There are four type of alert boxes are available. Here I describe how to create simple alert box.

package com.alt; // package name

import android.app.Activity;

import android.app.AlertDialog;

import android.content.DialogInterface;

import android.os.Bundle;

import android.widget.Toast;

public class alertBox extends Activity {

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

AlertDialog.Builder altDialog= new AlertDialog.Builder(this);

altDialog.setMessage("Alert Dialog Message"); // here add your message

altDialog.setNeutralButton("OK", new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

// TODO Auto-generated method stub

Toast.makeText(getApplicationContext(), "Ok button Clicked ", Toast.LENGTH_LONG).show();

}

});
