Android UI开发第一篇――android的九宫格式实现

今天在devdiv论坛里看到有坛友问到九宫格的实现，我把我在项目中用的经验分享一下，九宫格用gridview实现代码如下：代码下载地址：http://www.devdiv.com/thread-39455-1-1.html

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
