What is ViewHolder Pattern?

What is ViewHolder Pattern?
Approach used to store a set of views so they can be efficiently accessed and reused when needed. The purpose of the ViewHolder class is to save the views.
What is the purpose of the ViewHolder Pattern?
Avoid repeated use of findViewById() to get references to views.
When saved in a ViewHolder object the references are available immediately.
What are its benefits?
Avoid loss of performance due to repeated use findViewById() .
