20251105在荣品RD-RK3588-MID开发板的Android13系统的导航栏左右两边增加音量+-按钮

2025/11/4 20:51

缘起：有同事需要给MID的Android13系统的导航栏左右两边增加音量+-按钮。

开干吧！

RK3588/RK3566的Android13，在 最下面的菜单栏 左右 想显示 音量 + - 快捷键。【我司没有 物理音量+-按键】请问如何配置？

Android13 rk sdk默认没有配置的；你这边可以参考网上的一些教程配置

这个是这边之前给客户做过配置，你可以参考一下

你们 PRO-RK3566的buildroot有加入QT？

加入QT之后会增加功耗吗？[疑问]

请问如何关闭QT？[破涕为笑]

默认有加入qt ,是否增加功耗未测试过,可以自行测试 ； 关闭可以看发你的buildroot 配置 搜索QT 配置项修改，注意修改完删除前面output文件中已经编译过的qt

1、增加xml格式音量+-的矢量图标：

Z:\rk-android13-20250818RD-RK3588-MID\frameworks\base\packages\SystemUI\res\drawable\ic_sysbar_volume_add_button.xml
<vector xmlns:android="http://schemas.android.com/apk/res/android"

</vector>

Z:\rk-android13-20250818RD-RK3588-MID\frameworks\base\packages\SystemUI\res\drawable\ic_sysbar_volume_sub_button.xml
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="28dp"
android:height="28dp"
android:viewportWidth="24.0"

</vector>

2、音量+-的布局文件：

3、在导航栏的左右增加音量+-的图标：

<!-- Nav bar button default ordering/layout -->

修改为：
