Android 11强制所有应用横屏展示
1、打开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);这一行，注释掉该行并添加如下代码：// 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、打开frameworks/base/core/java/android/app/Activity.java文件，对setRequestedOrientation方法进行如下修改： /**
* 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
}
}
