Android textview can only animate the entire textview, not each text. Even with textswitcher, it is difficult to achieve the effect I want.

So choose a custom one. The general idea is: inherit the ViewGroup. When setting text, each text is a textview. Start the animation of each textview at a fixed time.

Define a CTextView that inherits the ViewGroup:

Main implementation code:

A method settext (string text, final animation, animation, int duration) is provided externally. Text is the string to be displayed, animation is the animation of each character, and duration is the playback interval of character animation.

The method is implemented as follows:
