Unity代码切换XR Plug-in Management 内插件

 如上图，做编辑器工具时需要代码切换到Cardboard XR plugin, 代码片段如下，拿去用不谢

XRGeneralSettings androidXRSettings = XRGeneralSettingsPerBuildTarget.XRGeneralSettingsForBuildTarget(BuildTargetGroup.Android);

            if (androidXRSettings == null) 
            {
                var assignedSettings = ScriptableObject.CreateInstance() as XRManagerSettings;
                androidXRSettings.AssignedSettings = assignedSettings;
                EditorUtility.SetDirty(androidXRSettings); // Make sure this gets picked up for serialization later.
            }
      
            //取消当前选择的
            IReadOnlyList list = androidXRSettings.Manager.activeLoaders;
            int hasCount = list.Count;
            //Debug.Log(hasCount);
            for (int i = 0; i < hasCount; i++)
            {
                string nameTemp = list[0].GetType().FullName;
                Debug.Log("disable xr plug:" + nameTemp);
                XRPackageMetadataStore.RemoveLoader(androidXRSettings.Manager, nameTemp, BuildTargetGroup.Android);
            }
        
            //启用
            string loaderTypeName = "Google.XR.Cardboard.XRLoader";
            XRPackageMetadataStore.AssignLoader(androidXRSettings.Manager, loaderTypeName, BuildTargetGroup.Android);
