Webview URL 栏未完成 URL

Question

我有一个网页视图和一个 URL 栏以及一个进度条，但问题是，我必须写一个网站的完整地址，如“http://www.google.com/”才能打开它，这可以通过在 URL 中添加前缀来解决?如果是，那怎么办？

Answer 1

我应用了这个逻辑......希望它可以帮助你

if (!url.startsWith("https://") && !url.startsWith("http://"))
 {
      url = "http://" + url;
 }

您可以进行类似的更改...我认为它会帮助您不要编写整个 url...如果我错了，请原谅...但是我这样做了，它曾经帮助过我一次...

Answer 2

代替

if (validateUrl(url)) {
    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl(url);

    MainActivity.this.progress.setProgress(0);
}

试试这个。它帮助了我：

更新

if (validateUrl(url)) {
    webView.getSettings().setJavaScriptEnabled(true);
    HashMap<String, String> additionalHttpHeaders = new HashMap<String, String>();
    additionalHttpHeaders.put("cookie", yourCookie);
    webView.loadUrl(url, additionalHttpHeaders);
    MainActivity.this.progress.setProgress(0);
}
