I have some Fragments with TableLayout, is in that order:

1, 2, 3, 4, 5, 6

I used the method viewPager.setOffscreenPageLimit(5) when I create mine viewPager.

So far ok, I don’t want him carrying around all the time Fragments and the seOffscreenPageLimit solved this for me. But I need the Fragment 1 recharge every time you reach it.

Does anyone have a solution for this? or have you ever suffered from something like this? Thank you

  • Can you explain the problem better? setOffscreenPageLimit(5), contrary to what he says, he keeps all the Ragments in memory. What he means by "reload"?

  • Exactly, it keeps all my Fragments in memory, and from what I’ve seen in the life cycle, it never gets into Fragment onCreateView, so far perfect. My problem is, I want to leave all Fragments in memory, I don’t need you logging into onCreateView, but I need Fragment 1 to always log into onCreateView for me to reload my webview.

  • Create a method in the given Fragment and put in it the code that reloads the Webview. Use the answer code of thiagoms83 and when this page is selected call this method.

You can use the setOnPageChangeListener method from Viewpager to know when the user is at position 1:

viewPager.setOnPageChangeListener(new OnPageChangeListener() {

        @Override
        public void onPageSelected(int arg0) {
            //verifique se usuario esta na posicao 0 e atualize o fragment
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {}

        @Override
        public void onPageScrollStateChanged(int arg0) {}
    });

  • I don’t understand where I can implement this, currently I have a setupViewPager and call an Adapter, I put this code on the Adapter?
