+ * 仿微信--------------------------发现
+ *
+ *    详细信息封装
+ *
+ *    添加点击使用的是 GestureDetector 将Container或者Widget包装起来;
+ *
+ *    (1)onTap: 点击时的回调,需要调用setState(() {}刷新;
+ *    (2)onTap: 点击时的回调,需要调用setState(() {}刷新;
+ *    (3)onTapCancel: 手势取消调用,比如点击后继续滑动到其他地方,这时候不需要跳转,但颜色需要改回白色,需要调用setState(() {}刷新;
+ *    (4)使用Navigator进行界面的跳转,没有参数的话直接调用push()方法;
+ *    (5)固定用法:使用MaterialPageRoute创建回调;
