What is the difference between ArrayAdapter , BaseAdapter and ListAdapter

喜欢而已 提交于 2019-11-27 00:47:58

When you are extending the Base adapter class you need to implement all the methods like getCount() , getId() etc. ArrayAdapter is a class which can work with array of data. You need to override only getview() method. ListAdapter is a an interface implemented by concrete adapter classes. BaseAdapter is an abstract class whereas

How to handle multiple countdown timers in ListView?

别来无恙 提交于 2019-11-26 18:58:58
I have a listview (with a custom list adapter), I need to display a countdown on every row. For example, if my list contains 4 items, I will have 4 rows. At this point, I need to handle 4 different countdowns (one for each row) because time is different. So far, I'm handling it the following way : in the Custom List Adapter, inside getView() method I create a new CountDownTimer and display remaining time inside TextView. But the problem is that it slows the activity a lot, I can't even scroll correctly in the worst cases (because each time a row is displayed, it creates a new CountDownTimer).
