    //打开横竖屏切换
    public void enable(){
        this.portOrientationListener.enable();
        this.landOrientationListener.enable();
    }
}

使用方法：

在Activity开启

MySensorHelper mySensorHelper=new MySensorHelper(this);



点击事件 切换到需要横竖屏切换的fragment处开启其它fragment关闭

Manifest处设置为强制竖屏

theme表示不切换横竖屏不重新创建页面

这是写在碎片中横竖屏的监听
