How to SetOnClick for Item in List View but without going to another activity

Question

First of All Sorry for this Question title if it is not suitable for my case but am gonna explain my Case, First I created a fragment and created in this fragment a list View,and created another xml file which have the view for every item in list, created a java class for a setter and getter for this item.xml and created also an adapter class which have the view like this in this view there a small Relative layout with orange color which have the quantity and on the right of this small orange box I have a button which the function of this button should reduces the quantity of Item in list.So all I need if I Click on Item In List View it gonna be increase the quantity in this small box like for example if I click the pineapple item it will increse the number of item I clicked and replace instead of 0 will be 1 and id I Clicked another time on the same item it will replace instead of 1 by 2 and so on, for the small greay button it reduces the quantity in the small orange box this is the list View Fragment.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="abtech.waiteriano.com.waitrer.fragments.MenuLVFragment">

    <ListView
        android:id="@+id/menuLV"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</FrameLayout>

this is Fragment.Java

    @Override

        menuListView = (ListView) rootView.findViewById(R.id.menuLV);
        customMenuListViewAdapter = new CustomMenuListViewAdapter(getActivity(), R.layout.menu_row_list, listMenuArray);
        menuListView.setAdapter(customMenuListViewAdapter);
        listMenuArray.clear();
        String menuListSTR = "";
        if (MenuActivity.Prst_ID.trim() == "-1")
            menuListSTR = "Select ID,Code,Name,Name2 From Presets Where Active = 1 And Rest_ID_Active = 1 AND OutLet_ID_Active = 1 ORDER BY Code";

        ResultSet rs = ConnectionClass.Ret_RS(menuListSTR);
        try {
            while (rs.next()) {
                listMenuArray.add(new MenuListItem(rs.getString("Name")));

        menuListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

                Toast.makeText(getActivity(),"You Clicked Here",Toast.LENGTH_SHORT).show();
            }
        });
        return rootView;


    }
}

this is item.xml

and this is getter and setter class package abtech.waiteriano.com.waitrer.getters_and_setters;

import android.graphics.Bitmap;

/**
 * Created by dell on 3/1/2017.
 */

public class MenuListItem {
    Bitmap image;
    String menuItemName;
    String minusButton;
    String plusButton;
    String qtyView;

    public MenuListItem(String menuItemName) {
        super();
        this.image = image;
        this.menuItemName = menuItemName;
        this.minusButton = minusButton;
        this.plusButton = plusButton;
        this.qtyView = qtyView;
    }

    public Bitmap getImage() {
        return image;
    }

    public void setImage(Bitmap image) {
        this.image = image;
    }

    public String getMenuItemName() {
        return menuItemName;
    }

    public void setMenuItemName(String menuItemName) {
        this.menuItemName = menuItemName;
    }
    public String getMinusButton() {
        return minusButton;
    }

    public void setMinusButton(String minusButton) {
        this.minusButton = minusButton;
    }
    public String getPlusButton() {
        return plusButton;
    }

    public void setPlusButton(String plusButton) {
        this.plusButton = plusButton;
    }
    public String getQtyView() {
        return qtyView;
    }

    public void setQtyView(String qtyView) {
        this.qtyView = qtyView;
    }
}

and this is my Adapter Class

        super(context,layoutResourceId,dataListMenu);
        this.layoutResourceId = layoutResourceId;

        this.dataListMenu = dataListMenu;


    }

    @NonNull

        View listMenuRow = convertView;
        RecordListMenuHolder recordListMenuHolder = null;

        if(listMenuRow == null){
            LayoutInflater inflater = ((Activity) context).getLayoutInflater();
            listMenuRow = inflater.inflate(layoutResourceId, parent, false);

            recordListMenuHolder = new RecordListMenuHolder();

            recordListMenuHolder.qtyView = (RelativeLayout) listMenuRow.findViewById(R.id.qtyID);
            recordListMenuHolder.minusBtn = (Button) listMenuRow.findViewById(R.id.minusBtn);
            listMenuRow.setTag(recordListMenuHolder);
        }else{
            recordListMenuHolder = (RecordListMenuHolder)listMenuRow.getTag();
        }

        MenuListItem menuListItem = dataListMenu.get(position);
        recordListMenuHolder.listMenuTV.setText(menuListItem.getMenuItemName());

        return listMenuRow;
    }

    static class RecordListMenuHolder {
//        Image menuItemImage;
        TextView listMenuTV;
        RelativeLayout qtyView;
        Button minusBtn;
        Button plusBtn;
    }
}

sorry If My explanation is not understandable,if there any enquiry for codes please leave a comment

Answer 1

public class CustomMenuListViewAdapter extends ArrayAdapter<MenuListItem> {
    Context context;
    int layoutResourceId;
    ArrayList<MenuListItem> dataListMenu = new ArrayList<MenuListItem>();
        RecordListMenuHolder recordListMenuHolder;
