我的代码有问题，我必须将图像上传到firebase存储，我需要图像来自图库和相机，图库中的图像都可以，但来自相机的图像是给出问题，在imageView中加载并发送到数据库的图像是黑色的。有谁知道如何解决这个问题，或者你知道任何其他加载图像的方法吗？

您用于启动相机应用程序的意图仅返回thumbnail image，您可以从返回的数据中获取该文件：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
...
mImageView.setImageBitmap(imageBitmap);
}
}
如果要获取完整大小的图像，则必须创建一个文件来保存图像，为文件创建URI，并将URI作为额外添加到intent中。这是described in the documentation。
