AlertDialog with List

Here i'm giving example how to display list of items in AlertDialog.

ScreenShots:

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" >

    <Button

        android:id="@+id/button_alertDialogList"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentTop="true"

        android:layout_centerHorizontal="true"

        android:layout_marginTop="98dp"

        android:text="Dialog List" />

</RelativeLayout>

strings.xml:

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

<resources>

    <string name="app_name">AlertDialog with List</string>

    <string name="action_settings">Settings</string>

    <string name="hello_world">Hello world!</string>

    <string name="names">Mobile Platforms</string>

    <string-array name="mobileplatforms">

        <item >Android</item>

        <item >iPhone</item>

        <item >BlackBerry</item>

    </string-array>

    

</resources>

MainActivity.java:

package com.ram.alertdialogwithlist;

import android.app.Activity;

import android.app.AlertDialog;

import android.content.DialogInterface;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.Toast;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button showDialog = (Button) findViewById(R.id.button_alertDialogList);

showDialog.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View arg0) {

// TODO Auto-generated method stub

final String[] names = getResources().getStringArray(

R.array.mobileplatforms);

AlertDialog.Builder builder = new AlertDialog.Builder(

MainActivity.this);

builder.setTitle(R.string.names);

builder.setItems(R.array.mobileplatforms,

new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface arg0, int index) {

// TODO Auto-generated method stub

switch (index) {

case 0:

Toast.makeText(getApplicationContext(),

names[index] + " Selected",

Toast.LENGTH_LONG).show();

break;

case 1:

Toast.makeText(getApplicationContext(),

names[index] + " Selected",

Toast.LENGTH_LONG).show();

break;

case 2:

Toast.makeText(getApplicationContext(),

names[index] + " Selected",

Toast.LENGTH_LONG).show();

break;

}

}

});

AlertDialog alertList = builder.create();

alertList.show();

}

});

}
