您code是看起来不完整的：
试试这个片断：
字符串serverResponse =; //将举办由服务器返回的响应
尝试
{
HttpClient的HTTP =新DefaultHttpClient（）;
HTTPGET HTTPGET =新HTTPGET（
http://10.0.2.2:8084/SampleWebUser/SampleUser?hello=hi）;
HTT presponse响应= http.execute（HTTPGET）;
serverResponse = EntityUtils.toString（resEntity）; //服务器响应
/ *
在这里做你的其他的东西。
* /
}
赶上（例外前）
{
ex.printStackTrace（）;
}

output.setText(result);

Your code is looks incomplete:
try this snippet:
String serverResponse =""; // it will hold the response returned by the server
try
{
HttpClient http=new DefaultHttpClient();
HttpGet httpget = new HttpGet(
"http://10.0.2.2:8084/SampleWebUser/SampleUser?hello=hi");
HttpResponse response = http.execute(httpget);
serverResponse = EntityUtils.toString(resEntity); // Server response
/*
Do your other stuff here.
*/
}
catch(Exception ex)
{
ex.printStackTrace();
}
