android - 如何在 Android 的内置图像选择查看器中添加“按钮”以实现“多图像选择功能”

Question

我正在创建将多个选定图像发送到 Web 数据库的 Android 应用程序

我按照https://demonuts.com/select-multiple-images-gallery的教程进行 操作

问题是上面的代码在虚拟模拟器设备上运行良好见下图，其中“2 selected”和“SELECT”显示在虚拟设备上

但是“2 selected”和“SELECT”的上述部分并未显示在实际手机上，
因此我无法使用以下选定图像返回上一个活动，也无法单击“发送”按钮

我猜代码使用 Android 的内置图像选择查看器而不是自定义 xml 浏览器，因此我无法弄清楚如何在该 Android 的内置图像选择查看器上添加“按钮”，
也无法弄清楚我应该在哪里添加“如果我可以将按钮添加到 Android 的内置图像选择查看器，则关于该按钮的 onclicklistener"

或者如果有其他方法可以实现相同的“多图像选择算法”，请详细建议，因为我是 Android 开发新手
