Method Summary

Modifier and Type	Method and Description
static android.graphics.RectF	applyInsets(android.graphics.RectF rect, Insets insets) Calculates a new RectF by applying insets to rect.
static boolean	areIdentical(android.graphics.RectF r1, android.graphics.RectF r2) Determine if two RectF instances are equal.
static android.graphics.RectF	createFromEdges(float w1, float h1, float w2, float h2) Generates a RectF from two height and two width values; the h and w values will be passed into the RectF constructor such that RectF.left <= RectF.right and RectF.top <= RectF.bottom.

Method Detail

areIdentical

public static boolean areIdentical(android.graphics.RectF r1,
                                   android.graphics.RectF r2)

Determine if two RectF instances are equal. Must be used in place of default equality operation due to a bug that exists in older versions of Android: http://stackoverflow.com/questions/13517852/rectf-equals-fails-on-android-versions-below-jelly-bean

Parameters:

r1 - May not be null

r2 - May not be null

Returns:

True if r1 and r2 are identical, false otherwise.

applyInsets

public static android.graphics.RectF applyInsets(android.graphics.RectF rect,
                                                 Insets insets)

Calculates a new RectF by applying insets to rect.

Parameters:

rect -

insets -

Returns:

The RectF created as a result of applying insets, or the passed in instance, if the insets were null.

createFromEdges

public static android.graphics.RectF createFromEdges(float w1,
                                                     float h1,
                                                     float w2,
                                                     float h2)

Generates a RectF from two height and two width values; the h and w values will be passed into the RectF constructor such that RectF.left <= RectF.right and RectF.top <= RectF.bottom.

Parameters:

w1 - width1

h1 - height1

w2 - width2

h2 - height2

Returns:
