Android Simple ListView with Search Functionality Example

First of all create a new project with package name thecrazyprogrammer.androidexample. Now add following code in respective files.

activity_main.xml

<LinearLayout 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" tools:context=".MainActivity"
    android:orientation="vertical"
    android:layout_marginLeft="15dp"
    android:layout_marginRight="15dp"
    android:layout_marginTop="15dp"
    android:layout_marginBottom="15dp">

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/textBox"/>

    <ListView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/list"/>

</LinearLayout>

list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent">
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/text"
        android:textSize="20dp"/>
</LinearLayout>

MainActivity.java

package thecrazyprogrammer.androidexample;

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;
import android.widget.TextView;

public class MainActivity extends Activity {
    EditText textBox;
    TextView text;
    ListView list;
    String country[]={"India","USA","China","Australia","Japan","England","Nepal","Canada","Sri-Lanka","Russia"};
    ArrayAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        textBox=(EditText)findViewById(R.id.textBox);
        text=(TextView)findViewById(R.id.text);
        list=(ListView)findViewById(R.id.list);

        adapter=new ArrayAdapter(this,R.layout.list_item,R.id.text,country);
        list.setAdapter(adapter);


        textBox.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
                adapter.getFilter().filter(s);
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

            }

            @Override
            public void afterTextChanged(Editable s) {

            }
        });
    }
}
