Dialog Box example in android

Question

I want to display a dialog box on a button click. Here is my code, but it is not working.

AlertDialog.Builder builder = new AlertDialog.Builder(
                        getApplicationContext());
                builder.setCancelable(true);
                builder.setTitle("Title");
                builder.setInverseBackgroundForced(true);
                builder.setPositiveButton("Yes",
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog,
                                    int which) {
                                dialog.dismiss();
                            }
                        });
                builder.setNegativeButton("No",
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog,
                                    int which) {
                                dialog.dismiss();
                            }
                        });
                AlertDialog alert = builder.create();
                alert.show();

What is the problem/error-message? "Not working" is not a problem-description ;) — dst, May 16 '11 at 07:45
Where this code is placed? In onCreate()? Then it is wrong. Dialog showing should be called when activity has been shown, so put this code in some button onClickListener. — Vladimir Ivanov, May 16 '11 at 07:55
if you are using alert dialog then it is not need to dismiss for alert dialog. when you will click on button of alert dialog it will be automatically dismiss.. — Niranj Patel, May 16 '11 at 07:59
Problem solved. I placed the code in onCreate() method. I corrected it and placed it in a button onClick() method, its working perfectly. Thanks Mr. Vladimir Ivanov. — Krishna, May 16 '11 at 11:29

try this,

instead of passing getApplicationContext() pass this;

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

This is a very old post however I have made a class that I think it can help to keep the code clean

https://github.com/houmanka/DialogMaker

You dont need to worry about the OnClickListener all have been taking care of. Just override the methods and you are done. Also I put the support for Standard and Neutral too.

Cheers

Hope it helps someone. H.
