锁屏界面的旋转

StatusBarWindowManager.java,解除屏幕旋转，需要连同锁屏的旋转一起解除，否则无法解除

private void adjustScreenOrientation(State state) {

if(isBST()){

mLpChanged.screenOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;

}else{

if (state.isKeyguardShowingAndNotOccluded()) {

if (mKeyguardScreenRotation) {

mLpChanged.screenOrientation = ActivityInfo.SCREEN_ORIENTATION_USER;

} else {

mLpChanged.screenOrientation = ActivityInfo.SCREEN_ORIENTATION_NOSENSOR;

}

} else {

mLpChanged.screenOrientation = ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED;

}

关于ro.sf.hwrotation

这个值影响开机动画的方向

默认屏幕方向：

WindowManagerService

updateOrientationFromAppTokensLocked

import android.os.SystemProperties;

boolean updateOrientationFromAppTokensLocked(boolean inTransaction) {

long ident = Binder.clearCallingIdentity();

try {

//wfy

int req = getOrientationLocked();

if(isnuanyi()){

req = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;

}

if (req != mForcedAppOrientation) {

mForcedAppOrientation = req;

//send a message to Policy indicating orientation change to take

//action like disabling/enabling sensors etc.,

mPolicy.setCurrentOrientationLw(req);

if (updateRotationUncheckedLocked(inTransaction)) {

// changed

return true;

}

}

return false;

} finally {

Binder.restoreCallingIdentity(ident);

}

}

private boolean isnuanyi(){

boolean b=false;

b=SystemProperties.getBoolean("ro.rk.nuanyi",false);

return b;

}
