Fill all the details and name your activity as MainActivity. 2. Once the project is created open your activity_main.xml file and Add Below Code.

<?xml version="1.0" encoding="utf-8"?>  
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
   xmlns:app="http://schemas.android.com/apk/res-auto"  
   xmlns:tools="http://schemas.android.com/tools"  
   android:layout_width="match_parent"  
   android:layout_height="match_parent"  
   android:orientation="vertical"  
   tools:context="com.targetandroid.info.alertdialog.MainActivity">  
   <Button  
     android:layout_width="match_parent"  
     android:layout_height="wrap_content"

     android:id="@+id/btexit_aleart"  
     android:background="@android:color/holo_green_dark"/>  
 </LinearLayout>

3. Now Open Your MainActivity.java Add Below Code In File

package com.targetandroid.info.alertdialog;  
 import android.app.AlertDialog;  
 import android.content.DialogInterface;  
 import android.support.v7.app.AppCompatActivity;  
 import android.os.Bundle;  
 import android.view.View;  
 import android.widget.Button;  
 import android.widget.ImageButton;  
 import android.widget.Toast;  

 public class MainActivity extends AppCompatActivity { 
 
   //creating variabels  
   private Button btexit_aleart,btradio_aleart;  
   private ImageButton btcheck_aleart;  
   private int selected; 
 
   @Override  
   protected void onCreate(Bundle savedInstanceState) {  
     super.onCreate(savedInstanceState);  
     setContentView(R.layout.activity_main);  
     //Initializing views  
     btexit_aleart=(Button)findViewById(R.id.btexit_aleart);  
     btradio_aleart=(Button)findViewById(R.id.btradio_aleart);  
     btcheck_aleart=(ImageButton)findViewById(R.id.btcheck_aleart);  


     btexit_aleart.setOnClickListener(new View.OnClickListener() {  
       @Override  
       public void onClick(View v) {  
         showExitAlertDialogue();  
       }  
     });  


     btradio_aleart.setOnClickListener(new View.OnClickListener() {  
       @Override  
       public void onClick(View v) {  
         final String[] select={"Maharashtra","Kolkata","Rajasthan","Delhi","M.p"};  
         AlertDialog dialog=new AlertDialog.Builder(MainActivity.this)  
             .setTitle("Select State")  
             .setSingleChoiceItems(select, 1, new DialogInterface.OnClickListener() {  
               @Override  
               public void onClick(DialogInterface dialog, int which) {  
                 selected = which;  
               }  
             })  
             .setPositiveButton("Ok", new DialogInterface.OnClickListener() {  
               @Override  
               public void onClick(DialogInterface dialog, int which) {  
                 Toast.makeText(MainActivity.this, "Your State is " + select[selected], Toast.LENGTH_SHORT).show();  
               }

             .create();  
         dialog.show();  
       }  
     });  


     btcheck_aleart.setOnClickListener(new View.OnClickListener() {  
       @Override  
       public void onClick(View v) {  
         final String[] check={"Cricket","Hockey","Football","Badminton","Volleyball","Baseball"};  
         AlertDialog dialog=new AlertDialog.Builder(MainActivity.this)

               public void onClick(DialogInterface dialog, int which, boolean isChecked) {  
                 int checked=which;  
                 if(isChecked){  
                   Toast.makeText(MainActivity.this,"You Selected "+check[checked],Toast.LENGTH_SHORT ).show();  
                 }  
                 else{  
                   Toast.makeText(MainActivity.this,"You UnSelected "+check[checked],Toast.LENGTH_SHORT ).show();  
                 }  
               }  
             })  
             .setPositiveButton("Ok", new DialogInterface.OnClickListener() {  
               @Override  
               public void onClick(DialogInterface dialog, int which) {  
               }  
             })  
             .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {  
               @Override  
               public void onClick(DialogInterface dialog, int which) {  
               }
