不读书的服务器文本 [英] Not Reading text from server

问题描述

我想读取服务器上所有的文字，我觉得我的code未检索来自服务器的文本将请你帮我，我怎么能解决这个问题，我是新来的android开发。在此先感谢

 公共类TestActivity延伸活动{

/ **第一次创建活动时调用。 * /
@覆盖
公共无效的onCreate（包savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.main）;

    TextView的电视=（TextView中）findViewById（R.id.my_text）;


                尝试 {

                    网址URL =新的URL（http://www.google.com:80/）;
                    StringBuilder的内容=新的StringBuilder（）;
                    由服务器返回//读取文本

                    的BufferedReader在=新的BufferedReader（新的InputStreamReader（url.openStream（）））;
                    串线;
                    而（（行= in.readLine（））！= NULL）{
                        content.append（行+\ N）;
                    }
                    tv.setText（content.toString（））;
                    的setContentView（电视）;

                    附寄（）;
                }

                赶上（MalformedURLException的E）{

                    的System.out.println（格式不正确的URL：+ e.getMessage（））;

                }

                赶上（IOException异常E）{

                    的System.out.println（I / O错误：+ e.getMessage（））;

                }


};


}
 

解决方案

可能是你可以尝试这样的，只是一个想法只有：

  StringBuilder的内容=新的StringBuilder（）;
                由服务器返回//读取文本
                的BufferedReader在=新的BufferedReader（新InputStreamReader的（新的URL（http://www.google.com:80/）.openConnection（）的getInputStream（）））;
                串线;
                而（（行= in.readLine（））！= NULL）{
                    content.append（行+\ N）;
                }

tv.setText（content.toString（））;
的setContentView（电视）;

public class TestActivity extends Activity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {

    setContentView(R.layout.main);

    TextView tv= (TextView)findViewById(R.id.my_text);


                try {

                    URL url = new URL("http://www.google.com:80/");
                    StringBuilder content = new StringBuilder();
                    // read text returned by server

                    BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
                    String line;
                    while ((line = in.readLine()) != null) {
                        content.append(line +"\n");
                    }
                    tv.setText(content.toString());
                    setContentView(tv);

                    in.close();
                }

                catch (MalformedURLException e) {

                    System.out.println("Malformed URL: " + e.getMessage());

                }

                catch (IOException e) {

                    System.out.println("I/O Error: " + e.getMessage());

                }


};        


}

解决方案

May be you can try like this, just a thought only :

StringBuilder content = new StringBuilder();
                // read text returned by server
                BufferedReader in = new BufferedReader(new InputStreamReader(new URL("http://www.google.com:80/").openConnection().getInputStream()));
                String line;
                while ((line = in.readLine()) != null) {
                    content.append(line +"\n");
                }

tv.setText(content.toString());
setContentView(tv);
