一、概述

GridView(网格视图)是按照行列的方式来显示内容的，一般用于显示图片，图片文字等内容，比如实现十六宫格，九宫格，四宫格等，用GridView是首选，也是最简单的。

android:gravity：设置此组件中的内容在组件中的位置。可选的值有：top、bottom、left、right、center_vertical、fill_vertical、center_horizontal、fill_horizontal、center、fill、clip_vertical可以多选，用“|”分开。

android:horizontalSpacing：两列之间的间距。

android:numColumns：设置列数。

android:stretchMode：缩放模式。

android:verticalSpacing：两行之间的间距。

二、效果图

三、Demo

item.xml

主布局中一个Grideview就可以
