Q:

How to display images from firebase into recyclerview?

My images unable to be displayed, no error but images not showing. pls help how to display these urls in my apps

A:

First, store the full uri in your database. It will be something like this:
gs://yourdatabasehere.appspot.com/IMG_9837.JPG

or
https://firebasestorage.googleapis.com/v0/b/yourdatabasehere/IMG%29837.JPG?alt=media&token=b6c9153f-7d7c-4b05-a60e-7c7d113733ae

In your code, once you retrieve full uri from database, just use Glide or Picasso to display the image:
Picasso.with(this)
        .load(photoUri)  // full uri retrieved from database
        .placeholder(R.mipmap.ic_no_image) //optional
        .error(R.mipmap.ic_no_image) //optional        
        .into(imageView1);
