android - Manipulate a tab fragment during runtime -

-

i got 3 fragments each on seperate tab. on 1 tab want have fragment in card-style. 1 row should [ ________ ________ +]. after pressing +button want second identical row appear. how achive that? professional way manipulate tagfragments during runtime? how can implement trancisions?

i got it. can add additional rows by: 

@override     public void onclick(view v) {         switch (v.getid()) {         case r.id.imagebuttonadd:             if(i==0){                 raisecounterbyone();                 counter.settext(counterstart.tostring());                 test = getactivity().findviewbyid(r.id.testview3);                 test.setvisibility(view.visible);                 i++;             } else if(i==1){                 raisecounterbyone();                 counter.settext(counterstart.tostring());                 test = getactivity().findviewbyid(r.id.testview4);                 test.setvisibility(view.visible);                 i++;             }             break;         case r.id.imagebuttoncancel2:             log.d("","close");             test = getactivity().findviewbyid(r.id.testview3);             test.setvisibility(view.gone);             i--;             break;         case r.id.imagebuttoncancel3:             log.d("","close");             test = getactivity().findviewbyid(r.id.testview4);             test.setvisibility(view.gone);             i--;             break;         default:             break;         }     }

is there better way more flexible? array or loop? there opportunity put views array? want set maximum number of rows can added. furthermore index each row later use.
