Answer 1

final TextView mTextView = (TextView) findViewById(R.id.text); 
... 

// Instantiate the RequestQueue. 
RequestQueue queue = Volley.newRequestQueue(this); 
String url ="http://lazurd.com/shop/api/rest/custom/categories/"; 

// Request a string response from the provided URL. 
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, 
      new Response.Listener<String>() { 
    @Override 
    public void onResponse(String response) { 
     // Display the first 500 characters of the response string. 
     mTextView.setText("Response is: "+ response.substring(0,500)); 
    } 
}, new Response.ErrorListener() { 
    @Override 
    public void onErrorResponse(VolleyError error) { 
     mTextView.setText("That didn't work!"); 
    } 
}); 
// Add the request to the RequestQueue. 
queue.add(stringRequest);
