我正在为自闭症儿童在Android Studio中创建一个时间表/时间表应用程序，他们可以使用"活动图像"组织他们的一天，可以"拖放"到每天总共5个"活动时段"（星期一，星期二等）。
我按如下方式命名每个图像位置：
星期一： 1A， 1B， 1C， 1D， 1E星期二： 2A， 2B， 2C， 2D， 2E星期三： 3A， 3B， 3C， 4D， 3E星期四： 4A， 4B， 4C， 4D， 4E星期五： 5A， 5B， 5C， 5D， 5E星期六： 6A， 6B， 6C， 6D， 6E星期日： 7A， 7B， 7C， 7D， 7E
我已经成功地对其进行编码以将"活动图像"放置在位置 1A 中，但是我不确定如何为其余位置对其进行编码。 我尝试复制并粘贴之前用于其他位置的代码，但是当"拖放"图像时，它会将同一图像复制到所有编码的位置。

我稍微更改了您的代码，请尝试一下，但请听听注释并尝试将代码减少一点。
