Step 2 : Open res -> layout -> activity_main.xml (or) main.xml and add following code :

<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" >

    <StackView
        android:id="@+id/stackView1"
        android:animateLayoutChanges="true"
        android:layout_width="fill_parent"
     android:layout_height="fill_parent" >
      
    </StackView>

</RelativeLayout>

Step 3 : Open res -> layout -> item.xml and add following code :

<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" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="35dp"
        android:text="TextView" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="61dp"
        android:src="@drawable/ic_launcher" />

</RelativeLayout>

Step 4 : Open src -> package -> MainActivity.java and add following code :

package com.gudivada.hemanthsomaraju;

import java.util.ArrayList;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.StackView;

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
     
        StackView stk = (StackView)this.findViewById(R.id.stackView1);
     
        ArrayList<StackItem> items = new ArrayList<StackItem>();
        items.add(new StackItem("text1", this.getResources().getDrawable(R.drawable.ic_launcher)));
        items.add(new StackItem("text2", this.getResources().getDrawable(R.drawable.ic_launcher)));
        items.add(new StackItem("text3", this.getResources().getDrawable(R.drawable.ic_launcher)));
        items.add(new StackItem("text4", this.getResources().getDrawable(R.drawable.ic_launcher)));
        items.add(new StackItem("text5", this.getResources().getDrawable(R.drawable.ic_launcher)));
     
        StackAdapter adapt = new StackAdapter(this, R.layout.item, items);
     
        stk.setAdapter(adapt);
    }

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


Step 5 : Open src -> package -> StackItem.java and add following code :

package com.gudivada.hemanthsomaraju;

import android.graphics.drawable.Drawable;

public class StackItem {

public String text;
public Drawable img;

public StackItem(String text,Drawable photo)
{
this.img = photo;
this.text = text;
}
}

Step 6 : Open src -> package -> StackAdapter.java and add following code :

package com.gudivada.hemanthsomaraju;

import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class StackAdapter extends ArrayAdapter<StackItem> {

private ArrayList<StackItem> items;
private Context ctx;

public StackAdapter(Context context, int textViewResourceId,
ArrayList<StackItem> objects) {
super(context, textViewResourceId, objects);

this.items = objects;
this.ctx = context;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)
ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.item, null);
}

StackItem m = items.get(position);

if (m != null) {
TextView text = (TextView) v.findViewById(R.id.textView1);
ImageView img = (ImageView)v.findViewById(R.id.imageView1);

if (text != null) {
text.setText(m.text);
img.setImageDrawable(m.img);
}
}
return v;
}
}

Step 7 : Open AndroidManifest.xml and add following code :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.gudivada.hemanthsomaraju"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.INTERNET"/>
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.gudivada.hemanthsomaraju.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Step 8 : Our output will be like this :
