PatternPathMotion

Kotlin |Java

public class PatternPathMotion
extends PathMotion

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.

Summary

XML attributes
`android:patternPathData`	The path string describing the pattern to use for the PathPathMotion.

Public constructors
`PatternPathMotion()` Constructs a PatternPathMotion with a straight-line pattern.
`PatternPathMotion(Context context, AttributeSet attrs)`
`PatternPathMotion(Path patternPath)` Creates a PatternPathMotion with the Path defining a pattern of motion between two coordinates.

Public methods
`Path`	`getPath(float startX, float startY, float endX, float endY)` Provide a Path to interpolate between two points `(startX, startY)` and `(endX, endY)`.
`Path`	`getPatternPath()` Returns the Path defining a pattern of motion between two coordinates.
`void`	`setPatternPath(Path patternPath)` Sets the Path defining a pattern of motion between two coordinates.

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Public constructors

PatternPathMotion

Added in API level 21

public PatternPathMotion ()

Constructs a PatternPathMotion with a straight-line pattern.

PatternPathMotion

Added in API level 21

public PatternPathMotion (Context context, 
                AttributeSet attrs)

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

PatternPathMotion

Added in API level 21

public 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.

Public methods

getPath

Added in API level 21

public 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)`.

getPatternPath

Added in API level 21

public 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.

Related XML Attributes:

android:patternPathData

Returns
`Path`	the Path defining a pattern of motion between two coordinates.

setPatternPath

Added in API level 21

public void setPatternPath (Path patternPath)

Sets 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.
