Android UI开发第一篇——android的九宫格式实现

XML代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:columnWidth="90dip"  //列宽
android:stretchMode="columnWidth"

</GridView>
</LinearLayout>

android:numColumns="3" //九宫格的列数 auto_fit时为自动
android:listSelector="@drawable/grid_selector_background" //九宫格的背景，可以找个圆角正方形
