MTK平台添加高分屏兼容界面详程

来源：互联网发布：艺恩数据编辑：程序博客网时间：2024/05/19 15:19

目前的产品分辨率是320*240的屏幕，所谓的低分屏，由于有提升用户体验的需求，需要添加一批次的高分屏（480*360），因此系统在surface系统启动之前的阶段图形显示都需要做一个高低分屏的适配逻辑。

硬件平台：MTK（MT6572）

软件平台：Android 4.4.2

从业数几载，业内人士反应MTK代码超级乱的情况早有耳闻，不过百闻终将不如一见。

下面入正题，首先要把相关的bmp图片资源加入系统：

源码里边有一个bmp格式处理的工具，会将该目录下的bmp格式转化为raw模式，上述代码添加的图片为uboot，kernel第一屏界面，以及charger模式电量从1～100的百张图片。

第四步，修改bootloader首张图片的逻辑处理。之前做过调适，因为单单修改external下的该文件，bootloader阶段的第一屏图片显示不对，因此特意对bootloader中的代码做了再次处理。

自此，适配工作大功告成，不过资源文件的diff没有上传，依个人情况做改动吧。。。。。。
