Android动态改变GridView的值【安卓进化二十二】

来源：互联网 发布：怎么发送淘宝店铺链接 编辑：程序博客网 时间：2024/06/08 04:01
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
