private EditText username;

private EditText url;

private Button run;

@Override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
url=(EditText) this.findViewById(R.id.edit_url);
username = (EditText) this.findViewById(R.id.username);
run = (Button) this.findViewById(R.id.button1);
run.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

AsyncHttpClient client = new AsyncHttpClient();
//传参
//Map<String,String> map=new HashMap<String,String>();//map.put("state", "ok");
//RequestParams param=new RequestParams(map);
//get方式异步发送请求，有get(url,param,handler)，post方式也差不多
client.get(url.getText().toString(),
new AsyncHttpResponseHandler() {
//错误时跳入
@Override
public void onFailure(int arg0, Header[] arg1,
byte[] arg2, Throwable arg3) {
System.out.println(arg3.getMessage());
}

//无异常时跳入
// statusCode 返回状态200正常
// headers一般都放了系统设置的信息，key-value集合存储的
//responseBody返回的信息
@Override
public void onSuccess(int statusCode,
Header[] headers, byte[] responseBody) {

if (statusCode == 200) {
for (int i = 0; i < headers.length; i++) {
Header header = headers[i];
System.out.println("header------------Name:"+ header.getName()+ ",--Value:"+ header.getValue());
}
JSONObject json = JSON.parseObject(new String(responseBody));
username.setText(json.get("user").toString());
}
}

});

}

});
