webview设置不弹出权限请求弹窗

Android使用WebView网页中要求获取麦克风权限，原生webView在setWebChromeClient()回调 onPermissionRequest 处理即可，不会弹窗（测试机系统9.0）

后来因为项目需要，更改为使用腾讯X5内核的WebView，权限请求时使用了原生中同样的方法，发现每次进入网页都会弹窗权限请求的弹框

 

@RequiresApi(Build.VERSION_CODES.LOLLIPOP)
            override fun onPermissionRequest(request: PermissionRequest?) {
                try {
                    //授权网页获取权限
                    request?.grant(request.resources)
                    request?.resources?.forEach {
                        if (it == "android.webkit.resource.AUDIO_CAPTURE") {
                            RxPermissions(this@WebViewFragment).request(Manifest.permission.RECORD_AUDIO)
                                .subscribe({ isAllow ->
                                    if (!isAllow) {
                                        ToastUtils.showShort("您拒绝了录音权限无法使用该功能，请在设置中打开")
                                    }
                                }, {
                                    it.printStackTrace()
                                })
                        }
                    }
                } catch (e: Exception) {
                    e.printStackTrace()
                }
            }

测试可用的解决办法是这样的（注意了嗷姐妹们！！重点在最后一个回调方法里）：

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，有什么出入的话，姐妹萌对比官方文档参考一下

 

补充:有bug遇到X5默认开启失败，还有一个原因可能是app本身未开启录音权限，需要本身有权限的前提下才能请求到网页中的权限。
