import android.widget.TextView;

public class listadapterfdgdfg extends ArrayAdapter<String> {
    customButtonListener customListner;

    public interface customButtonListener {
        public void onButtonClickListner(int position,String value);
    }

    public void setCustomButtonListner(customButtonListener listener)
    {
        this.customListner = listener;
    }

    private Context context;

    private ArrayList<String> data = new ArrayList<String>();
    private ArrayList<String> Price = new ArrayList<String>();

    public listadapterfdgdfg(Context context, ArrayList<String> dataItem,ArrayList<String> price) {
        super(context, R.layout.child_row,dataItem);
        this.data = dataItem;
        this.Price=price;
        this.context = context;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder;
        ViewHolder viewHolder2;

            viewHolder.prices =(TextView)convertView.findViewById(R.id.pricemine);

            //viewHolder2.prices= (TextView)convertView.findViewById(R.id.pricemine);
            viewHolder.button = (Button) convertView.findViewById(R.id.childButton);
            convertView.setTag(viewHolder);
        } else {

            viewHolder2 = (ViewHolder) convertView.getTag();
        }
        final String temp = getItem(position);

        viewHolder.text.setText(temp);

        final String temp1 =getItem(position);

        viewHolder.prices.setText(temp1);

        viewHolder.button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                if (customListner != null) {
                    customListner.onButtonClickListner(position,temp);
                }
            }
        });

        return convertView;
    }

    public class ViewHolder {
        TextView text;
        TextView prices;
        Button button;
    }
}

here I call this class in that way

I add textview of price in xml also add price array list in constructor of listadapter it shows data of dataitems in screeen it shows same item name as price i know the problem but dont know how to tackle this the problem is here

public listadapterfdgdfg(Context context, ArrayList<String>   dataItem,ArrayList<String> price) {
        super(context, R.layout.child_row,dataItem);
        this.data = dataItem;
        this.Price=price;
        this.context = context;
    }

It show price as if i declare price data it show itmename as if I declare itemlis data

wan to add price of items

Answer 1

here is a full answer of what i told you:

1- the model class for data

public class MyData{
    private String name = "";
    private double price = 0;

    //Setters and Getters...
}

2- the adapter class, rename to MyDataListAdapter

public class MyDataListAdapter extends ArrayAdapter<MyData> {
    private ArrayList<MyData> data = null;

    public MyDataListAdapter(Context context, ArrayList<MyData> dataList) {
        super(context, R.layout.child_row,dataList);
        this.data = dataList;
        this.context = context;
    }//constructor


    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder;
        if (convertView == null) {
            LayoutInflater inflater = LayoutInflater.from(context);
            convertView = inflater.inflate(R.layout.child_row, null);
            viewHolder = new ViewHolder();
            viewHolder.text = (TextView) convertView.findViewById(R.id.childTextView);
            viewHolder.prices =(TextView)convertView.findViewById(R.id.pricemine);
            viewHolder.button = (Button) convertView.findViewById(R.id.childButton);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        //you can use data.get(position) too
        final MyData myDataItem = getItem(position);

        viewHolder.text.setText(myDataItem.getName());
        viewHolder.prices.setText(myDataItem.getPrice());
        viewHolder.button.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (customListner != null) {
                    //pass name or price, or pass myDataItem object and handle it at onButtonClickListner()
                    customListner.onButtonClickListner(position,myDataItem.getName());
                }

            }
        });

        return convertView;
    }

    public class ViewHolder {
        TextView text;
        TextView prices;
        Button button;
    }
}//MyDataListAdapter

now from activity or any place, instantiate adapter

ArrayList<MyData> alldata = new ArrayList();
alldata.add(dataItem1); //.. add all items needed
MyDataListAdapter adapter = new MyDataListAdapter (context, alldata);
mListView.setAdapter(adapter);
