如何解决我无法在两个不同的图像视图中加载两个不同的图片
会发生什么：
实际情况：
- 如果用户将图片上传到Image View_1中，则Image View_1和Image View_2会更改为同一张图片。
- 如果用户将图片上传到Image View_2中，则Image View_2和Image View_1将更改为同一张图片。

解决方法
您的代码不完整，但似乎您将{strong> 2 ValueEventListener附加到UsersReference。因此，每次您上传任何图像时，两个ValueEventListener都会被调用。尝试在单个ValueEventListener中创建一些检查条件，以更新每个ImageView
