Tag: list

I have 3 classes: Items, AdapterItems, Main Class 2 Layout: Show List, Main Layout.

Code of class objects:

Here I create the objects

package com.example.myapplication;
import android.widget.CheckBox;

public class Items {
private string PriceProduct;

public items (String Productprice) {
this.ProductPrice = ProductPrice;
}

public String getProductPrice () {return ProductValue;}
}

Adapter Items Class Code:

Here I create the adapter

package com.example.myapplication;

import android.content.Context;
android.view.LayoutInflater Import;
android.view.View import;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import java.util.ArrayList;


public class Adapter Items extends BaseAdapter {
private context context;
private ArrayList listItems;

public Adapter Items (context context, ArrayList listItems) {
this.context = context;
this.listItems = listItems;
}

// Count the objects to load
@Override
public int getCount () {
return listItems.size ();
}

// return the list
@Override
public object getItem (int position) {
return listItems.get (position);
}

//
@Override
public long getItemId (int position) {
return 0;
}

// where the list is created and we assign the values ​​of each element
@Override
public view getView (int position, view convertView, ViewGroup parent) {
Items items = (Items) getItem (position);

convertView = LayoutInflater.from (context) .inflate (R.layout.activity_show_listing, null);
TextView txt Show Price = (TextView) convertView.findViewById (R.id.txt Show Price);

img_avatar.setImageResource (items.getAvatar ());
txt_product.setText (items.getProduct ());
txtShowPrice.setText (items.getProductPrice ());
return convertView;
}
}

Main class calling the layout code:

here is the prolema in the layout I have the chekbox but they are not added in the daptador or in the article class, because from the database, the objects filled the objects with data and the chekbox no data needed, so that only the price object receives information with sql

package com.example.myapplication;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
android.media.MediaCodec import;
import android.os.Bundle;
android.view.View import;
import android.widget.CheckBox;
import android.widget.ListView;
import android.widget.TextView;
android.widget.Toast import;

import java.util.ArrayList;

public class OrderProduct extends AppCompatActivity {
private ListView lst_items;
private adapterItems adapter;

@Override
protected void onCreate (bundle savedInstanceState) {
super.onCreate (savedInstanceState);
setContentView (R.layout.activity_order_product);

lst_items = (ListView) findViewById (R.id.lst_items);
adapter = new AdapterItems (this, GetArrayItems ());
lst_items.setAdapter (adapter);
}

private ArrayList GetArrayItems () {
ArrayList listitems = new ArrayList <> ();

// Load database records
AdminSQLiteOpenHelper admin = new AdminSQLiteOpenHelper (this, "administration", null, 1);
SQLiteDatabase DataBase = admin.getWritableDatabase ();

Row cursor = DataBase.rawQuery ("Select price from items", null);
if (row.moveToFirst ()) {
do
// Design of records These are objects and we introduce the data of the tables sql into the object lists
listitems.add (new Items (row.getString (0)));

} while (row.moveToNext ());
}
DataBase.close ();

return list items;
}
}

As you can see, the checkboxes with the price text view are repeated. I would like to add the prices according to the list checkboxes. I can not access the check boxes because they are in a different layout to display the list of the design and code in the main layout I can not call the chekbox.

my goal is to display a list of prices and when choosing chekbox i make the sum of the selected or create the object in item, but the item objects get data from the database or i create a class for the layout to list and from there validate the selected data. I am an apprentice, I need help.
