Android使用WebView網頁中要求獲取麥克風許可權，原生webView在setWebChromeClient()回撥onPermissionRequest處理即可，不會彈窗（測試機系統9.0）

後來因為專案需要，更改為使用騰訊X5核心的WebView，許可權請求時使用了原生中同樣的方法，發現每次進入網頁都會彈窗許可權請求的彈框

 1 @RequiresApi(Build.VERSION_CODES.LOLLIPOP)
 2             override fun onPermissionRequest(request: PermissionRequest?) {
 3                 try
 
 {
 4                     //授權網頁獲取許可權
 5                     request?.grant(request.resources)
 6                     request?.resources?.forEach {
 7                         if (it == "android.webkit.resource.AUDIO_CAPTURE") {
 8                             RxPermissions(this@WebViewFragment).request(Manifest.permission.RECORD_AUDIO)
 
 9                                 .subscribe({ isAllow ->
10                                     if (!isAllow) {
11                                         ToastUtils.showShort("您拒絕了錄音許可權無法使用該功能，請在設定中開啟")
12                                     }
13                                 }, {
14                                     it.printStackTrace()
 
15                                 })
16                         }
17                     }
18                 } catch (e: Exception) {
19                     e.printStackTrace()
20                 }
21             }

測試可用的解決辦法是這樣的（注意了嗷姐妹們！！重點在最後一個回撥方法裡）：

webView.webChromeClientExtension = object : IX5WebChromeClientExtension {
            override fun getX5WebChromeClientInstance(): Any? {
                return null
            }

            override fun getVideoLoadingProgressView(): View? {
                return null
            }

            override fun onAllMetaDataFinished(p0: IX5WebViewExtension?,p1: HashMap<String, String>?) {}

            override fun onBackforwardFinished(p0: Int) {}

            override fun onHitTestResultForPluginFinished(p0: IX5WebViewExtension?,p1: IX5WebViewBase.HitTestResult?,p2: Bundle?) { }

            override fun onHitTestResultFinished(p0: IX5WebViewExtension?,p1: IX5WebViewBase.HitTestResult?) {}

            override fun onPromptScaleSaved(p0: IX5WebViewExtension?) { }

            override fun onPromptNotScalable(p0: IX5WebViewExtension?) {}

            override fun onAddFavorite(p0: IX5WebViewExtension?,p1: String?,p2: String?,p3: JsResult?): Boolean {
                return false
            }

            override fun onPrepareX5ReadPageDataFinished(p0: IX5WebViewExtension?,p1: HashMap<String, String>?) {}

            override fun onSavePassword(p0: String?,p1: String?,p2: String?,p3: Boolean,p4: Message?): Boolean {
                return false
            }

            override fun onSavePassword(p0: ValueCallback<String>?,p1: String?,p2: String?,p3: String?,p4: String?,p5: String?,p6: Boolean): Boolean {
                return false
            }

            override fun onX5ReadModeAvailableChecked(p0: HashMap<String, String>?) { }

            override fun addFlashView(p0: View?, p1: ViewGroup.LayoutParams?) { }

            override fun h5videoRequestFullScreen(p0: String?) {}

            override fun h5videoExitFullScreen(p0: String?) { }

            override fun requestFullScreenFlash() {}

            override fun exitFullScreenFlash() {}

            override fun jsRequestFullScreen() {}

            override fun jsExitFullScreen() {}

            override fun acquireWakeLock() {}

            override fun releaseWakeLock() {}

            override fun getApplicationContex(): Context? {
                return null
            }

            override fun onPageNotResponding(p0: Runnable?): Boolean {
                return false
            }

            override fun onMiscCallBack(p0: String?, p1: Bundle?): Any? {
                return null
            }

            override fun openFileChooser(p0: ValueCallback<Array<Uri>>?, p1: String?, p2: String?) { }

            override fun onPrintPage() { }

            override fun onColorModeChanged(p0: Long) {}

            override fun onPermissionRequest(s: String?,p1: Long,mediaAccessPermissionsCallback: MediaAccessPermissionsCallback?): Boolean {
                mediaAccessPermissionsCallback?.invoke(s,MediaAccessPermissionsCallback.ALLOW_AUDIO_CAPTURE,true)
                return true
            }

        }

以上，就OKK了，有什麼出入的話，姐妹萌對比官方文件參考一下
