推荐答案

好吧，您正在将图像路径保存到数据库，而不是图像本身.当数据从数据库返回以填充适配器时，它只是带有路径的字符串，并且不知道它应该是图像.

Well, you are saving the image path to the database and not the image itself. When the data comes back from the database to fill the adapter, it is just a string with the path, and has no idea that it is supposed to be an image.

这很明显...但是我能做什么呢?我想在我的数据网格中保存图片...这将在我的数据库中...:(

aha it is clear... but what do i can in order to do this? i want image in my datagrid... which will be in my database...:(
