如何基于开发板RK3568 Android 11强制所有应用横屏展

RK3568 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 } }
