introduce

Dialogfragment was introduced in Android 3.0. Is a special fragment used to display a modal dialog box on the content of the activity. Typical: display warning box, input box, confirmation box, etc.

Before dialogfragment is generated, we create dialog boxes: alertdialog and dialog are generally used. Note: the official does not recommend directly using dialog to create dialog boxes.
