Android Alert Dialog Example
Author : Ishtek

Setup Eclipse with Android ADT Plugin for test/code environment (by using Android API Level 7 and Emulator).
P.S- Above page is having around 14 images, download size could be around 700KB.

This Page and/or example code is using Android API Level 7 and tested using corresponding Emulator only.
For latest information please refer Android Official website.

Using Android API Level : 7 In this example we shall see a very simple ways to work with AlertDialog API from Android platform and I have used AlertDialog API from Android Platform.
Main Activity ScreenOn Button click Screen showing AlertDialog
Layout and widgets used in these activities are provided by coding only. Code for these activities are as shown below: TestAlertDialog.java
/** * This code is provided on "AS IS" basis without guarantee/warranty * of any kind. Use of this code subjected to user's own risk. * @Author: Ishtek */ package com.techienjoy.example; import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.content.DialogInterface.OnCancelListener; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.LinearLayout; public class TestAlertDialog extends Activity { private LinearLayout linearLayout; private AlertDialog.Builder alertBuilder; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); linearLayout = new LinearLayout(this); linearLayout.setLayoutParams(new LinearLayout.LayoutParams(400,400)); Button button = new Button(this); button.setText("Alert Me"); addContentView(button, new LinearLayout.LayoutParams(50,50)); alertBuilder = new AlertDialog.Builder(this); alertBuilder.setTitle("Sample Title"); alertBuilder.setMessage("Sample Message"); alertBuilder.setPositiveButton("Button1", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }); alertBuilder.setNegativeButton("Button2", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }); alertBuilder.setOnCancelListener(new OnCancelListener() { @Override public void onCancel(DialogInterface dialog) { } }); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { alertBuilder.show(); } }); } }
Just incase: Following exception I received and solved it how, as follows: 03-01 19:56:42.272: ERROR/AndroidRuntime(27056): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application I resolved this error by using "this" instead of getApplicationContext(), in the following line of code: "alertBuilder = new AlertDialog.Builder(this);" Hope this helps. Another example using customized dialog box with a layout:

How to make Alert Dialog as non-modal in this very example?
I mean AlertDialog should be visible, and should not interfere user's interaction with 
other components on screen!!!

Can you please elaborate your query a bit more ...
Is it that you try to show a AlertDialog, still allowing clicking of the button once more, thus showing this dialog again???

But to my understanding what purpose it is going to solve... with multiple dialogs shown on screen.

Just curious enough..
