Setup Eclipse with Android ADT Plugin for test/code environment (by using Android API Level 7 and Emulator).
P.S- Above page is having around 14 images, download size could be around 700KB.

This Page and/or example code is using Android API Level 7 and tested using corresponding Emulator only.
For latest information please refer Android Official website.

Using Android API Level : 7
In this tutorial we shall be covering Android's ListView API with the help
of an example with some other view elements such as ImageView, CheckBox etc.

Final screen of this Expandable listview example would look like the below image:

List of groups as initial view of this application showing two different
sections as different categories.


Following image shows screen after clicking both the items from the expandable 
ListView:


This example ListView initial screen layout as follows:
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <ListView android:id="@android:id/list" 
            android:layout_width="fill_parent" 
            android:layout_height="fill_parent"/>
</LinearLayout>
listitemview1.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
  <ImageView android:id="@+id/camera1" android:src="@drawable/camera1" 
             android:layout_width="wrap_content" 
                         android:layout_height="wrap_content" />
  <CheckBox android:id="@+id/chkbox1" 
            android:text="Add to Shopping Cart" 
                        android:layout_width="wrap_content" 
                        android:layout_height="wrap_content" />
</LinearLayout>
listitemview2.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
  <ImageView android:id="@+id/cupboard" 
             android:src="@drawable/cupboards1" 
             android:layout_width="wrap_content" 
             android:layout_height="wrap_content" />
  <CheckBox android:id="@+id/chkbox1" 
            android:text="Add to Shopping Cart" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" />
</LinearLayout>
Using Android API such as ListActivity and BaseAdapter class 
files, those can be extended by example specific Java class files such as 
"ExampleListView" extends ExpandableListActivity and a private inner class file
such as "ExampleListViewAdapter" extends BaseExpandableListAdapter class file.
ExampleListView.java
package com.techienjoy.example.listview;

import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.LinearLayout;

public class ExampleListView extends ListActivity {
        
        private LayoutInflater layoutInflater = null;
        private LinearLayout linearLayout = null;                 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        linearLayout = new LinearLayout(this);
        ExampleListViewAdapter adapter = new ExampleListViewAdapter(this);
        setListAdapter(adapter);
    }
    private class ExampleListViewAdapter extends BaseAdapter {
        private Context context;
        public ExampleListViewAdapter(Context context) {
                super();
                this.context = context;
        }

        public int getCount() {
                return 2;
        }

        public Object getItem(int arg0) {
                return null;
        }

        public long getItemId(int arg0) {

                return 0;
        }

        public View getView(int position, View convertView, ViewGroup parent) {
    
           if(layoutInflater == null)
                layoutInflater = (LayoutInflater) context.
		                    getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    

           if(position == 0) {
             linearLayout = (LinearLayout) layoutInflater.
	                            inflate(R.layout.listitemview1, null);
           }
           if(position == 1) {
             linearLayout = (LinearLayout) layoutInflater.
	                            inflate(R.layout.listitemview2, null);
           }
           return linearLayout;

        }
    }
}
Once all these files are placed in folders as appropriate within Eclipse 
Workspace and Android Project, Java files compiled and *.apk file created. 
Then this APK file can be published to Android Emulator for getting installed
 and displaying on invocation of this application at runtime.
