这里是我的代码：
的TextView txtErrorMsg;
private class MyAsyncTask extends AsyncTask<String, String, JSONObject> {
JSONObject json;
@Override
protected JSONObject doInBackground(String... params) {
String host = "my_url";
GamerFunctions gamerFunction = new GamerFunctions();
HttpParams httpParams = new BasicHttpParams();
int timeout = 100;
HttpConnectionParams.setConnectionTimeout(httpParams, timeout);
HttpConnectionParams.setSoTimeout(httpParams, timeout);
HttpClient client = new DefaultHttpClient(httpParams);
try {
HttpGet request = new HttpGet(new URI(host));
HttpResponse response = client.execute(request);
StatusLine status = response.getStatusLine();
if (status.getStatusCode() == HttpStatus.SC_OK) {
if (params.length != 3)
return null;
json = gamerFunction.addNewGamer(params[0], params[1],
params[2]);
} else {
// update ui thread
}
} catch (ClientProtocolException e) {
e.printStackTrace();
// txtErrorMsg.setText("timeout!!!");
} catch (IOException e) {
e.printStackTrace();
// txtErrorMsg.setText("timeout!!!");
} catch (URISyntaxException e) {

e.printStackTrace();
}
return json;
}
}
