Android动态改变GridView的值【安卓进化二十二】

最近感觉GridView的用法比较灵活，比如写一些动态改变的东西，更新显示效果比较明显，所以我写了一个demo，选中球后，点击确定显示选中的球在主页面，点击重置，则选中的球都被清空。这个效果还是比较不错的！希望给大家启迪。项目图片我没有上传，有问题的请留言，想要源码的请留言，转载请标明出处：

程序的主页面：点击button按钮弹出dialog页面：

点击确定后的效果，点击重置如

选球，球的颜色会发生变化第二张图片的效果，球没有选中的效果

</LinearLayout>

二、ball_grid_dialog.xml布局文件中的代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
     <TextView
	   android:id="@+id/gridviewtitle"
	   android:layout_width="fill_parent"
	   android:layout_height="wrap_content"
	   android:gravity="center_horizontal"
	   android:text="@string/ball_textview"
	   android:textSize="20dip"
	   android:background="#00000000"
	   />
	<View 
	    android:layout_width="fill_parent" 
	    android:layout_height="2dip"
		android:background="#FF909090" />
	<GridView 
	    android:id="@+id/red_ball_grid" 
	    android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:horizontalSpacing="5dip"
		android:verticalSpacing="10dip"
		android:numColumns="7"
		android:gravity="center" />
	<View 
	    android:layout_width="fill_parent" 
	    android:layout_height="2dip"
		android:background="#FF909090" />
	<GridView 
	    android:id="@+id/blue_ball_grid"
		android:layout_width="match_parent" 
		android:layout_height="wrap_content"
		android:horizontalSpacing="5dip"
		android:verticalSpacing="10dip"

	<View 
	    android:layout_width="fill_parent"
	    android:layout_height="2dip"
