android - Getting the values from the different fragments from ViewPager -

i developing application fragments being generated dynamically.

private void setupviewpager(viewpager viewpager) {     adapter = new viewpageradapter(getsupportfragmentmanager());     (int = 0; < sequence_no.size(); i++)      {         adapter.addfragment(fragmenttwo.newinstance(i,(i+1)));     }     viewpager.setadapter(adapter); } 

now suppose there 3 fragments got generated. generated fragments have different widgets edittext, spinner etc. mannage have 1 flag notifies me 1 displayed(spinner or edittext).

i have 1 button in activity upon click need values fragments bu how getting value first fragment only.

i putting wrong sample on here know wrong keeping reference purpose.

below code on submit button click values array list.

if (fragmenttwo.ed_complain != null)      {         values.add(fragmenttwo.ed_complain.gettext().tostring());     }     if (fragmenttwo.cb_complain != null)      {         values.add(fragmenttwo.cb_complain.gettext().tostring());     }     if (fragmenttwo.spinner_complain != null && fragmenttwo.spinner_complain.getselecteditem() != null)      {         values.add(fragmenttwo.spinner_complain.getselecteditem().tostring());     } 

please suggest me need fetching values fragments.

you can solve problem using way. create interface , implement in each fragments. using interface can value specific fragment.

for example , create interface

public interface igetvalue{ string getedittextvalue(); } 

now, if each fragment implements interface each fragment have implements getedittextvalue() method , can return edittext value of implemented method. use :

@override public string getedittextvalue() {      return your_edit_text.gettext().tostring(); } 

now, if want edittext value fragment1 in activity, use line of code:

string valuefromfragment1= fragment1instance.getedittextvalue();
