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.
