推荐答案

我认为无法针对每个应用程序进行.指针图标图像是框架的一部分，其样式属性是内部的.

I don't think it is possible on a per-app basis. The pointer icon images are part of the framework and their style attributes are internal.

来自core/res/res/values/styles.xml:

<!-- Pointer styles -->
<style name="Pointer">
    <item name="android:pointerIconArrow">@android:drawable/pointer_arrow_icon</item>
    <item name="android:pointerIconSpotHover">@android:drawable/pointer_spot_hover_icon</item>
    <item name="android:pointerIconSpotTouch">@android:drawable/pointer_spot_touch_icon</item>
    <item name="android:pointerIconSpotAnchor">@android:drawable/pointer_spot_anchor_icon</item>
</style>

并且来自core/res/res/values/themes.xml:

<!-- Pointer style -->
<item name="pointerStyle">@android:style/Pointer</item>

由于它们是内部的，因此您将无法以自己的样式覆盖它们.

Since they are internal, you won't be able to override them in your own styles.
