如果下面两种设置都不起作用

 方法1.  <activity android:name=".activity.main.uniapp.modify.ModifyUniActivity"
            android:screenOrientation="portrait"/>
 方法2.  setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

那直接在activity中设置

    @Override
    public void setRequestedOrientation(int requestedOrientation) {
        super.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }
