我想在 Android Studio 中使用按钮样式 "Widget.Button.Transparent"
I would like to use the button style "Widget.Button.Transparent" in Android Studio
当我要使用这种按钮样式时,会出现此消息:
error: resource android:style/Widget.Button.Transparent is private.
关于我的系统的详细信息:
- OS:Ubuntu 16.04 LTS
- Android Studio 3.1.4 Build # AI-173.4907809,构建于 2018 年 7 月 23 日
- JRE: 1.8.0_152-release-1024-b01amd64
- JVM:JetBrains 的 OpenJDK 64 位服务器 VM s.r.o
- Linux 4.15.0-33-通用
自己做吧:
在styles.xml
(source):
<style name="Widget.Button.Transparent">
<item name="background">@drawable/btn_default_transparent</item>
<item name="textAppearance">?attr/textAppearanceSmall</item>
<item name="textColor">@color/white</item>
</style>
在您的 drawable
文件夹中的 btn_default_transparent.xml
(source):

本文中引用的可绘制对象是九个补丁的 PNG,并且位于特定于 DPI 的位置。您也许可以使用 @android:drawable/
访问它们,但如果不能,这是我可以在以下位置找到的最高密度:https://github.com/aosp-mirror/platform_frameworks_base/tree/master/core/res/res/drawable-xhdpi/.
