Retrieving files on Parse - Images

Question

Hi,

I have already managed to store image files into parse. My question lies in retrieving it. In the sense that in the registration process users are asked to upload a profile picture, and where the image is later stored into parse as an image. My issue lies in retrieving it, where along with pulling information like name, headline, age for a potential match, I also want to be able to retrieve the picture.

Below is the code, where I retrieve string information, but where I would want to retrieve files as well.

public class MatchingActivity extends Activity {

 private String currentUserId;
    private ArrayAdapter<String> namesArrayAdapter;
    private ArrayList<String> names;
    private ListView usersListView;
    private Button logoutButton;
    String userGender = ParseUser.getCurrentUser().getString("Gender");
    String activityName = ParseUser.getCurrentUser().getString("ActivityName");
    Number maxDistance = ParseUser.getCurrentUser().getNumber("Maximum_Distance");


    String userLookingGender = ParseUser.getCurrentUser().getString("Looking_Gender");
    Number minimumAge = ParseUser.getCurrentUser().getNumber("Minimum_Age");
    Number maximumAge = ParseUser.getCurrentUser().getNumber("Maximum_Age");
    Number userage = ParseUser.getCurrentUser().getNumber("Age");



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.matching);

        logoutButton = (Button) findViewById(R.id.logoutButton);
        logoutButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                ParseUser.logOut();
                Intent intent = new Intent(getApplicationContext(), LoginActivity.class);
                startActivity(intent);
            }
        });

        setConversationsList();
    }
    private void setConversationsList() {
        currentUserId = ParseUser.getCurrentUser().getObjectId();
        names = new ArrayList<String>();
      // String userActivitySelectionName = null;

           ParseQuery<ParseUser> query = ParseUser.getQuery();

         //  query.whereEqualTo("ActivityName",userActivitySelectionName);

           query.whereNotEqualTo("objectId", ParseUser.getCurrentUser().getObjectId());
           // users with Gender = currentUser.Looking_Gender
           query.whereEqualTo("Gender", userLookingGender);
           // users with Looking_Gender = currentUser.Gender
           query.whereEqualTo("Looking_Gender", userGender);
           query.setLimit(1);
           query.whereEqualTo("ActivityName", activityName);
           query.whereGreaterThanOrEqualTo("Minimum_Age", minimumAge).whereGreaterThanOrEqualTo("Age", userage);
           query.whereLessThanOrEqualTo("Maximum_Age", maximumAge).whereLessThanOrEqualTo("Age", userage);
  //  query.whereWithinKilometers("Maximum_Distance", point, maxDistance)





        query.findInBackground(new FindCallback<ParseUser>() {

            public void done(List<ParseUser> userList, ParseException e) {
                if (e == null) {
                    for (int i=0; i<userList.size(); i++) {
                        names.add(userList.get(i).get("Name").toString());
                        names.add(userList.get(i).get("Headline").toString());
                        names.add(userList.get(i).get("Age").toString());

                 //       names.add(userList.get(i).getParseObject("ProfilePicture").;


                    }




                    usersListView = (ListView)findViewById(R.id.usersListView);
                    namesArrayAdapter =
                        new ArrayAdapter<String>(getApplicationContext(),
                            R.layout.user_list_item, names);
                    usersListView.setAdapter(namesArrayAdapter);

                    usersListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                        @Override
                        public void onItemClick(AdapterView<?> a, View v, int i, long l) {
                            openConversation(names, i);
                        }
                    });

                } else {
                    Toast.makeText(getApplicationContext(),
                        "Error loading user list",
                            Toast.LENGTH_LONG).show();
                }
            }
        });
    }

    public void openConversation(ArrayList<String> names, int pos) {
        ParseQuery<ParseUser> query = ParseUser.getQuery();
        query.whereEqualTo("Name", names.get(pos));
        query.findInBackground(new FindCallback<ParseUser>() {
           public void done(List<ParseUser> user, ParseException e) {
               if (e == null) {
                   Intent intent = new Intent(getApplicationContext(), MessagingActivity.class);
                   intent.putExtra("RECIPIENT_ID", user.get(0).getObjectId());
                   startActivity(intent);
               } else {
                   Toast.makeText(getApplicationContext(),
                       "Error finding that user",
                           Toast.LENGTH_SHORT).show();
               }
           }
        });
    }
}

If you have any question, if like it.
