Question

我一直试图让TextView工作以从网址显示我的HTML，但我见过的所有例子都使用字符串，例如

String htmltext = "<h2>Title</h2><br><p>Description here</p>";
    myTextView.setText(Html.fromHtml(htmltext));

但我想从我运行的网页上显示。如果我将 htmltext 更改为“www.example.com ，但不会显示内容。

我相信很多人会说使用webview。我看起来就像一个浏览器。

首先通过提供URL到getResponseFromUrl(String str)方法从网页获取所有内容，如下所示。然后，您就可以在TextView中显示它。

 String htmltext = getResponseFromUrl("www.example.com");
 myTextView.setText(htmltext);


 public static String getResponseFromUrl(String url) {
        HttpClient httpclient = new DefaultHttpClient(); 
        HttpGet httpget = new HttpGet(url); 
        HttpResponse response = httpclient.execute(httpget); 
        HttpEntity entity = response.getEntity(); 
        InputStream iStream = entity.getContent();
        BufferedReader reader = new BufferedReader(new InputStreamReader(iStream, "iso-8859-1"), 8);
        StringBuilder strBuilder = new StringBuilder();
        String line= null;

        while ((line= reader.readLine()) != null)
            strBuilder .append(line);

        String content = strBuilder .toString(); 

        iStream.close();

        return  content; 
        }

最后我用JSoup来完成我的任务。稍后会发布代码

new Thread(new Runnable() {

            @Override
            public void run() {
                try {

                    //get the Document object from the site. Enter the link of site you want to fetch
                    Document document = Jsoup.connect("http://www.mywebsite.com.au/message.html").get(); // this is the website string

                    //Get the text we want
                    title = document.select("h2").text().toString();
                    //set the title of text view
                    //Run this on ui thread because another thread cannot touch the views of main thread
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {

                            //set both the text views
                            titleText.setText(title);
                            titleText.setMovementMethod(new ScrollingMovementMethod());
                        }
                    });
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }).start();
    }
