使用调试器查看在你的代码运行时直接在ImageView上 - 我猜它不是你认为的那个，它根本不包含任何图像。

但我没有涉水通过你的整个项目试图找出你正在做什么的代码 - 如果你想要特定的答案，你需要显示相关的代码片段，而不是将代码转储给我们并说我不能帮助你，所以你帮助我了。



你的问题越好 - 也就是你付出的努力越多 - 我们的回答就越好可以。但只是倾销代码并期望我们趟过它只是粗鲁而且不会让你成为任何朋友......

Use the debugger to look at the ImageView directly while your code is running - I'm guessing it isn't the one you think it is, and it doesn't contain any image at all.
But I'm not wading through your entire project trying to work out where in that code you are doing what - if you want specific answers, you need to show relevant code fragments instead of dumping your code on us and saying "I can't be bothered to help you, so you help me instead."

The better your question - i.e. the more effort you put into it - the better our answers can be. But just dumping code and expecting us to wade through it is just rude and that doesn't make you any friends...
