How to add a search to List View

Initially design a xml file as show below:

<?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"

    >

    <EditText android:id="@+id/EtBrandName" android:layout_height="wrap_content" 

    android:layout_width="fill_parent" android:hint="Search">

    </EditText>

    <ListView android:id="@+id/lvItems"

android:layout_width="fill_parent"

android:layout_height="wrap_content" >

</ListView>

</LinearLayout>

Then write the following code in your activity:-

import java.util.ArrayList;

import android.app.Activity;

import android.os.Bundle;

import android.text.Editable;

import android.text.TextWatcher;

import android.widget.ArrayAdapter;

import android.widget.EditText;

import android.widget.ListView;

public class LSearch extends Activity {

private ListView lv1;

private EditText ed;

private String lv_arr[]={"Android","Cupcake","Donut","Eclairs","AndroidPeople","Froyo","Apple","Samsung","Storeage","Sony"};

private ArrayList<String> arr_sort= new ArrayList<String>();

int textlength=0;

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        lv1=(ListView)findViewById(R.id.ListView01);

        ed=(EditText)findViewById(R.id.EditText01);

        // By using setAdpater method in listview we an add string array in list.

        lv1.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , lv_arr));

        ed.addTextChangedListener(new TextWatcher() {

        public void afterTextChanged(Editable s) {

        }

        public void beforeTextChanged(CharSequence s, int start, int count,

        int after) {

        }

        public void onTextChanged(CharSequence s, int start, int before,

        int count) {

        textlength=ed.getText().length();

        arr_sort.clear();

        for(int i=0;i<lv_arr.length;i++)

        {

        if(textlength<=lv_arr[i].length())

        {

        if(ed.getText().toString().equalsIgnoreCase((String) lv_arr[i].subSequence(0, textlength)))

        {

        arr_sort.add(lv_arr[i]);

        }

        }

        }

        lv1.setAdapter(new ArrayAdapter<String>(LSearch.this,android.R.layout.simple_list_item_1 , arr_sort));

        }

        });

    }

}

your output will look as shown below:
