上面是更新充电指示灯的状态， mBatteryLight.setColor(mBatteryFullARGB)是设置指示灯颜色

mBatteryLowARGB：低电量颜色，也是低电量警告颜色

mBatteryMediumARGB：中电量颜色，一般是低电量以上到90%电量之间，充电显示此颜色

mBatteryFullARGB：满电颜色，一般是充电状态下，90%到100%之间显示此颜色

mBatteryLight.setFlashing(mBatteryLowARGB, Light.LIGHT_FLASH_TIMED,
mBatteryLedOn, mBatteryLedOff);此方法是低电量，闪灯状态，闪灯警告
