目录 一、概述 二、电池图标显示所在源码分析 三、自定义电池图标 四、总结 一、概述 原生的电池图标是竖向，并且很小，不太美观。现客户需求状态栏的电池图标变为横放的。众所周知，状态栏的修改在SystemUI里。 效果图： 状态栏布局文件是status_bar。路径：SystemUI\res\layout\status_bar.xml ..省略部分代码..电池图标就在布局system_icons中，路径：SystemUI\res\layout\system_icons.xml 其中BatteryMeterView是自定义View，继承于LinearLayout，实现的接口有BatteryStateChangeCallback,Tunable,DarkReceiver,ConfigurationListener。主要是监听电池状态变化，白天黑夜模式，以及主题等变化。 public class BatteryMeterView extends LinearLayout implements BatteryStateChangeCallback, Tunable, DarkReceiver, ConfigurationListener {}而锁屏界面的状态栏也是引用到这个BatteryMeterView，在路径SystemUI\src\com\android\systemui\statusbar\phone\KeyguardStatusBarView.java中 private BatteryMeterView mBatteryView;OK，明白了大概的逻辑，就可以自己试着重构了。 三、自定义电池图标如果在原文件 BatteryMeterView中修改太过麻烦，所以我们可以模仿BatteryMeterView，直接自己写一个自定义View。 直接上主菜！ 1.在system_icons.xml中替换布局。 bird_status_bar_battery.xml 可以看到，上面的布局是一个横向的LinearLayout。 1.其中有outside和inside的电量百分比，百分比的显示或隐藏可以在设置-电池中去控制，也可以直接写死一种方式。 2.outside的充电图标和inside的充电图标，就是开始充电后显示的闪电图标，可以选择在电池内也可以选择在外侧。充电图标和电量百分比是对立的，如果充电图标inside，则电量百分比outside，反之亦然。 3.border是电池的边界，就是最外的一圈。 4.charge_level用list来管理，一共有10来个等级。电量的多少就是从这里体现。
2.布局中的src都是矢量图，具体的矢量图代码在另一篇文章中。可以参考一下。 传送门：http://t.csdn.cn/BgwqF 3.自定义view，BirdBatteryMeterView同样继承于LinearLayout package com.bird.systemui; import android.app.ActivityManager; import android.content.Context;
