Android ListView with Horizontal CheckBox.Part-2

Part-2
In previous blog i shown Listview with RadioGroup and RadioButton.
Now i am going to show how to make a list of Horizontal CheckBox.

Screenshot.1) Before selecting any Checkbox

Screenshots.2) After Checked the list of Checkbox

In Previous blog i used RadioGroup to achieve the ListView with horizontal RadioButton.
But for Checkbox i am going to use LinearLayout and inflate the view in Adapter class.

Steps:-

1) res/layout/activity_main.xml

RelativeLayout 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=".MainActivity" >
    <ListView
        android:id="@+id/list"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:cacheColorHint="#00000000"
        android:divider="#b5b5b5"
        android:dividerHeight="1dp" />
</RelativeLayout>

2) res/layout/horizontal_checbox.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/headingitem"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="left"
        android:padding="5dp" />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/linearmain"
        android:layout_gravity="center_horizontal|center_vertical"
        android:orientation="horizontal" >
    </LinearLayout>

</LinearLayout>

3) src/ListAdapter.java

package com.list.checkbox;

import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;
import android.widget.TextView;

public class ListAdapter extends ArrayAdapter<Option> {

    Context context;
    int layoutResourceId;
    Option data[] = null;

    public ListAdapter(Context context, int layoutResourceId,
            Option[] data) {
        super(context, layoutResourceId, data);
        this.layoutResourceId = layoutResourceId;
        this.context = context;
        this.data = data;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View row = convertView;
        MatrixHolder holder = null;

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

            holder = new MatrixHolder();
            holder.txtTitle = (TextView) row.findViewById(R.id.headingitem);
            holder.position = position;
            holder.layout = (LinearLayout) row.findViewById(R.id.linearmain);
            final CheckBox[] checkbox = new CheckBox[5];
           
            for (int i = 0; i < 5; i++) {
                checkbox[i] = new CheckBox(context);
                LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                        0, LayoutParams.WRAP_CONTENT);
                params.weight = 1f;
                params.setMargins(10, 0, 10, 10);
                holder.layout.addView(checkbox[i], params);
            }

            row.setTag(holder);
        } else {
            holder = (MatrixHolder) row.getTag();
        }

        Option option = data[position];
        holder.txtTitle.setText(option.title);
        return row;
    }

    static class MatrixHolder {
        TextView txtTitle;
        LinearLayout layout;
        int position;
    }
}

4) finally Your MainActivity.java

package com.list.checkbox;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.ListView;

public class MainActivity extends Activity {
    private ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
         Option weather_data[] = new Option[]
                    {
                        new Option("Heading1"),
                        new Option("Heading2"),
                        new Option("Heading3"),
                        new Option("Heading4"),
                        new Option("Heading5")
                    };
            ListAdapter adapter = new ListAdapter(this,
                            R.layout.horizontal_checbox, weather_data);
                    listView = (ListView)findViewById(R.id.list);
                    listView.setAdapter(adapter);
        }

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            getMenuInflater().inflate(R.menu.activity_main, menu);
            return true;
        }


       
    }
