A dialog fragment can wrap a standard dialog such as the alert dialog, but it can also be used to present a custom dialog that gets its appearance from an XML layout file. The code looks almost exactly like a conventional fragment: you inflate the XML file in the onCreateView() method, set the state of its child view objects, and then return it. This gives you complete control over the dialog's appearance and behavior.
- [Narrator] I've previously shown how to use…a dialog fragment to wrap a standard dialog,…such as the alert dialog.…But you can also use a dialog fragment…to present a custom dialog that gets its appearance…from an XML layout file.…In this project, custom dialog,…I've included a layout file named dataentrydialog.xml.…It has three edit text components,…that ask the user to enter some data.…And a couple of buttons labeled Cancel and Save.…
The buttons use a style called borderless button style…that make the applications dialogs look like…material design dialogs.…And they have text values of Cancel and Save.…Now my goal is to present this layout in a dialog…instead of in an activity.…I'll go to my base package,…and I'll create a new java class,…and I'll name it DataEntryDialog.…This class's superclass will be DialogFragment.…
Now, instead of overriding OnCreateDialog,…like I did before, I'll override OnCreateView.…The code is now just like you're working…in a standard fragment.…You'll inflate a layout file,…and then return the resulting view…
