Toast is a message box type in the Android system. It is a lightweight message prompt. It often appears in the form of a small pop-up box, usually 1 to 2
Seconds will disappear automatically and can appear anywhere on the screen. Unlike Dialog, it has no focus. Toast
The design idea is not to attract attention as much as possible, but also to display information to users, hoping they can see it.

Test APP download address:

https://github.com/appium/sample-code/raw/master/sample-
code/apps/ApiDemos/bin/ApiDemos-debug.apk

First, download the apk package at the above address to the local and install it into the simulator; Open API Demos in the simulator and click "Views" - "Popup Menu" - "Make" successively
A popup - "search", a message prompt box will pop up, as shown in the figure:

In the above figure, "Clicked Popup menu item Search" is a Toast, but it usually stays on the page for only about 2 seconds through Appium
It is generally not easy for inspectors to obtain this element.

Get Toast

Open the API Demos application in the simulator and click "Views" - "Popup Menu" - "Make a Popup"-"Search" to view the page
Toast element.

Here, the Xpath expression is used to locate Toast because the class of Toast
Attribute is special. The element of class="android.widget.Toast" usually appears on the current page, so Xpath is used
Positioning mode, it is easy to locate.
