private void getWeather() {
RequestQueue mQueue =
Volley.newRequestQueue(this); 
String citycode =
getIntent().getStringExtra("city_code");
String url =
"http://wthrcdn.etouch.cn/weather_mini?citykey="+citycode;
Log.d("Weather",url.toString());
JsonObjectRequest jsonObjectRequest = new
JsonObjectRequest(url, null,new Response.Listener() {
@Override
public void onResponse(JSONObject response) {
Log.d("TAG", response.toString());
Utility.handleWeatherResponse(WeatherActivity.this,
response.toString());
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("TAG", error.getMessage(), error);
}
})
{
protected Response
 parseNetworkResponse(NetworkResponse
response)
{
JSONObject jsonObject;
try {
jsonObject = new JSONObject(new
String(response.data,"UTF-8"));
return Response.success(jsonObject,
HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return Response.error(new ParseError(e));
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return Response.error(new ParseError(e));
}
}
};

mQueue.add(jsonObjectRequest);
}
