How can I get the integer value of R.id.image?

Question

While using recycler views, I just want to pass the string values of resource id's of the images, but I know that it can't be done using the usual way, like we cannot pass a string in setImageResource(). But is there a way to convert the R.id.anyImage into its integer value?

what do you mean by passing string values? do you have string value like the name of the image? — akhilesh0707, Sep 10 '20 at 18:59
if you have a resource name as a string you can get the resource id using `getIdentifier` — akhilesh0707, Sep 10 '20 at 19:02

Unfortunately, there is no getImageResource() or getDrawableId(). But, You can create simple workaround by using the ImageView tags.

In onCreate():

imageView0 = (ImageView) findViewById(R.id.imageView0);
imageView1 = (ImageView) findViewById(R.id.imageView1);
imageView2 = (ImageView) findViewById(R.id.imageView2);

imageView0.setTag(R.drawable.apple);
imageView1.setTag(R.drawable.banana);

imageView2.setTag(R.drawable.cereal);

Then, if you like, you can create a simple function to get the drawable id:

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

Too easy.
