问题 I have some problems with my custom ArrayAdapter . I have two different layouts which I apply to the list item depending on an object value. Every time I scroll some of the items change where R.layout.layout1 should be applied, use R.layout.layout2 or the other way. I thought of some problems on caching the layouts in the XML file.

I use ViewPager to display these pages. I don't want to keep all the Fragments in memory, so I decided to use FragmentStatePagerAdapter (My adapter class extends these class). Let's say 3rd tab is selected. Then, when I go for example to the first tab, Fragment for this tab should be created from scratch (that's fine, it

问题 I know this has been asked many times but I still have yet to find a solution I really like. Can someone please suggest the most elegant way to do what I'm trying to do: I have two Listviews which I currently have in a LinearLayout (vertical).

There was a problem with the color not disappearing after I removed the
