Textswitcher-text switcher

You can use imageswitcher to implement image switching. The text switching animation can also be implemented by a class called textswitcher, which inherits the viewswitcher class.

Viewswitcher
Contains only child textview. Textswitcher is used to animation the labels on the screen. When settext (charsequence) is called, textswitcher uses an animation to erase the current text and display new text content.
