实现步骤
- 屏幕旋转功能可以让用户选择屏幕的默认方向,包括0度(竖屏)、90度(横屏)、180度(反向竖屏)和270度(反向横屏)。
- 强制应用旋转功能可以让用户强制所有应用以横屏或竖屏的方式显示,无论应用本身是否支持旋转。
- 修改都支持重启后保存哦,强制APP旋转优先级>系统方向优先级。
修改示例
DisplayRotation模块
frameworks/base/services/core/java/com/android/server/wm/DisplayRotation.java
这个模块负责处理屏幕旋转的逻辑,需要在其中添加1个系统属性:persist.sys.app.rotation,分别用于控制强制应用旋转和屏幕旋转的设置。
在rotationForOrientation()和updateOrientation()方法中,需要根据persist.sys.app.rotation的值来修改当前应用的方向,如果是force_landscape,则强制为横屏;如果是force_portrait,则强制为竖屏;否则按照应用本身的方向设置。

Settings模块
packages/apps/Settings/res/values/arrays.xml

screen_rotate_entries和screen_rotate_values分别表示屏幕旋转的显示名称和对应的值,包括0度、90度、180度和270度。

OK 到这里就全部添加完成 没有难度~
其他记录:
- 比如ForceAppRotateListPreference文件为什么要新建这个东西? 早期版本没这么麻烦
- 有个坑xxxListPreference里面的AlertDialog11+版本要用
androidx.appcompat.app.AlertDialog;
不能用早期版本的 , 如果同时导入2个包 会一直编译报错 只需保留一个就可以。
测试效果:
不管应用是否支持竖屏 , 都会被强制竖屏。
总结:
本文介绍了如何在Android系统Settings中添加屏幕旋转和强制App应用旋转的功能,以便客户可以根据项目需求调整屏幕方向。
今天的文章android设置横屏_屏幕方向管理器横屏分享到此就结束了,感谢您的阅读。
