I am making multiple Volley StringRequests.
The requestfriendlist method fetches a list of profiles related to "Naruto". The requestimagelink method fetches Images for each profile it got in the previous method result.However the reponse (imagelink) I am getting is not in order from the requestimagelink method is not in order.
For Example -
Request[1,2,3,4]
Response[2,1,4,3] or any other order.
Please help me fix this issue.

Here is how to link your profiles to their images using a hashMap:
ArrayList<String> friendlist = new ArrayList<String>();
/**
Keeps the profiles' images. Later in your arrayAdapter, where you want show thumbnail image, you must
get corresponding ImageClass from of profile with profileName. If the result is null means that the image
is not loaded yet, otherwise you can use the ImageClass object to retreive profile's image.
*/
HashMap<String, ImageClass> profile_img_Hash = new HashMap<String, ImageClass>();

{
super.onCreate(savedInstanceState);

listView = (ListView) findViewById(R.id.list);
adapter = new CustomImageAdapter(this, imageList);
listView.setAdapter(adapter);
requestfriendlist("Naruto");
}
private void requestfriendlist (String profilename)

Keep in mind, in your arrayAdapter's getView(...) method you must load profile's image right from profile_img_Hash with profile name as key like this:
ImageClass img = profile_img_Hash.get(profilename);
if(img != null){
//row's imageView.setBitmap(img.getBitmap());
}
Hope this helps.

you should be passing your url in the request "http://www.google.com"+androidID not this. And the Url urlJsonArry_local that you have mentioned above returns json object response not jsonArray, Your code and Json reponse are completely irrelavant
for the Json respone in above url
private String urlJsonArry_local = "http://www.endorecord.in/endorecord/hospitaladmin/Api/device_hospitals.php?deviceid=";
RequestQueue queue = MyVolley.getRequestQueue();

//your for loop to parse hospital array here

I have followed this tutorial.
The author directly uses the data in the callback by setting the textview within the callback. What I would like to do is populate an array with the response I'm getting from my request, and then be able to use that array elsewhere (as the response listener is an anonymous inner class, I can't figure out how to get data from it; any attempt to assign to an array inside the listener has proved fruitless.
Thanks, please bear with me as I'm still a beginner.
The listener:
JsonArrayRequest req = new JsonArrayRequest(urlJsonArry,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
try {
// Parsing json array response
// loop through each json object
jsonResponse = "";
for (int i = 0; i < response.length(); i++) {
JSONObject person = (JSONObject) response
.get(i);
String name = person.getString("name");
String email = person.getString("email");
JSONObject phone = person
.getJSONObject("phone");
String home = phone.getString("home");
String mobile = phone.getString("mobile");
jsonResponse += "Name: " + name + "\n\n";
jsonResponse += "Email: " + email + "\n\n";
jsonResponse += "Home: " + home + "\n\n";
jsonResponse += "Mobile: " + mobile + "\n\n\n";
}
txtResponse.setText(jsonResponse);
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(),
"Error: " + e.getMessage(),
Toast.LENGTH_LONG).show();
}
hidepDialog();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
Toast.makeText(getApplicationContext(),
error.getMessage(), Toast.LENGTH_SHORT).show();
hidepDialog();
}
});
EDIT: The code below outlines the problem I'm having. I'm aware this is probably due to misunderstanding or misapplication on my part but still.
private void makeJsonArrayRequest(String url){
//ONLY WAY TO ACCESS INSIDE LISTENER IS TO MAKE FINAL
final ArrayList<String> string = new ArrayList<>();
showpDialog();
JsonArrayRequest req = new JsonArrayRequest(
url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
try {
for (int i = 0; i < response.length(); i++) {
JSONObject field = (JSONObject) response.get(i);
string.add(i, field.getString("title"));
//THIS PRINTS OUT ALL MY TITLES CORRECTLY, SHOWING THAT
//THE STRINGS ARRAY IS POPULATED IN THIS SCOPE
Log.d(AppController.TAG, string.get(i));
}
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(context,
"Error: " + e.getMessage(),
Toast.LENGTH_LONG).show();
}
hidepDialog();
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(AppController.TAG, "Error: " + error.getMessage());
Toast.makeText(context,
error.getMessage(), Toast.LENGTH_SHORT).show();
hidepDialog();
}
}
);
AppController.getInstance().addToRequestQueue(req);
//THIS CAUSES AN OUT OF BOUNDS EXCEPTION, AS IT THINKS THE ARRAY HAS NOT BEEN POPULATED
Log.d(AppController.TAG, string.get(3));
}
I think the problem is using variable string as a copy of actual string inside OnResponse(..).
Try adding static to this variable :
final static ArrayList<String> string = new ArrayList<>();
