动态切横竖屏

有个需要切横屏阅读的需求，很简单，就只有几行代码

 mCheckBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
             }else {
                    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

                }
            }
        });
