初学android菜鸟的一个小小的问题，求解答

Question

先上代码吧

public class MainActivity extends ListActivity {
Button update_btn=null;
private static final String url="http://192.168.191.1:8080/mp3/resources.xml";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
update_btn=(Button)findViewById(R.id.update_btn);
update_btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
new MyThread().start();
}
});
}
class MyThread extends Thread{
public void run(){
StringBuffer sb = new StringBuffer();
String line;
try {
URL urlStr = new URL(url);
HttpURLConnection urlConn = (HttpURLConnection) urlStr.openConnection();
BufferedReader buffer = new BufferedReader(new InputStreamReader(urlConn.getInputStream()));
while ((line = buffer.readLine()) != null) {sb.append(line);}
buffer.close();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
String xml=sb.toString();
Log.v("xxx","xml:"+xml);
}
}
}

为什么log中xml：是没有的，好麻烦

这样试试,也可以参考一下volley请求网络.

Toast.makeText(xml,Toast.LENGTH_SHORT).show();

volley使用：
