android - 我无法在 kotlin webview 中上传图片、视频和文件

Question

我可以选择视频和图片，但无法在我的 webview 、kotlin 程序中上传。

webview.setWebChromeClient(object:WebChromeClient() {
                override fun onShowFileChooser(webView:WebView, filePathCallback:ValueCallback<Array<Uri>>, fileChooserParams:FileChooserParams):Boolean {
                    var mFilePathCallback = filePathCallback
                    val intent = Intent(Intent.ACTION_GET_CONTENT)
                    intent.setType("*/*")
                    val PICKFILE_REQUEST_CODE = 100
                    startActivityForResult(intent, PICKFILE_REQUEST_CODE)
                    return true
                }
            })

            fun onActivityResult(requestCode: Int, resultCode: Int,
                                 intent: Intent,
                                 mFilePathCallback: Any): Boolean {
                var PICKFILE_REQUEST_CODE = null
                if (requestCode == PICKFILE_REQUEST_CODE)
                {
                    val result = if (intent == null || resultCode != RESULT_OK)
                        null
                    else
                        intent.getData()
                    val resultsArray = arrayOfNulls<Uri>(1)
                    resultsArray[0] = result
                    mFilePathCallback.onReceiveValue(resultsArray)

                }
                return true
            }

你需要添加到你的@Override onActivityResult

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
  if (requestCode == REQUEST_SELECT_FILE) {
        if (null == uploadMessage) {
            return
        }
        uploadMessage?.onReceiveValue(WebChromeClient.FileChooserParams.parseResult(resultCode,data))
        uploadMessage = null

    }
}

但不在您的“webview.setWebChromeClient(object:WebChromeClient()”) 内部，他不会覆盖。
