不巧新拿的android4.0默认启动画面和正常显示旋转了180度,即为倒立的。原来是屏输出为倒的,查找得知可以做旋转:
步骤:
一:先把这个加上 然后加上属性ro.sf.hwrotation = 180
二:在init.rc脚本中添加如下内容: setprop ro.sf.hwrotation180
修改frameworks/base/services/surfaceflinger/SurfaceFlinger.cpp文件,在voidGraphicPlane::setDisplayHardware(DisplayHardware*hw)函数中添加如下内容:
case 180:
displayOrientation =ISurfaceComposer::eOrientation180;
break;
三:frameworks\base\services\java\com\android\server\wm\ScreenRotationAnimation.java
// Screenshot does NOT include rotation!
mSnapshotRotation = (SystemProperties.getInt("ro.sf.hwrotation",0)==180)?2:0;
//mSnapshotRotation = 0;
