The Snackbar does not allow you to set a custom layout. However, as Primoz990 suggested you can get the Snackbar's View. The getView function returns the Snackbar.SnackbarLayout, which is a horizontal LinearLayout object whose children are a TextView and a Button. To add your own View to the Snackbar, you just need to hide the TextView, and add your View to the Snackbar.SnackbarLayout.
// Create the Snackbar
Snackbar snackbar = Snackbar.make(containerLayout, "", Snackbar.LENGTH_LONG);
// Get the Snackbar's layout view
Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) snackbar.getView();
// Hide the text
TextView textView = (TextView) layout.findViewById(android.support.design.R.id.snackbar_text);
textView.setVisibility(View.INVISIBLE);
// Inflate our custom view
View snackView = mInflater.inflate(R.layout.my_snackbar, null);
// Configure the view
ImageView imageView = (ImageView) snackView.findViewById(R.id.image);
imageView.setImageBitmap(image);
TextView textViewTop = (TextView) snackView.findViewById(R.id.text);
textViewTop.setText(text);
textViewTop.setTextColor(Color.WHITE);
//If the view is not covering the whole snackbar layout, add this line
layout.setPadding(0,0,0,0);
// Add the view to the Snackbar's layout
layout.addView(snackView, 0);
// Show the Snackbar
snackbar.show();
