如何去实现一种android横竖屏坐标转换设计呢

引导logo的横屏
和boot logo 显示的bmp图片同名是u-mp图片的同名logo
：最后如果要保留中的一张
图片，可以只要，一张就只有一张。
内核后需要在android根
目录下执行。/mkimage.sh则重新打包写入boot.img。打包后烧录效果rockdev下面的boot.img，即可查看。若烧录内核下
的boot.img，设备无法正常引导。/
引导动画屏
设备修改 BOOTSH_UTDOWN_ANIMATION_RINGING ?=真
制作资源图片横屏/引导动画.zip 复制到设备的引导/引导动画/bootshutdown /bootanimation(源码路径),
编译结束后会复制到out下odm/media中，烧写zip可以在
Android应用层显示横屏
devicerockchiprk3326BoardConfig.mk中增加修改SF_PRIMARY_DISPLAY_ORIENTATION := 90
搜索SF_PRIMARY_DISPLAY_ORIENTATION的文件，根据项目名称修改位置
./rockchip/common/device.mk:ifneq ($(filter 90 180 270, $(strip $(SF_PRIMARY_DISPLAY_ORIENTATION))), )
. mk:ro.surface_flinger.primary_display_orientation=ORIENTATION_$(SF_PRIMARY_DISPLAY_ORIENTATION)
./rockchip/common/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION ?= 0
./rockchip/rk3368/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION := 0
./rockchip/rk3326/BoardConfig. :SF_PRIMARY_DISPLAY_ORIENTATION := 0
./rockchip/rk3126c/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION := 0
./rockchip/rk3399/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION := 0
./rockchip/rk3368a/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION
交换 xy 坐标实现旋转
gtp_x2y：x、y交换方向
镜像：x方向坐标gtp_y_reverse
：方向不镜像

RecoveryUI 横屏
