MovementMethod

public 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.
