"Reading notes-the zero-start of Android game programming" 7.Android game development Common system controls (Dialog)

In Android app Development, Dialog (dialog box) is created simple and easy to manage and is often used, and dialog box default style is similar to creating style activity.
The class of builder under Android.app.AlertDialog is introduced first. Builder is a subclass of the Alertdialog class, and it is also its inner class. As the name implies, builder is the equivalent of a concrete constructor, which sets the dialog property through builder and then displays the Builder (dialog box).

I made a dialog display effect set of small demo, the effect is as follows (GIF picture is larger, need point load time):
