I want restore fragment or do not re-oncreate it when re-back to the fragment

Question

I use ActionBar with 3 swipe-tabs.

First-Tab : get a ListView from data of my server when onCreate() & onResume().

Second-Tab : get a ListView from data of my server when onCreate()

Third-Tab : get a some data of my server when onCreate()

Here is a question, When I swipe to Third-Tab and re-back to First-Tab, First-Tab's Fragment is going to onCreate() -> so re-downloading data from my server, and It looks uneffective...

How can I keep my fragment? Please help...

Answer 1

Try to use setOffscreenPageLimit method:

mViewPager.setOffscreenPageLimit(3);

It works for me.

Answer 2

Write this code in all the three fragments you have. This will allow your fragment to inflate the view when its not already inflated.

            if (view != null) {
            ViewGroup parent = (ViewGroup) view.getParent();
            parent.removeView(view);
        } else {
            //inflate your view here
        }
