android關機充電

① Android關機充電時，充電的動畫和背景方框有錯位，要怎樣調整

Android 5.0/5.1(MTK6752 MTK6795)
充電動畫位置
bootable\bootloader\lk\dev\logo

MTK6795 MTK6752修改 動畫錯位文件
vendor\mediatek\proprietary\external\libshowlogo

有些時候你的解析度並非 {project}/ProjectConfig.mk裡面的解析度

如 LCM_WIDTH = 480
LCM_HEIGHT = 800
BOOT_LOGO = wvga
所以應該看看具體解析度，對應的那個，或者每個解析度修改一下，最好判斷對應的到底是那個解析度
cust_display.h修改對應的解析度

[Solution]
1，充電圖標的圖片都在alps/mediatek/custom/common/uboot/logo目錄下，在這里可以看到各種size的圖片的目錄
2，請將alps/mediatek/config/${project}/ProjectConfig.mk里如下部分根據實際情況作相應的修改
例如：
LCM_WIDTH = 480
LCM_HEIGHT = 800
BOOT_LOGO = wvga
3，選用不同size的LCD，需要去調整關機充電時電池圖標的坐標，請在alps/mediatek/custom/${project}/uboot/inc/cust_display.h里，調整如下設置，
#define BAR_LEFT (215)
#define BAR_TOP (156)
#define BAR_RIGHT (265)
#define BAR_BOTTOM (278)
可以用windows的畫圖軟體打開第1點里提到的圖片，根據電池邊框的像素來調整。
這里坐標的參考原點是左上角，背景圖片的左上角是(0,0)，這四個值都是相對於左上角的坐標來確定的，因此RIGHT > LEFT，BOTTOM > TOP
小技巧：1)打開畫圖軟體，選擇 查看->縮放->自定義，將圖片放到到800%
2)選擇 查看->縮放->顯示網格
這樣就可以看到一個一個的像素

② Android系統的手機是關機充電好還是開機充電好

開機和關機充電區別不大。有的智能手機還不支持關機充電功能。

區別：1、關機充電時除了充電控製程序外沒有其他程序運行，電量損耗近乎為零，所以充電速度會比開機充快。根據個人的使用經驗，開機充電，在用充電軟體的情況下，充電時間會很長。至少充電軟體顯示的時間會很長。這個時候，如果關機充一段時間，再開機，你會發現充電速度快了很多。
2、關機的話，不方面接聽外來電話。
還有一點，在使用鋰電池手機時完全不用擔心充電次數過多而損失了電池容量。另外雖然現在很多手機有防過充，但也不要長時間的連續充電，長時間的額外充電加快電池的損耗速度。同時不要使用市場上所謂的萬能充充電，由於用它充電時電壓不穩會摧毀你的手機電池，縮短壽命。

③ android 關機充電動畫怎麼實現的，求大神賜

這個是可以改的， RE管理器進入system/res/images目錄，裡面的圖片就是關機充電是的圖片，你找幾張自己喜歡的，大小相近、格式相同的圖片替換掉，然後把每張圖片的許可權修改（許可權第一列全部打勾，第二列第一個打勾，第三列不打勾）了就可以了。 我是u880的機子，不同安卓機可能路勁不一樣，你自己到system下找就是了。
