MovementMethodpublic interface MovementMethod | Provides cursor positioning, scrolling and text selection functionality in a {@link TextView}.
The {@link TextView} delegates handling of key events, trackball motions and touches to
the movement method for purposes of content navigation. The framework automatically
selects an appropriate movement method based on the content of the {@link TextView}.
This interface is intended for use by the framework; it should not be implemented
directly by applications.
