how can i update next page in viewpager with fragment?

Question

I made android program, and it has a viewpager with three fragment. So, you can handle three screen with your finger and here comes problem. After i did something in a first page, then i want to refresh or update second fragment.

For example, once i input some text in a first page, then in a second page this text appear. If i input text again, then in a second page also textview has changed. Please give me some information to handle viewpager and fragment.

As i know, viewpager load page and next page. Then how can i update next page in viewpager?

I have more or less answered the same question here: Android: Get Fragment Reference from ViewPager/FragmentStatePagerAdapter

In short, you need to update some model data that the next page will read upon onResume(). This way the page will show the updated data.

you should make the info static which you want to share in your first fragment and then use that static data in your second fragment.Actually im out of station so i just show you the demo code to get you on path:).Like this:---

 class FirstFragment extend Fragment{
 public static String text;

 /// then assign the text according to your events and you can access this in second   fragment
 }

class Second Fragment extends Fragment{
  onCreateView(....){
        TextView your_textview = (TextView)findViewById(R.id.your_textview);
        your_textview.setText(FirstFragment.text);
      }
}

how can i update next page in viewpager with fragment?
