I keep seeing “focused” and hearing about “focusing” within the development of Android apps. My question is: What is focusing, and how is it applied within Android apps? Is it important? What can you do with it?
I’m sorry if this has been asked, I looked but didn’t see anything that clearly explained it. I’ve looked the the Android development guide, but I couldn’t find a decent explanation of what it is and how it works.
Focus is simply giving a specific view “focus”, or attention.
One example of using focus is if you have an
EditTextViewand you want a user to be able to type into it as soon as it is displayed, you would give focus to that EditTextView and the keyboard would automatically be displayed in accordance to typing in that view.
