WabView 类

    public void LoadWeb() {
    webView = (WebView) findViewById(R.id.webview_test);
    webView.getSettings().setAppCacheEnabled(false);
    webView.clearCache(true);
    webView.reload();
    webView.getSettings().setJavaScriptEnabled(false);
    webView.getSettings().setLoadsImagesAutomatically(true);
        webView.loadUrl("https://www,mydomaine.com");
    swipe.setRefreshing(true);
    webView.setWebViewClient(new WebViewClient() {


        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);
        }

        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {

            webView.loadUrl("file:///android_asset/www/error.html");
        }

            //Hide the SwipeReefreshLayout

            swipe.setRefreshing(false);

        }
        public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError er) {
            handler.proceed();

明文在 android 9 中被禁用,所以你必须添加网络安全

添加 src\main\res\xml\network_security_config.xml ,内容如下:

    <?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
</network-security-config>

然后通过设置 android:networkSecurityConfig 属性在 AndroidManifest.xml 中注册策略文件。

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