标准重力常数，小孩提供给其父母。 定义子视图应如何在其封闭布局中定位在X轴和Y轴上。
必须是以下常量值中的一个或多个（用'|'分隔）。
| Constant | Value | 描述 |
|---|---|---|
top |
0x30 | Push object to the top of its container, not changing its size. |
bottom |
0x50 | Push object to the bottom of its container, not changing its size. |
left |
0x03 | Push object to the left of its container, not changing its size. |
right |
0x05 | Push object to the right of its container, not changing its size. |
center_vertical |
0x10 | Place object in the vertical center of its container, not changing its size. |
fill_vertical |
0x70 | Grow the vertical size of the object if needed so it completely fills its container. |
center_horizontal |
0x01 | Place object in the horizontal center of its container, not changing its size. |
fill_horizontal |
0x07 | Grow the horizontal size of the object if needed so it completely fills its container. |
center |
0x11 | Place the object in the center of its container in both the vertical and horizontal axis, not changing its size. |
fill |
0x77 | Grow the horizontal and vertical size of the object if needed so it completely fills its container. |
clip_vertical |
0x80 | 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. |
clip_horizontal |
0x08 | 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. |
start |
0x00800003 | Push object to the beginning of its container, not changing its size. |
end |
0x00800005 | Push object to the end of its container, not changing its size. |
这对应于全局属性资源符号 layout_gravity 。
int UNSPECIFIED_GRAVITY
gravity表示重力未明确指定。
常量值：-1（0xffffffff）
int gravity
与这些布局参数相关联的View应用的重力。
默认值是 UNSPECIFIED_GRAVITY ，它被FrameLayout视为 Gravity.TOP | Gravity.START 。
