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"     xmlns:app="http://schemas.android.com/apk/res/com.google.android.gx5weather"     android:orientation="vertical"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:layout_weight="1.0"     android:background="@drawable/bg"     ><ImageView android:id="@+id/ImageView01"           android:layout_width="wrap_content"           android:layout_height="wrap_content"           android:layout_gravity="center_vertical"           android:background="@drawable/top"></ImageView>  <GridView xmlns:android="http://schemas.android.com/apk/res/android"       android:id="@+id/gridview"     android:layout_width="wrap_content"       android:layout_height="wrap_content"     android:numColumns="3"     android:verticalSpacing="30dip"     android:horizontalSpacing="10dip"     android:columnWidth="90dip"  //列宽    android:stretchMode="columnWidth"     android:gravity="center"    android:listSelector="@drawable/grid_selector_background"></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
