购物车 ListView 包含了EditText的问题，最终解决换RecyclerView来做，哈哈哈哈
写这篇文章主要是为了记录EditText，这个EditText的处理真的让人头疼啊。解决一个问题又出现一个问题，我花了3天的时间尽然没有解决，我也是醉了！！！
最终是使用RecyclerView，
先把最终的放在这里：然后写一下ListView 里面的包含EditText的两步处理
要注意的是setTag://注意tag一定要在最上面，就是要在设置监听前面
MainActivity：

记录一下：
0：只要在清单文件中设置android:windowSoftInputMode="adjustPan"
1：在item里面设置android:descendantFocusability="beforeDescendants"
