 Known Indirect Subclasses
|
An interface that can be implemented by Views to provide scroll related APIs.
| Public Methods | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
Compute the horizontal extent of the horizontal scrollbar's thumb within the horizontal range. | |||||||||||
Compute the horizontal offset of the horizontal scrollbar's thumb within the horizontal range. | |||||||||||
Compute the horizontal range that the horizontal scrollbar represents. | |||||||||||
Compute the vertical extent of the vertical scrollbar's thumb within the vertical range. | |||||||||||
Compute the vertical offset of the vertical scrollbar's thumb within the horizontal range. | |||||||||||
Compute the vertical range that the vertical scrollbar represents. | |||||||||||
Compute the horizontal extent of the horizontal scrollbar's thumb within the horizontal range. This value is used to compute the length of the thumb within the scrollbar's track.
The range is expressed in arbitrary units that must be the same as the
units used by computeHorizontalScrollRange() and
computeHorizontalScrollOffset().
The default extent is the drawing width of this view.
