TypewriterView

An Android view that can be used to sequentially animate typing and deleting one character at a time. Pausing and enqueuing arbitrary Runnables is also possible. Inspired by Devunwired @ Stackoverflow (see http://stackoverflow.com/questions/6700374/android-character-by-character-display-text-animation).

An EditText view has been used as base to get a blinking cursor. This has the drawback that the user could edit the text while it is animating. Minimum changes to the code are required to instead use a TextView as base if that is an issue.

Example

TypewriterView typewriterView = (TypewriterView) view.findViewById(R.id.typewriter);
