Android UI GridLayout (Grid layout)

Description: The grid layout is added after 4.0 layout, with Tablelayout a bit like, but more useful, it divides the container into a rows*columns grid, each grid is a component bit, but by setting the component bit occupy more than one row/column.
Similarly, there is a component called the GridView, which is similar in function and name, but the GridView uses adapter to populate the component bits, and the GridLayout is much simpler.
According to Csdn Bo main studyboyjlu4 (blog address: http://blog.csdn.net/studyboyjlu4) View, The difference between the GridView and the GridLayout is similar to the difference between the ListView and the LinearLayout.

GridLayout has two types of properties to focus on:

1 properties of the GridLayout itself

Description: This type of property is set for GridLayout itself, primarily for rows and columns, and for the way it is set.
The attribute table is as follows:

Properties	Correspondence Method	Property Description
Android:columncount	Setcolumcount (int)	Set the maximum number of columns for a layout
Android:rowcount	Setrowcount (int)	Set the maximum number of rows for a layout
Android:alignmentmode	Setailgnmentmode (int)	Set the layout to its way (alignbounds: to subassembly view boundary; Alignmargins: to subassembly view margins;)
Android:columnorderpeserved	Setcolumorderpreserved (Boolean)	Set whether the container retains column ordinals
Android:roworderpeserved	Setroworderpeserved (Boolean)	Sets whether the container retains row numbers
Android:usedefaultmargins	Setusedefaultmargins (Boolean)	Sets whether the container uses the default page margins

2 Properties for sub-components within a container

Description: This type of property is set for subcomponents in GridLayout, and you can set the size and placement of the component in the grid.
The attribute table is as follows:

Properties	Correspondence Method	Property Description
Android:layout_gravity	setgravity (int)	Set how the component occupies the space of its owning grid
Android:layout_column		Set the component in the first column of the container
Android:layout_row		Set the component line in the container
Android:layout_columnspan		The Setup component occupies several columns
Android:layout_rowspan		The Setup component occupies a few lines

The layoutgravity here is a bit different from the general layoutgravity, where the placement is relative to the owning mesh, not to the layout parent container.
