Example 5 with RotationMode

use of com.android.launcher3.graphics.RotationMode in project Neo-Launcher by NeoApplications.

the class Utilities method getDescendantCoordRelativeToAncestor.

/**
 * Given a coordinate relative to the descendant, find the coordinate in a parent view's
 * coordinates.
 *
 * @param descendant The descendant to which the passed coordinate is relative.
 * @param ancestor The root view to make the coordinates relative to.
 * @param coord The coordinate that we want mapped.
 * @param includeRootScroll Whether or not to account for the scroll of the descendant:
 *          sometimes this is relevant as in a child's coordinates within the descendant.
 * @param ignoreTransform If true, view transform is ignored
 * @param outRotation If not null, and {@param ignoreTransform} is true, this is set to the
 *                   overall rotation of the view in degrees.
 * @return The factor by which this descendant is scaled relative to this DragLayer. Caution
 *         this scale factor is assumed to be equal in X and Y, and so if at any point this
 *         assumption fails, we will need to return a pair of scale factors.
