代码如下
public class Aty extends Activity {

private TextView textview;

String result;
String newss;
Handler handler = new Handler(){
@Override
public void handleMessage(Message msg){
if(msg.what==1){

                System.out.println(result);
                textview.setText(newss);
            }
        }
  };

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.other);
textview=(TextView)findViewById(R.id.text);
new Thread(new Runnable(){
Intent intent=getIntent();
int id=intent.getIntExtra("id",1);

    String[] date = {"http://schoolunify.sinaapp.com/index.php/news_c/reNewsContent_IOS",
            "news_id="+id};
    @Override
    public void run() {
        // TODO Auto-generated method stub
        URL HttpUrl;

        try {
            HttpUrl = new URL(date[0]);
            HttpURLConnection con= (HttpURLConnection)HttpUrl.openConnection();
            con.setDoInput(true);
             con.setDoOutput(true);
            con.setRequestMethod("POST");

            int responseCode = con.getResponseCode();
            if (responseCode==200) {

            OutputStreamWriter osw = new OutputStreamWriter(con.getOutputStream(),"UTF-8");
            BufferedWriter bw = new BufferedWriter(osw);
            bw.write(date[1]);
            bw.flush();

          StringBuffer sb = new StringBuffer();
        String s;
        BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
        while((s=br.readLine())!=null){
            sb.append(s);
        }
        result= sb.toString();
        osw.close();
        bw.close();
        br.close();
            }

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

}).start();
Message msg= new Message();
msg.what = 1;
handler.sendMessage(msg);

}

private void readJson(String s ) {

try {
    JSONObject obj = new JSONObject();

obj.put("content", s);
System.out.println(obj);
newss =obj.getString("content");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}
