Please Proceed following steps :

STEP 1 : CREATE A PROJECT MultipleListView

STEP 2 : PUT FOLLOWING CODE IN MainActivity 


package com.ritesh.multiplelistview;

import java.util.ArrayList;

import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivity extends Activity implements OnItemClickListener  {
private ArrayAdapter<String> adaptern;
private String[] namelist = new String[] {"android","aman","bharat","banana","calc","come","dell","dhoom","ele",
"fork","fail","goyal","home","imagine","jama","kaman","lawan","mohit","mohan","noida","oman","police","qatar","rest",

"s","t","u","v","w","x","y","z"};
private ListView listmain;
private ArrayList<String> list_name=new ArrayList<String>();

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView listside=(ListView)findViewById(R.id.listviewside);
listmain=(ListView)findViewById(R.id.listViewmain);

 
for (int i = 0; i < namelist.length; i++) {
list_name.add(namelist[i]);

}

ArrayAdapter<String> adapter=new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, name);
listside.setAdapter(adapter);


adaptern=new ArrayAdapter<String>(MainActivity.this, R.layout.itemtext, list_name);
listmain.setAdapter(adaptern);

listside.setOnItemClickListener(this);
}

 @Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
 list_name.clear();
 if ((name[arg2]).equals("#")) {
 for (int i = 0; i < namelist.length; i++) {
list_name.add(namelist[i]);
}
}
 else {
 
 for (int i = 0; i < namelist.length; i++) {
if((namelist[i].substring(0, 1)).equals(name[arg2])){
list_name.add(namelist[i]);
}
   }
  }
    adaptern.notifyDataSetChanged();
}

       }

STEP 3 : PUT THIS CODE IN activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    xmlns:android1="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent" >

    <ListView

        android1:id="@+id/listViewmain"

        android1:layout_width="match_parent"

        android1:layout_height="wrap_content"

        android1:layout_alignParentLeft="true"

        android1:layout_alignParentTop="true"

        android1:layout_toLeftOf="@+id/listviewside" >

    </ListView>

    

    

     <ListView

        android1:id="@+id/listviewside"

        android1:layout_width="40dp"

        android1:layout_height="wrap_content"

        android1:layout_alignParentRight="true"

      

        android1:layout_alignParentTop="true" >

    </ListView>

</RelativeLayout>

     android:gravity="center_vertical"

     android:paddingLeft="20dp"

     android:background="@android:color/black"

    android:textAppearance="?android:attr/textAppearanceMedium" />

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.ritesh.multiplelistview"
