; you must do so
yourself by calling

| gravity | The desired placement of the object, as defined by the constants in this class. |
|---|---|
| w | The horizontal size of the object. |
| h | The vertical size of the object. |
| container | The frame of the containing space, in which the object will be placed. Should be large enough to contain the width and height of the object. |
| outRect | Receives the computed frame of the object in its container. |
| layoutDirection | The layout direction. |

| w | The horizontal size of the object. |
| h | The vertical size of the object. |
| container | The frame of the containing space, in which the object will be placed. Should be large enough to contain the width and height of the object. |
| xAdj | Offset to apply to the X axis. If gravity is LEFT this pushes it to the right; if gravity is RIGHT it pushes it to the left; if gravity is CENTER_HORIZONTAL it pushes it to the right or left; otherwise it is ignored. |
| yAdj | Offset to apply to the Y axis. If gravity is TOP this pushes it down; if gravity is BOTTOM it pushes it up; if gravity is CENTER_VERTICAL it pushes it down or up; otherwise it is ignored. |
| outRect | Receives the computed frame of the object in its container. |
Apply a gravity constant to an object. This supposes that the layout direction is LTR.

Apply additional gravity behavior based on the overall "display" that an
object exists in. This can be used after
apply(int, int, int, Rect, int, int, Rect)
to place the object
within a visible display. By default this moves or clips the object
to be visible in the display; the gravity flags
DISPLAY_CLIP_HORIZONTAL
and
DISPLAY_CLIP_VERTICAL
can be used to change this behavior.
| gravity | Gravity constants to modify the placement within the display. |
|---|---|
| display | The rectangle of the display in which the object is being placed. |
| inoutObj | Supplies the current object position; returns with it modified if needed to fit in the display. |

Convert script specific gravity to absolute horizontal value.
if horizontal direction is LTR, then START will set LEFT and END will set RIGHT. if horizontal direction is RTL, then START will set RIGHT and END will set LEFT.| gravity | The gravity to convert to absolute (horizontal) values. |
