First, the simple Alertdialog

Below, create a simple alertdialog and display it:
New Alertdialog.builder (Getapplicationcontext ())
. Settitle ("Confirm")
. SetIcon (R.drawable.ic_launcher)
. Setmessage ("Are you sure you want to end the application?" ")
. Show ();

Second, with the button Alertdialog

The example above is very simple, so let's add a few buttons to this alertdialog,
Prompt for delete Operation dialog box
New Alertdialog.builder (Getapplicationcontext ())
. Settitle ("Confirm")
. SetIcon (R.drawable.ic_launcher)
. Setmessage ("Are you sure you want to end the application?" ")
. Setpositivebutton ("OK", new Dialoginterface.onclicklistener () {
public void OnClick (Dialoginterface dialog, int which) {
Finish ();
}
})
. Setnegativebutton ("Cancel", new Dialoginterface.onclicklistener () {
public void OnClick (Dialoginterface dialog, int which) {
No action is taken when the user taps this button
}
})
. Show ();
