android关机充电

① Android关机充电时，充电的动画和背景方框有错位，要怎样调整

Android 5.0/5.1(MTK6752 MTK6795)
充电动画位置
bootable\bootloader\lk\dev\logo

MTK6795 MTK6752修改 动画错位文件
vendor\mediatek\proprietary\external\libshowlogo

有些时候你的分辨率并非 {project}/ProjectConfig.mk里面的分辨率

如 LCM_WIDTH = 480
LCM_HEIGHT = 800
BOOT_LOGO = wvga
所以应该看看具体分辨率，对应的那个，或者每个分辨率修改一下，最好判断对应的到底是那个分辨率
cust_display.h修改对应的分辨率

[Solution]
1，充电图标的图片都在alps/mediatek/custom/common/uboot/logo目录下，在这里可以看到各种size的图片的目录
2，请将alps/mediatek/config/${project}/ProjectConfig.mk里如下部分根据实际情况作相应的修改
例如：
LCM_WIDTH = 480
LCM_HEIGHT = 800
BOOT_LOGO = wvga
3，选用不同size的LCD，需要去调整关机充电时电池图标的坐标，请在alps/mediatek/custom/${project}/uboot/inc/cust_display.h里，调整如下设置，
#define BAR_LEFT (215)
#define BAR_TOP (156)
#define BAR_RIGHT (265)
#define BAR_BOTTOM (278)
可以用windows的画图软件打开第1点里提到的图片，根据电池边框的像素来调整。
这里坐标的参考原点是左上角，背景图片的左上角是(0,0)，这四个值都是相对于左上角的坐标来确定的，因此RIGHT > LEFT，BOTTOM > TOP
小技巧：1)打开画图软件，选择 查看->缩放->自定义，将图片放到到800%
2)选择 查看->缩放->显示网格
这样就可以看到一个一个的像素

② Android系统的手机是关机充电好还是开机充电好

开机和关机充电区别不大。有的智能手机还不支持关机充电功能。

区别：1、关机充电时除了充电控制程序外没有其他程序运行，电量损耗近乎为零，所以充电速度会比开机充快。根据个人的使用经验，开机充电，在用充电软件的情况下，充电时间会很长。至少充电软件显示的时间会很长。这个时候，如果关机充一段时间，再开机，你会发现充电速度快了很多。
2、关机的话，不方面接听外来电话。
还有一点，在使用锂电池手机时完全不用担心充电次数过多而损失了电池容量。另外虽然现在很多手机有防过充，但也不要长时间的连续充电，长时间的额外充电加快电池的损耗速度。同时不要使用市场上所谓的万能充充电，由于用它充电时电压不稳会摧毁你的手机电池，缩短寿命。

③ android 关机充电动画怎么实现的，求大神赐

这个是可以改的， RE管理器进入system/res/images目录，里面的图片就是关机充电是的图片，你找几张自己喜欢的，大小相近、格式相同的图片替换掉，然后把每张图片的权限修改（权限第一列全部打勾，第二列第一个打勾，第三列不打勾）了就可以了。 我是u880的机子，不同安卓机可能路劲不一样，你自己到system下找就是了。
