java - Dynamic User Input Forms -

i want collect information user. let's say, want collect information age , gender each of family members.

how this, in form, given not know family size, when prompted, can input number of family members. screen shows, form list family member 1:
age:
gender:
family member 2:
age
gender
, on. 1 big list, scroll down app input information. , submit button @ end submit form me. don't know how handle unknown number of edittext forms etc , how extract info each.

if show me how code snippets.

there many different way mention 1 of them:

-start have layout of edittext , button. size of family question -layout viewpager -layout fragement, how u want form example 2 edittext (age , gender) , 1 button

-create fragment.java class , inflate fragment layout inside it

now on main activity set first layout size of family layout.

for example enters 4.

now open new activity viewpager layout content.

 int size = 4;  arraylist<fragments> lf = new arraylist<fragment>(); 

create fragments loop

for(int count;0 count<size; count ++){      fragment f = new fragment();     lf.add(f); } 

now create pageradapter passing "lf" it

you can set text every button accordingly

string text; if(pagenumber == size-1) //means last page   text= "finish"; else    text = "next"; 

then

button.settext(text); 

update clarification

1. firstfragment.xml should have want in form (2 edittexts , 1 button)
2. main_pager.xml has viewpager
3. create mainactivity.java class setcontentview(r.layout.main_pager);
4. in oncreate() find viewpager , give viewpager instance.
5. after above loop explained according size of family

6. now call setadapter on viewpager . ex: vpager.setadapter(new fragmentadapter(getfragmentmanager(), lf));

7. here fragmentadapter class.

   public class fragmentadapter extends fragmentpageradapter{       private list<fragment> fragments;        public fragmentadapter (fragmentmanager fm, list<fragment> fragments) {           super(fm);               this.fragments = fragments;       }        @override       public fragment getitem(int position) {           return this.fragments.get(position);       }        @override       public void destroyitem (viewgroup container, int position, object object)       {           super.destroyitem(container, position, object);       }        @override       public int getcount() {          return this.fragments.size();       }  }
