public static class GridLayout.Spec
extends Object

java.lang.Object
	android.support.v7.widget.GridLayout.Spec

Spec规定了一组单元的水平或垂直特性。每个规格。定义沿相应轴的网格索引和对齐。

网格索引是该单元组的前端和后端。有关GridLayout用于网格索引的约定的描述，请参见GridLayout 。

alignment属性指定如何在这个组中对齐单元格。对于行组，这指定了垂直对齐。对于列组，这指定了水平对齐。

使用以下静态方法创建规格：

公共方法(Public methods)
`boolean`	`equals(Object that)` 返回 `true`如果 `class` ， `alignment`和 `span`此规格和所提供的参数的属性是成对相等， `false`否则。
`GridLayout.Alignment`	`getAbsoluteAlignment(boolean horizontal)`
`int`	`hashCode()` 返回对象的哈希码值。

From class java.lang.Object

boolean equals (Object that)

返回 true如果 class ， alignment和 span此规格和所提供的参数的属性是成对相等， false否则。

参数(Parameters)
`that`	`Object`: the object to compare this spec with

返回(Returns)
`boolean`	`true` if the specified object is equal to this `Spec`; `false` otherwise

GridLayout.Alignment getAbsoluteAlignment (boolean horizontal)

参数(Parameters)
`horizontal`	`boolean`

返回(Returns)
`GridLayout.Alignment`

int hashCode ()

返回对象的哈希码值。为了散列表的好处而支持该方法，例如由HashMap提供的HashMap 。

hashCode的总合同是：

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

尽可能合理实用，类Object定义的hashCode方法确实为不同的对象返回不同的整数。（这通常通过将对象的内部地址转换为整数来实现，但Java ^TM编程语言不需要此实现技术。）

返回(Returns)
`int`	a hash code value for this object.
