Re: [android-developers] Can not resolve symbol 'JsonObjectRequest'

2017-01-09 Thread Marina Cuello 
Did you import it in your class?

import com.android.volley.toolbox.JsonObjectRequest;

The easier way is to use the menu option "Code/Optimize Imports" or the
shorcut available on your operative system.

You will also need to add the dependency to your build.gradle file:

compile 'com.android.volley:volley:1.0.0'


Or whatever is the newest version number.

[android-developers] Can not resolve symbol 'JsonObjectRequest'

2017-01-09 Thread Alex 
Hi,

I am trying to retrieve a JSON query. I am a beginner so I have copied and 
pasted the below model code from 
https://developer.android.com/training/volley/request.html. In android 
studio every JsonObjectRequest is being highlighted red with the hover-over 
error message "Can not resolve symbol 'JsonObjectRequest'. Please can you 
tell me how to fix? Thank you

TextView mTxtDisplay;

ImageView mImageView;
mTxtDisplay = (TextView) findViewById(R.id.txtDisplay);
String url = "http://my-json-feed;;

JsonObjectRequest jsObjRequest = new JsonObjectRequest
(Request.Method.GET, url, null, new Response.Listener() {

@Override
public void onResponse(JSONObject response) {
mTxtDisplay.setText("Response: " + response.toString());
}
}, new Response.ErrorListener() {

@Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub

}
});

// Access the RequestQueue through your singleton class.
MySingleton.getInstance(this).addToRequestQueue(jsObjRequest);
