![]() |
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>

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. |
