java.lang.Object | ||
↳ | android.transition.PathMotion | |
↳ | android.transition.PatternPathMotion |
A PathMotion that takes a Path pattern and applies it to the separation between two points. The starting point of the Path will be moved to the origin and the end point will be scaled and rotated so that it matches with the target end point.
This may be used in XML as an element inside a transition.

The path string describing the pattern to use for the PathPathMotion.
Must be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character.
This may also be a reference to a resource (in the form
"@[package:]type:name
") or
theme attribute (in the form
"?[package:][type:]name

PatternPathMotion (Path patternPath)
Creates a PatternPathMotion with the Path defining a pattern of motion between two coordinates. The pattern will be translated, rotated, and scaled to fit between the start and end points. The pattern must not be empty and must have the end point differ from the start point.
Parameters | |
---|---|
patternPath |
Path :
A Path to be used as a pattern for two-dimensional motion.
|
Path getPath (float startX, float startY, float endX, float endY)
Provide a Path to interpolate between two points (startX, startY)
and
(endX, endY)
. This allows controlled curved motion along two dimensions.
Parameters | |
---|---|
startX |
float :
The x coordinate of the starting point. |
startY |
float :
The y coordinate of the starting point. |
endX |
float :
The x coordinate of the ending point. |
endY |
float :
The y coordinate of the ending point. |
Returns | |
---|---|
Path |
A Path along which the points should be interpolated. The returned Path
must start at point (startX, startY) , typically using
moveTo(float, float) and end at (endX, endY) .
|
Path getPatternPath ()
Returns the Path defining a pattern of motion between two coordinates. The pattern will be translated, rotated, and scaled to fit between the start and end points. The pattern must not be empty and must have the end point differ from the start point.
