WebView 无法加载网页 [英] WebView fails to load webpage

问题描述

我有一个 WebView 试图加载这样的网页:

I have a WebView trying to load a WebPage like this:

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_web);
    wv=(WebView)findViewById(R.id.webview);
    WebSettings ws=wv.getSettings();
    ws.setJavaScriptEnabled(true);
    wv.loadUrl("http://pro39.blutechnologies.com/crimes.aspx");
}

我已将 Internet 权限添加到清单中

I have added the internet permission to the manifest

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

然而，WebView 是空白的，它既不抛出错误也不加载网页.我如何加载这样的网页，我之前只尝试加载本地 html 文件，我想知道我是否必须做一些不同的事情.

However the WebView is blank,it neither throws an error nor loads the web-page.How do I load webpages like this,I have only tried loading local html files before and I would like to know if I have to do something different.

推荐答案

试试这样:

 mWebView.loadUrl("http://pro39.blutechnologies.com/crimes.aspx");  
 mWebView.setWebViewClient(new HelloWebViewClient());

  private class HelloWebViewClient extends WebViewClient {
  @Override
  public boolean shouldOverrideUrlLoading(WebView view, String url) {
    view.loadUrl(url);
    return true;
 }

使用此代码 .shouldOverrideUrlLoading() 不使用强制.使用此代码，请回复我此代码是否有效

Use this code .shouldOverrideUrlLoading() not use compulsary.use this code and please reply me this code work or not
