Android 11強制所有應用橫屏展示

1、打開

frameworks/base/core/java/android/content/pm/parsing/component/ParsedActivityUtils.java

文件，定位到

parseActivityOrReceiver

方法的

int screenOrientation = sa.getInt(R.styleable.AndroidManifestActivity_screenOrientation, SCREEN_ORIENTATION_UNSPECIFIED);

這一行，注釋掉該行并添加如下代碼：// int screenOrientation = sa.getInt(R.styleable.AndroidManifestActivity_screenOrientation, SCREEN_ORIENTATION_UNSPECIFIED);

// Edit by jgduan

int screenOrientation;

if(pkg.getSharedUserId() == null){

screenOrientation = 0;

} else {

screenOrientation = sa.getInt(R.styleable.AndroidManifestActivity_screenOrientation, SCREEN_ORIENTATION_UNSPECIFIED);

}

// End

2、

打開

frameworks/base/core/java/android/app/Activity.java

文件，對

setRequestedOrientation

方法進行如下修改：

/**

*Change the desired orientation of this activity. If the activity

* is currently in the foreground or otherwise impacting the screen

* orientation, the screen will immediately be changed (possibly causing

* the activity to be restarted). Otherwise, this will be used the next

* time the activity is visible.

*

* @param requestedOrientation An orientation constant as used in

* {@link ActivityInfo#screenOrientation ActivityInfo.screenOrientation}.

*/

public void setRequestedOrientation(@ActivityInfo.ScreenOrientation int requestedOrientation) {

if (mParent == null) {

try {

// Edit by jgduan

//ActivityTaskManager.getService().setRequestedOrientation(

// mToken, requestedOrientation);

if(mApplication != null && mApplication.getApplicationInfo() != null

&& mApplication.getApplicationInfo().uid > 10000){

ActivityTaskManager.getService().setRequestedOrientation(

mToken, ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

} else {

ActivityTaskManager.getService().setRequestedOrientation(

mToken, requestedOrientation);

}

// End

} catch (RemoteException e) {

// Empty

}

} else {

// Edit by jgduan

// mParent.setRequestedOrientation(requestedOrientation);

if(mApplication != null && mApplication.getApplicationInfo() != null

&& mApplication.getApplicationInfo().uid > 10000){

mParent.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

}else{

mParent.setRequestedOrientation(requestedOrientation);

}

// End

}

}
