About the title
Ah, this damned title, and everyone cheated in, think is tall, in fact, just a small package, big guys don’t spray.
EverythingDialogFragment
With the increase of business, a variety of dialog styles need to be realized. Traditionally, a variety of dialogs need to be written. On the one hand, it is difficult to maintain, and on the other hand, in multi-person development, everyone will write different dialogs, resulting in poor code reuse. Self-defined DialogFragment is a base class, by personal experience and ability, there are still deficiencies in the code, but also please big men more advice.
About the name
I originally wanted to choose a Basic edialogfragment, but the name was too common, so I had to choose a fancy name, but not too high profile, but not lose the connotation. Then I Google translated a lot of words, and finally found Everything, ha ha, everyone, don’t insult me.
