Only returns an index of -1 when there is a match

I am trying to get an index of a item in an array that is selectable in a list view. The only issue is that when i click on the item, it only returns the index of -1 which means that it doesnt match when in fact there should be a match. Thanks in advanced!

you define glimpse two times, could you try to make those changes,
List<String> glimpse;
and inside onCreate initialize it
glimpse = new ArrayList<>();
and do the same for titles and universalListings.

Try using these two sections of code. You are shadowing the member variables with local variables of the same name.
public class GlimpseListFragment extends ListFragment {
List<String> glimpse;
List<String> titles;
List<UniverseListing> universalListings;
Later...
glimpse = new ArrayList<String>();
for(UniverseListing value: universalListings){
glimpse.add(value.universeGlimpse);
}
titles = new ArrayList<String>();
for(UniverseListing value: universalListings){
titles.add(value.universeId);
}
You don't need to initialize Arraylists with the class. You should typically lazily initialize them (in other words, when you need to)

Typed this up under the wrong account (cant comment, sorry), didn't stick I guess. You create one Activity with one ListView and pass in the adapter that you want to use from the CardView intent.
Butterfly Cardview -> BUTTERFLY -> ButterflyAdapter
Baseball Bat Cardview -> BASEBALL -> BaseballBatAdatper
if your items are not related. If they are related you can use the same adapter but send in a different layout based on what you sent in.
Butterfly -> R.layout.butterfly_items
Whale -> R.layout.whale_items

How to implement onItemClickListener with a custom array adapter?

I have been searching about this issue but still I am not very clear on how to use a click listener with an array adapter.
I need a click listener for each item of the list.
Codes:
The Area item:
package fogames.tamagomonsters;
public class Area {
public String name;
public String number;
public Area(String name, String number) {
this.name = name;
this.number = number;
}
}
The array adapter:
package fogames.tamagomonsters;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.ArrayList;
public class AreasAdapter extends ArrayAdapter<Area> {
public AreasAdapter(Context context, ArrayList<Area> Areas) {
super(context, 0, Areas);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// Get the data item for this position
Area Area = getItem(position);
// Check if an existing view is being reused, otherwise inflate the view
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.item_area, parent, false);
}
// Lookup view for data population
TextView tvname = (TextView) convertView.findViewById(R.id.tvName_area);
TextView tvnumber = (TextView) convertView.findViewById(R.id.tvNumber_of_beasts);
// Populate the data into the template view using the data object
tvname.setText(Area.name);
tvnumber.setText(Area.number);
// Return the completed view to render on screen
return convertView;
}
}
The activity:
package fogames.tamagomonsters;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.graphics.Color;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.AdapterView;
import android.widget.FrameLayout;
import android.widget.ListView;
import java.util.ArrayList;
public class PlayMenuActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
FrameLayout fl = new FrameLayout(this);
fl.setBackgroundColor(Color.argb(255, 0, 0, 0));
// Construct the data source
ArrayList<Area> arrayOfAreas = new ArrayList<Area>();
// Create the adapter to convert the array to views
AreasAdapter adapter = new AreasAdapter(this, arrayOfAreas);
// Attach the adapter to a ListView
ListView lv = new ListView(this);
lv.setAdapter(adapter);
// Restore preferences
SharedPreferences prefs = getSharedPreferences(PreferenceConstants.PREFERENCE_NAME, MODE_PRIVATE);
int mlen = prefs.getInt(PreferenceConstants.MLEN, 0);
long money = prefs.getLong(PreferenceConstants.MONEY, 0);
int mall = 6; //hay que ver que hacer con esto...
int eqall = 3; //igual
boolean[] mgot = new boolean[mall];
int[] exp = new int[eqall];
int[] lvl = new int[eqall];
int[] at = new int[eqall];
int[] en = new int[eqall];
for (int i = 0; i < mall; i++) {
mgot[i] = prefs.getBoolean(PreferenceConstants.MGOT[i], false);
}
for (int i = 0; i < eqall; i++) {
exp[i] = prefs.getInt(PreferenceConstants.EXP[i], 0);
lvl[i] = prefs.getInt(PreferenceConstants.LVL[i], 0);
at[i] = prefs.getInt(PreferenceConstants.AT[i], 0);
en[i] = prefs.getInt(PreferenceConstants.EN[i], 0);
}
String name[] = {getString(R.string.a001)};
int prado_got = 0;
if (mgot[0]) {
prado_got += 1;
}
if (mgot[3]) {
prado_got += 1;
}
String prado = String.valueOf(prado_got) + " / 2";
String number[] = {prado};
// Add item to adapter
Area a001 = new Area(name[0], number[0]);
adapter.add(a001);
this.setContentView(fl);
}
}
Thank you in advance.

You can do something like that:
•First insert in your adapter this method
#Override
public Area getItem(int position) {
return [yourArrayAreas].get(position);
}
•Then, in your Activity...
final AreasAdapter adapter = new AreasAdapter(this, arrayOfAreas);
ListView lv = new ListView(this);
lv.setAdapter(adapter);
mListStopsMuni.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id{
Area yourClickArea = adapter.getItem(position);
//Rest of code...
}
});
Good luck ;)

Something like this:
ArrayList<Area> arrayListAreas;
public AreasAdapter(Context context, ArrayList<Area> Areas) {
super(context, 0, Areas);
this.arrayListAreas = Areas;
}
//And then....
#Override
public Area getItem(int position) {
return arrayListAreas.get(position);
}

sort data in ListView alphabetical order

I think best practice would be sorting the list before the calling adaptor.notifyDataChanged() method. Good thing is you do not have to do it manually, just use comparator for sorting.
You can see a comparator example in this link

Instead of using an array as datasource for the list, first use a List. At least, this class extends Collection.
You can define a comparator (e.g define compareTo() on your custom type) and sort your collection before you show it:
Collections.sort(<your_list>);
EDIT: For general collection ordering, see Guava

It seems that you are bundling an int, but unbundling a string.
Try this line:
int position = getIntent().getInt("position");

If I was you I would try to see what type of data I receive. Theoretically you should get an int but the safe way is to get the Bundle that is inside by calling getIntent().getExtras() and then next you try to see if by calling getInt("position") or get("position") you receive what you want.
If the Bundle is null then it is clear you have nothing.
