Interface MovementMethod

All Known Implementing Classes:

ArrowKeyMovementMethod, BaseMovementMethod, LinkMovementMethod, ScrollingMovementMethod

@ParametersAreNonnullByDefault
public interface MovementMethod

Provides cursor positioning, scrolling and text selection functionality in a TextView.

The 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 TextView.

This interface is intended for use by the framework; it should not be implemented directly by applications.
