[置顶] Android GridView

本文介绍通过GridView实现九宫格的布局：
activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" >    <GridView  xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gridview" android:layout_width="match_parent" android:layout_height="match_parent" android:numColumns="auto_fit" android:verticalSpacing="10dp" android:horizontalSpacing="10dp" android:columnWidth="90dp" android:stretchMode="columnWidth" android:gravity="center" ></GridView></LinearLayout>

子项布局文件:
sub_item.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="match_parent" android:paddingBottom="4dip" >    <ImageView  android:id="@+id/itemImage" android:layout_centerHorizontal="true" android:layout_width="wrap_content" android:layout_height="wrap_content" />    <TextView  android:id="@+id/itemText" android:text="TextView01" android:layout_centerHorizontal="true" android:layout_below="@+id/itemImage" android:layout_width="wrap_content" android:layout_height="wrap_content" /></RelativeLayout>

GridViewActivity.java

十分基础，记录下来作为笔记同时也是一个总结的过程
