android:layout_gravity

android:layout_gravity
Gravity specifies how a component should be placed in its group of cells. The default is android.view.Gravity#TOP. See android.widget.LinearLayout#setGravity(int).

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.

android:layout_weight

android:layout_weight
Indicates how much of the extra space in the LinearLayout is allocated to the view associated with these LayoutParams. Specify 0 if the view should not be stretched. Otherwise the extra pixels will be pro-rated among all views whose weight is greater than 0.

May be a floating point value, such as "1.2".
