What is difference between android.R.layout.simple_list_item_1 and android.R.layout.simple_list_item_2

Question

Can anyone explain android.R.layout.simple_list_item_1 and android.R.layout.simple_list_item_2 in arrayadapter in android.

I know in android.R.layout.simple_list_ite

Answer 1

The difference is the following. simple_list_item_1 contains only a TextView, whereas simple_list_item_2 has two inside a subclass of RelativeLayout. These are both taken from Jelly Bean.

simple_list_item_1

simple_list_item_2

According to the docs for ArrayAdapter:

By default this class expects that the provided resource id references a single TextView.

So by default, an ArrayAdapter doesn't automatically fill in multiple TextView instances. You can, however, override the getView() method and fill in the two TextViews that appear in R.layout.simple_list_item_2
