android中访问 webView加载URL时的response数据

不多说直接上代码：

1、activity 的onCreate 方法，从布局中得到WebView引用，并设置相关参数

@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    webView = (WebView) findViewById(R.id.web_view);    webView.loadUrl("http://www.baidu.com");    webView.setWebViewClient(new MyWebViewClient());    webView.setWebChromeClient(new WebChromeClient());}

2、MyWebViewClient 继承WebViewClient，并重写public boolean shouldOverrideUrlLoading(WebView view, String url)方法。简单的说就是，通过HttpClient 来请求URL，获取到相应的response，从response中就可以得到所有你想要的数据了；当然，要通过WebView.loadData()方法将response的entity加载到WebView中，这样控件才能显示web页面：

private class MyWebViewClient extends WebViewClient {    @Override    public boolean shouldOverrideUrlLoading(WebView view, String url) {        Log.d("info", "===>>> shouldOverrideUrlLoading method is called!");        // TODO Auto-generated method stub        URL local_url;        URLConnection connection;        try {            local_url = new URL(url);            connection = local_url.openConnection();            connection.setConnectTimeout(15000);            connection.connect();        } catch (Exception e) {}        final HttpGet httpGet = new HttpGet(url);        Thread theard = new Thread(new Runnable() {            @Override            public void run() {                // TODO Auto-generated method stub                try {                    HttpResponse response;                    String htmlContent;                    HttpClient httpClient = new DefaultHttpClient();                    response = httpClient.execute(httpGet);                    if (response.getStatusLine().getStatusCode() == 200) {                        Header[] headers = response.getAllHeaders();                        for (Header header : headers) {                            String name = header.getName();                            String value = header.getValue();                            Log.d("info", "===>>> name:" + name);                            Log.d("info", "===>>> value:" + value);                        }                        HttpEntity entity = response.getEntity();                        if (entity != null) {                            InputStream inputStream = entity.getContent();                            htmlContent = convertToString(inputStream);                            Log.d("info", "===>>> htmlContent:" + htmlContent);                            webView.loadData(htmlContent, "text/html", "utf-8");                        }                    }                } catch (Exception e) {                };            }        });        theard.start();

// view.loadData(htmlContent, “text/html”, “utf-8”);

        return true;        // return super.shouldOverrideUrlLoading(view, url);    }    public String convertToString(InputStream inputStream) {        StringBuffer string = new StringBuffer();        BufferedReader reader = new BufferedReader(new InputStreamReader(                inputStream));        String line;        try {            while ((line = reader.readLine()) != null) {                string.append(line + "\n");            }        } catch (IOException e) {        }        return string.toString();    }}
