how to implement this code by adding button click that send row data to another activity

Question

I want to implement this code by adding button click that send row data to another activity. Here needed implementation in Spinner and CheckBox, so I pass that value only who is checked and I want to pass quantity also.

Here is my list.java file that have a data that come from web-services.

package com.example.hello;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;

public class List extends ActionBarActivity implements OnClickListener  {

    public void onCreate(Bundle cv) {
        super.onCreate(cv);

        /*Button b22=(Button)findViewById(R.id.b52);
        Button b11=(Button)findViewById(R.id.b51);
        b11.setOnClickListener(this);
        b22.setOnClickListener(this);*/
        String response = null;
        try {
                response = CustomHttpClient.executeHttpGet("http://legacysofttech.com/menulist.php/");

                JSONArray jArray = new JSONArray(response);
                modelItems = new Model[jArray.length()];
                for (int i = 0; i < jArray.length(); i++)
             {
                     JSONObject json_data = jArray.getJSONObject(i);
                     modelItems[i] = new Model(json_data.getString("Item"),json_data.getString("price"), 0,1);
                    // item_list.add(json_data.getString("Item"));
                     //price_list.add(json_data.getString("price")); 
             }

                CustomAdapter adapter = new CustomAdapter(this, modelItems);    
                listview.setAdapter(adapter);                   


            } catch (Exception e) {
                Toast.makeText(getApplicationContext(), "your internet working to slow", Toast.LENGTH_SHORT).show();
                }
    }

    public void onClick(View v)
    {
        switch(v.getId())
        {

        case R.id.b52:

    @Override

There are couple of ways you can achieve this, based on your programming style you can choose!

1-

A very robust way is to use content providers and try to pass URIs between different intents by using Intent.putData(URI) and retrieve it by Intent.getData(). with the URI use an implemented content provider to load the data on the other activity. This method needs some re-coding but is more reliable

2-

Let your Model class implement Parcelable Interface and then pass data with Intent.putExtra("tag", Parcelable) and retrieve on the other intent with Intent.getExtra("tag") .

3-

Just simply pass the integer or string data with Intent.putExtra("quantity", quantity), Intent.putExtra("price", price) and retrieve it in the other application with Intent.getExtra("price") and Intent.getExtra("quantity"). This is simpler but also less flexible. I implement this method for better understanding for you:

//I suppose a variable called "index" is used to hold the index of data you want to send from your Model[] array

Intent intent = new Intent(this, NewActivity.class);
intent.putExtra("quantity", modelItems[index].getPrice());
intent.putExtra("price", modelItems[index].getQuantity());
startActivity(intent);
