1. create a activity_main.xml in Android Project.
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"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="search"
android:textStyle="bold"/>
<EditText
android:id="@+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView1"
android:layout_alignRight="@+id/textView1"
android:layout_below="@+id/textView1"
android:ems="10" />
<ListView
android:id="@+id/listView1"

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/editText1"
android:layout_below="@+id/editText1" >
</ListView>
</RelativeLayout>
2.create a another xml for list_row.xml In this xml create a textview for listview
list_row.xml:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dip"
android:textSize="16dip"
android:textStyle="bold" >
</TextView>
3. create a java class called MainActivity.java. Using the addTextChangedListener only search the text using method getFilter().filter(s);
MainActivty.java:
package com.example.list;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Toast;
public class MainActivity extends Activity {
ListView lv;
EditText ed;
ArrayAdapter<String> adapter;
List<String> array;
String[] phone={"Samsung","Nokia","Motorola","iphone","Sony Xperia","Micromax","Karbonn","HTC","LG","Nexus"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv=(ListView)findViewById(R.id.listView1);
ed=(EditText)findViewById(R.id.editText1);
array=new ArrayList<String>(Arrays.asList(phone));
adapter=new ArrayAdapter<String>(this,R.layout.list_row,array );
lv.setAdapter(adapter);
ed.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
MainActivity.this.adapter.getFilter().filter(s);
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
});
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3)
{
Toast.makeText(getApplicationContext(),"your position is " +arg2, 4).show();
}
});
}
}
4.Run the Application and Here the output is shown below.
