PathMotion

Kotlin |Java

public abstract class PathMotion
extends Object

java.lang.Object
↳	androidx.transition.PathMotion

Known direct subclasses

ArcMotion, PatternPathMotion

ArcMotion	A PathMotion that generates a curved path along an arc on an imaginary circle containing the two points.
PatternPathMotion	A PathMotion that takes a Path pattern and applies it to the separation between two points.

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 constructors

PathMotion

public PathMotion (Context context, 
                AttributeSet attrs)

Parameters
`context`	`Context`
`attrs`	`AttributeSet`

Public methods

getPath

public abstract 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 `Path.moveTo(float, float)` and end at `(endX, endY)`.
