AlertDialogs are useful for displaying a message to a user and optionally giving them a chance to respond to it. This is just like the setPositiveButton method which acts a "NO" negative button, we will write the logic in OnClickListener anonymous class. Now whenever you create a dialog you can just pass in the custom theme. SetNegativeButton(int textId, DialogInterface.OnClickListener listener) : This is Yes button, when clicked the code written in the OnClickListener onClick() method will be displayed. ![]() SetPositiveButton(int textId, DialogInterface.OnClickListener listener) : one of setPositiveButton (), setNegativeButton () or setNeutralButton (). There are three functions for adding Buttons to Android Dialog, To create an Android AlertDialog with just a single button we can make use of any one method that is provide i.e. It is also possible to display only text message using setMessage() method. You can create a dialog with one, two or even three buttons. Android calls the rest of the methods onCreateDialog and onPrepareDialog.AlertDialog is a subclass of Dialog from android.app package. Your job is to call the method showDialog with the unique integer that identifies your dialog. Android AlertDialog is a subclass of Dialog class. If you donot define onPrepareDialog method, your dialogâs selection state remains unchanged(such as items checked in the checkbox or radio button remains checked even when the dialog is opened for the second time). If you want to do change any properties of your dialog each time it is opened, you can make use of an optional callback onPrepareDialog(int,dialog), which is called every time your dialog is opened whereas onCreateDialog(int) is only called for the very first time your dialog is opened. You should instantiate your dialog inside onCreateDialog method. When the dialog is requested for the first time, Android calls onCreateDialog(int) from your Activity. When you want to show a dialog, call showDialog(int) method and pass in an integer variable that uniquely identifies your dialog. Unlike the previous post, here in this tutorial we would be using few methods of the Activity If you are not familiar with creating an AlertDialog, please refer to the post Create an AlertDialog. ![]()
