
...
</style>

您还可以找到 Theme.Holo.Light 和 Theme.Holo 的相应条目.*"item_background"*、*"item_background_holo_light"* 和 *"item_background_holo_dark"* 可绘制对象将位于 "data esdrawable" 文件夹中.

You'll also find respective entries for Theme.Holo.Light and Theme.Holo. The *"item_background"*, *"item_background_holo_light"*, and *"item_background_holo_dark"* drawables would be located in the "data esdrawable" folder.
