t.sys.hwrotationxrd0来作为动画方向当修改系统方向时同时修改这个参数当系统启动加载动画时在根据这个来旋转动画方式以保证动画方式与系统方式一致。

实现步骤如下

一、在rk3288\device\rockchip\rk3288\system.prop

与屏幕主屏默认方式一致

二、在rk3288\frameworks\base\cmds\bootanimation\BootAnimation.cpp

内修改动画方式

SurfaceComposerClient::getDisplayInfo(dtoken,

dinfo);if

hwrotationaa[PROPERTY_VALUE_MAX];property_get(persist.sys.hwrotationxrd,hwrotationaa,0);ALOGE(hwrotation::%s

hwrotationaa);int

atoi(hwrotationaa)/90;spSurfaceControl

control

session()-createSurface(String8(BootAnimation),(orient

orient3)

session()-createSurface(String8(BootAnimation),

dinfo.w,

PIXEL_FORMAT_RGB_565);if(orient

orient

dinfo.w);mSession-setDisplayProjection(dtoken,orient,destRect,destRect);}ALOGE(eliot

BootAnimation::readyToRun22222222

add

三、在rk3288\frameworks\native\services\surfaceflinger\DisplayDevice.cpp

内初始化动画方向

Screen;break;default:mDisplayName

Virtual

property[PROPERTY_VALUE_MAX];property_get(persist.sys.hwrotationxrd,

property,

atoi(property);switch(defaultOrientation)

{case

DisplayState::eOrientationDefault;break;case

DisplayState::eOrientation90;break;case

DisplayState::eOrientation180;break;case

DisplayState::eOrientation270;break;default:defaultOrientation

DisplayState::eOrientationDefault;break;}//

initialize

transform.setProjection(defaultOrientation,

mViewport,

setProjection(DisplayState::eOrientationDefault,

mViewport,

NUM_FRAMEBUFFER_SURFACE_BUFFERSsurface-allocateBuffers();

#endif
