## XML attributes
### android:layout_gravity
Standard gravity constant that a child supplies to its parent. Defines how the child view should be positioned, on both the X and Y axes, within its enclosing layout.
Must be one or more (separated by '\|') of the following constant values.
| Constant | Value | Description |
|-------------------|--------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| bottom | 50 | Push object to the bottom of its container, not changing its size. |
| center | 11 | Place the object in the center of its container in both the vertical and horizontal axis, not changing its size. |
| center_horizontal | 1 | Place object in the horizontal center of its container, not changing its size. |
| center_vertical | 10 | Place object in the vertical center of its container, not changing its size. |
| clip_horizontal | 8 | Additional option that can be set to have the left and/or right edges of the child clipped to its container's bounds. The clip will be based on the horizontal gravity: a left gravity will clip the right edge, a right gravity will clip the left edge, and neither will clip both edges. |
| clip_vertical | 80 | Additional option that can be set to have the top and/or bottom edges of the child clipped to its container's bounds. The clip will be based on the vertical gravity: a top gravity will clip the bottom edge, a bottom gravity will clip the top edge, and neither will clip both edges. |
| end | 800005 | Push object to the end of its container, not changing its size. |
| fill | 77 | Grow the horizontal and vertical size of the object if needed so it completely fills its container. |
| fill_horizontal | 7 | Grow the horizontal size of the object if needed so it completely fills its container. |
| fill_vertical | 70 | Grow the vertical size of the object if needed so it completely fills its container. |
| left | 3 | Push object to the left of its container, not changing its size. |
| right | 5 | Push object to the right of its container, not changing its size. |
| start | 800003 | Push object to the beginning of its container, not changing its size. |
| top | 30 | Push object to the top of its container, not changing its size. |
