如何在Android中更改滚动条的颜色? [英] How can I change the color of the scrollbar in Android?

问题描述

当前问题是我们的主题继承自Theme.AppCompat，该主题似乎具有白色滚动条，并且在白色背景上不可见. 我知道我可以使用

<item name="android:scrollbarThumbVertical">@drawable/scroll_thumb</item>

并为自定义滚动条创建形状.但我只想将其更改为较深的颜色.当我使用简单的彩色矩形形状时，它的宽度与普通滚动条的宽度不同.

这可能吗?

解决方案

好，可以为scrollbarThumbVertical项目值使用颜色，但这会改变宽度，因此我将大小设置为4dp，即

似乎与其他带有原生滚动条的视图相同

    <item name="android:scrollbarSize">4dp</item>
    <item name="android:scrollbarThumbVertical">@color/scrollbar_thumb</item>

我不想设置尺寸，但是我看不到其他更干净的方法.

The current problem is that our theme is inheriting from Theme.AppCompat, which appears to have a white scrollbar, and that is not visible on the white background. I know that I can use

<item name="android:scrollbarThumbVertical">@drawable/scroll_thumb</item>

And create a shape for the custom Scrollbar. But I only want to change it to a darker color. When I use a simple colored rectangle shape, it has a different width than the normal scrollbar.

Is this possible?

解决方案

ok, it is possible to use a color for the scrollbarThumbVertical item value, but this will change the width, so I set the size to 4dp, which

seems to be the same as in the other views with the native scrollbars

    <item name="android:scrollbarSize">4dp</item>
    <item name="android:scrollbarThumbVertical">@color/scrollbar_thumb</item>

I don't like having to set the size, but I don't see any other way that would be cleaner.
