一、配置权限

<uses-permission android:name="android.permission.INTERNET" />

二、配置WebView

webView.webViewClient = object : WebViewClient() {
    override fun shouldOverrideUrlLoading(
        view: WebView?,
        request: WebResourceRequest?
    ): Boolean {
        view?.let {
            it.loadUrl(request?.url.toString())
            return true
        }
        return super.shouldOverrideUrlLoading(view, request)

    }
}
val webSettings = webView.settings
webSettings.apply {
    loadWithOverviewMode = true
    builtInZoomControls = true
    javaScriptEnabled = true
    useWideViewPort = true
    setSupportZoom(true)
    javaScriptCanOpenWindowsAutomatically = true
    cacheMode = WebSettings.LOAD_DEFAULT
    mixedContentMode = WebSettings.MIXED_CONTENT_ALWAYS_ALLOW
    setGeolocationEnabled(true)
    domStorageEnabled = true
    databaseEnabled = true
    useWideViewPort = true
    allowFileAccess = true
    loadWithOverviewMode = true
    pluginState = WebSettings.PluginState.ON
    cacheMode = WebSettings.LOAD_CACHE_ELSE_NETWORK
}

三、处理问题

因为链接里边需要播放的视频是http链接，而Android9以上系统默认停用明文流量。
Android9或者更高版本

    <base-config cleartextTrafficPermitted="false">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
    

Android7到Android8.1版本

    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
    

Android6.0及更低版本

    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
            <certificates src="user" />
        </trust-anchors>
    </base-config> 

我们需要在res下新建一个xml文件夹，注意命名

image.png

然后在文件中添加以下配置：

<?xml version="1.0" encoding="utf-8"?>
<network-security-config xmlns:android="http://schemas.android.com/apk/res/android">ø
    <base-config cleartextTrafficPermitted="true" />
</network-security-config>

然后在AndroidManifest里边配置:

<application
        ...
        android:usesCleartextTraffic="true"
        android:networkSecurityConfig="@xml/network_security_config">
        ...
<application>
