ImageView has the setImageResource method. What is the getImageResource method?

Question

Using intents to click on an element from the RecyclerView, with a small image on each element, to go to another screen/activity which will show the enlarge picture.

There is no method that will give you ImageResource.

You can check ImageView source code. They just convert your ImageResource to Drawable and use it. So you have a getter method for Drawable imageView.getDrawable();. This is only what you can get. There is no getter for getting resource id from Drawable object.

 if (mResource != 0) {
            try {
                d = mContext.getDrawable(mResource);
            } catch (Exception e) {
                Log.w(LOG_TAG, "Unable to find resource: " + mResource, e);
                // Don't try again.
                mResource = 0;
            }
        }

Solution 1 From ref

If you want pass Image to another Activity, you can do this.

When you set ImageView resource in Adapter then set a Tag on this.

imageView0.setTag(R.drawable.apple);

Now when you want get that id when user click, then only do

private int getDrawableId(ImageView iv) {
    return (Integer) iv.getTag();
}

Solution 2

If you are one setting ImageView resource, then you would have this resource integer in your List?, so when user click then get resource again like

yourList.get(getAdapterPosition).getImageId();

You can programmatically set your first ImageView's tag to the resource id, and then retrieve it later with getTag() to set as the resource id of the new ImageView.

For instance:

//First set your original image tag...
ImageView original; //The original ImageVew
Integer resId = R.drawable.resource; //The original resource
original.setTag(resId); //Add your resource id to the tag

//Then, to get the resource id...
Integer resId = original.getTag();
