是否可以在图像视图中获取图像的图像路径？

Question

I have set an image in an image view. Now I want to save this state and need to know the image path of that image. Is there a way to do that?

UPDATE:

// Decode, scale and set the image.
            Bitmap myBitmap = BitmapFactory.decodeFile(selectedImagePath);
            Bitmap scaledBitmap = Bitmap.createScaledBitmap(myBitmap, NEW_WIDTH, NEW_HEIGHT, true);
            myBitmap.recycle();
            myBitmap = null;

            mImageView.setImageBitmap(scaledBitmap);

Not directly, once an image is set on an ImageView it is turned into a Drawable and all else is forgotten. However, you could use tags for this purpose. Any view can have a tag associated with it that represents some metadata about that view. You could do something like:

ImageView iv; //Declared elsewhere
Uri imagePath = Uri.parse("...");
//Set the image itself
iv.setImageURI(imagePath);
//Add the path value as a tag
iv.setTag(imagePath);


//Sometime in the future, retrieve it
Uri path = (Uri)iv.getTag();

You might also consider creating a subclass of ImageView to encapsulate this extra function to help make your code a little easier to read and maintain.
