ListView Example in Android

To create a simple listview in android as shown in below image, we generally need three things.

1. ListView

2. ArrayAdapter

3. Simple String array.

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" >

    <ListView

        android:id="@+id/listView1"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_centerHorizontal="true"

        android:layout_centerVertical="true" >

    </ListView>

</RelativeLayout>

MainActivity.java

package com.example.listview;

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.widget.AdapterView;

import android.widget.AdapterView.OnItemClickListener;

import android.widget.ArrayAdapter;

import android.widget.ListView;

import android.widget.Toast;

public class MainActivity extends Activity {

   ListView list;

String books[] = {"Android","Java","Hibernate","JavaScript","AJAX","Jquery","JSP","XML","HTML","PHP"};

   

@Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

    

list = (ListView)findViewById(R.id.listView1);

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,android.R.id.text1, books);

list.setAdapter(adapter);

list.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView<?> arg0, View arg1, int position,

long arg3) {

// TODO Auto-generated method stub

int itemPosition = position; 

String itemvalue = (String)list.getItemAtPosition(position);

Toast.makeText(getApplicationContext(), ""+itemvalue+"@ Position: "+itemPosition,Toast.LENGTH_LONG).show();

}

});

}

}

Output:
