PathMotion
extends Object
java.lang.Object | |
↳ | android.support.transition.PathMotion |
This base class can be extended to provide motion along a Path to Transitions.
Transitions such as ChangeBounds
move Views, typically
in a straight path between the start and end positions. Applications that desire to
have these motions move in a curve can change how Views interpolate in two dimensions
by extending PathMotion and implementing getPath(float, float, float, float)
.
This may be used in XML as an element inside a transition.
<changeBounds>
<pathMotion class="my.app.transition.MyPathMotion"/>
</changeBounds>

Public methods
getPath
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) .
