ViewHolder Pattern with BaseAdapter in Android

viewholder-pattern-featured

Hello Friends, today we are going see an example of ViewHolder Pattern with BaseAdapter in Android. I am sharing this code example because few weeks ago I was working on a project and after completing code, I have analyzed my code using “Inspect Code…” feature of Android Studio which is available under Analyze menu. And I found performance issue in my code (see screenshot below). Then I googled and found this solution which I am sharing now.

without-viewholder-pattern
Unconditional layout inflation from view adapter: Should use View Holder pattern (use recycled view passed into this method as the second parameter) for smoother scrolling

Let’s Code Now

MainActivity.java

activity_main.xml

MyBaseAdapter.java

list_item.xml

Item.java
