描述

在系统状态栏的右侧添加一个自定义图标

实现步骤

framework中修改

1.定义右侧系统图标的插槽
frameworks/base/core/res/res/values/config.xml文件中内容修改如下所示，定义的图标为status_bar_custom_icon

 <string-array name="config_statusBarIcons">...<item><xliff:g id="id">@string/status_bar_custom_icon</xliff:g></item>...</string-array><string translatable="false" name="status_bar_custom_icon">custom_icon</string>

其中config_statusBarIcons中子元素的顺序表示右侧状态栏图标显示的顺序。

2.引用资源
frameworks/base/core/res/res/values/symbols.xml中添加status_bar_custom_icon，否则无法引用到该资源。

   <java-symbol type="string" name="status_bar_custom_icon" />

SystemUI中修改

1.PhoneStatusBarPolicy.java的修改
frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBarPolicy.java

2.sys_custom_icon.xml内容如下所示，这里面为了方便我使用的是蓝牙图标信息

<vector xmlns:android="http://schemas.android.com/apk/res/android"android:width="17dp"android:height="17dp"android:viewportWidth="17.0"android:viewportHeight="17.0"><groupandroid:translateY="0.5"android:translateX="0.5" ><pathandroid:pathData="M8.84,8l2.62,-2.62c0.29,-0.29 0.29,-0.75 0,-1.04L8.33,1.22L8.31,1.2c-0.3,-0.28 -0.76,-0.26 -1.03,0.04c-0.13,0.13 -0.2,0.31 -0.2,0.5v4.51L4.24,3.4c-0.29,-0.29 -0.74,-0.29 -1.03,0s-0.29,0.74 0,1.03L6.78,8l-3.56,3.56c-0.29,0.29 -0.29,0.74 0,1.03s0.74,0.29 1.03,0l2.83,-2.83v4.51c0,0.4 0.33,0.73 0.73,0.73c0.18,0 0.36,-0.07 0.5,-0.2l0.03,-0.03l3.12,-3.12c0.29,-0.29 0.29,-0.75 0,-1.04L8.84,8zM8.47,6.37V3.36l1.5,1.5L8.47,6.37zM8.47,12.63V9.62l1.5,1.5L8.47,12.63z"android:fillColor="#FFFFFF"/></group>
</vector>

这样右侧添加新图标的功能就完成了
