Android Webview文件和相机上传-Kotlin

如何解决Android Webview文件和相机上传-Kotlin

我尝试了this，还测试了this代码。如果我需要从文件浏览器上载，那么两者都可以正常工作，但是我需要选择在文件浏览器还是相机之间进行选择。

我可以找到很多Java示例来执行此操作，但是我找不到使用Kotlin完成的工作版本。以下是用于Webview文件上传器的my current code：

onActivityResult：

        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
        {
            if(requestCode == REQUEST_SELECT_FILE){
                if(uploadMessage != null){
                    uploadMessage?.onReceiveValue(WebChromeClient.FileChooserParams.parseResult(resultCode,data))
                    uploadMessage = null
                }
            }
        }else if(requestCode == FILECHOOSER_RESULTCODE){
            if(mUploadMessage!=null){
                var result = data?.data
                mUploadMessage?.onReceiveValue(result)
                mUploadMessage = null
            }
        }else{
            Toast.makeText(this,"Failed to open file uploader,please check app permissions.",Toast.LENGTH_LONG).show()
            super.onActivityResult(requestCode,resultCode,data)
        }

setWebChromeClient：

 // For 3.0+ Devices (Start)
            // onActivityResult attached before constructor
            fun openFileChooser(uploadMsg : ValueCallback<Uri>,acceptType:String) {
                mUploadMessage = uploadMsg
                val i = Intent(Intent.ACTION_GET_CONTENT)
                i.addCategory(Intent.CATEGORY_OPENABLE)
                i.type = "*/*"
                startActivityForResult(Intent.createChooser(i,"File browser"),FILECHOOSER_RESULTCODE)
            }

            // For Lollipop 5.0+ Devices
            override fun onShowFileChooser(mWebView:WebView,filePathCallback:ValueCallback<Array<Uri>>,fileChooserParams:WebChromeClient.FileChooserParams):Boolean {
                if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
                    if (uploadMessage != null) {
                        uploadMessage?.onReceiveValue(null)
                        uploadMessage = null
                    }
                    uploadMessage = filePathCallback
                    val intent = fileChooserParams.createIntent()
                    try {
                        startActivityForResult(intent,REQUEST_SELECT_FILE)
                    } catch (e:ActivityNotFoundException) {
                        uploadMessage = null
                        Toast.makeText(getApplicationContext(),"Cannot Open File Chooser",Toast.LENGTH_LONG).show()
                        return false
                    }
                    return true
                }else{
                    return false
                }
            }

            //For Android 4.1 only
            fun openFileChooser(uploadMsg:ValueCallback<Uri>,acceptType:String,capture:String) {
                mUploadMessage = uploadMsg
                val intent = Intent(Intent.ACTION_GET_CONTENT)
                intent.addCategory(Intent.CATEGORY_OPENABLE)
                intent.type = "*/*"
                startActivityForResult(Intent.createChooser(intent,FILECHOOSER_RESULTCODE)
            }

            fun openFileChooser(uploadMsg:ValueCallback<Uri>) {
                //filePermission()
                mUploadMessage = uploadMsg
                val i = Intent(Intent.ACTION_GET_CONTENT)
                i.addCategory(Intent.CATEGORY_OPENABLE)
                i.type = "*/*"
                startActivityForResult(Intent.createChooser(i,FILECHOOSER_RESULTCODE)
            }

是否有人可以通过相机或文件浏览器上传代码？

另外，文件浏览器中选择图像时的工作原理/一个储存设备本身，而是通过这种方法从谷歌驱动器上的文件，PDF文件，不正确上传。有什么想法吗？

解决方法

您可能会缺少添加下面的代码

={"Messages Sent"; ARRAYFORMULA(IFNA(VLOOKUP(B86:B145,{REGEXEXTRACT(""&Sheet1!D6:D,TEXTJOIN("|",1,B86:B145)),Sheet1!F6:F*1},2,0)))}

Here我已经详细给出了答案。希望这会帮助你。如果您有任何疑问，请通知我。

全局声明以下变量

webview.getSettings().setDomStorageEnabled(true);
webview.getSettings().setAllowContentAccess(true);
webview.getSettings().setAllowFileAccess(true);

科林代码：

var requiredPermissions = arrayOf<String>(Permissions.CAMERA,Permissions.WRITE_EXTERNAL_STORAGE,Permissions.READ_EXTERNAL_STORAGE/*,Permissions.WRITE_SETTINGS*/)

val REQUEST_SELECT_FILE = 100
private val FILECHOOSER_RESULTCODE = 1
var uploadMessage: ValueCallback<Array<Uri>>? = null

var link: String? = null
private var mUploadMessage: ValueCallback<*>? = null
