我有一个webview和一个URL栏以及一个进度条但问题是,我必须写一个像“http://www.google.com/”这样的网站的完整地址来打开它可以通过添加前缀来解决网址?如果是,那怎么样?

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;
}
你可以做出类似的改变...我认为它会帮助你不要写整个网址...对不起,如果我错了..但我这样做了,它曾帮助过我一次......

而不是
if (validateUrl(url)) {
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
MainActivity.this.progress.setProgress(0);
}
试试这个。它帮助了我:
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);
}
