Dialog, toast, snackBar reminder for Android Development

Today, I will bring you a simple and easy to understand micro skills article. There are no advanced technical points, but the focus is on the details. I believe it can help many friends.

Dialog and toast are certainly familiar to everyone. We usually use too much. SnackBar is a new control provided in the design support library. Some friends may have used it, and some friends may not understand it. But do you really know when to use dialog, toast and snackBar? Look at the renderings first:

1，Dialog

First, let's introduce the usage of dialog:

The display effect will be different when running on different versions of mobile phones, but since it is a trick, Google has fully considered this, and also provides an alertdialog class in the appcompat-v7 Library:

4. Summary

Now you have three ways to prompt users, dialog, toast and snackBar. Let's summarize the use timing of these three ways:

Toast: toast is used when the prompt just tells the user that something has happened and the user does not need to respond to it. SnackBar: in any scenario other than the above two, snackBar may be your best choice.
