使用uts插件编写的原生弹窗view，没法插入uvue组件

分类：uni-app x

原生view控件

class PopupLayer extends DialogFragment {  
    private contentView : ViewGroup | null = null  

    constructor() {  
        super()  
    }  

    setContentView(view : ViewGroup) {  
        this.contentView = view  
    }  

    override onCreateDialog(savedInstanceState : Bundle | null) : Dialog {  
        const dialog = super.onCreateDialog(savedInstanceState)  
        dialog.window?.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT))  
        dialog.setCanceledOnTouchOutside(false)  
        dialog.setOnKeyListener((dialog : DialogInterface, keyCode : number, event : KeyEvent) : boolean => {  
            if (keyCode === KeyEvent.KEYCODE_BACK) {  
                this.dismiss()  
                return true  
            }  
            return false  
        })  
        return dialog  
    }  

    override onCreateView(inflater : LayoutInflater, container : ViewGroup | null, savedInstanceState : Bundle | null) : View {  
        const contentView = this.contentView  
        if (contentView !== null) {  
            return contentView  
        }  
        // 如果没有设置contentView,返回一个空的FrameLayout  
        return new FrameLayout(this.requireContext())  
    }  

    override onStart() {  
        super.onStart()  
        this.dialog?.window?.setLayout(  
            LayoutParams.MATCH_PARENT,  
            LayoutParams.MATCH_PARENT  
        )  
    }  
}

然后我把uvue当做参数传入报错：

原生api : DialogFragment 的用法问题，参考一下 https://blog.csdn.net/yztbydh/article/details/86502133

不好意思，忘记贴调用的代码：

showPopup(component : ViewGroup) : void {

const activity = UTSAndroid.getUniActivity() as FragmentActivity

if (activity == null) {

console.error("Unable to get UniActivity")

return

}

    UTSAndroid.getDispatcher("main").async(function (_) {  

        try {  

            const popupLayer = new PopupLayer()  

            popupLayer.setContentView(component)  

            popupLayer.show(activity.supportFragmentManager, "PopupLayer")  

            this.popupInstance = popupLayer  

        } catch (error) {  

            console.error("Error showing popup:", error)  

        }  

    })  

}

调用：

const show = () => {

const viewElement = uni.getElementById('appp')

const viewGroup = viewElement?.getAndroidView<ViewGroup>()!

console.log('viewGroup', viewGroup)

showPopup(viewGroup)

isPopupVisible.value = true

}

我直接把<template>里面的传进去就报错，和你给我发的案例不一样
