Known Direct Subclasses |
A Layout that arranges its children in a single column or a single row. The direction of
the row can be set by calling setOrientation()
.
You can also specify gravity, which specifies the alignment of all the child elements by
calling setGravity()
or specify that specific children
grow to fill up any remaining space in the layout by setting the weight member of
LinearLayoutCompat.LayoutParams
.
The default orientation is horizontal.
See the Linear Layout guide.
Also see LinearLayoutCompat.LayoutParams
for layout attributes
