Android Intent issue -

i want show details of calculation in activity when click on button. how achieve this. first activity java code is

public void onclick(view v) {    if(v.getid()==r.id.button07)      {         intent intent=new intent(advancedcalculator.this,calculateddata.class);         startactivity(intent);     } 

the calculation want is

string a,b; integer vis; = txtbox3.gettext().tostring(); b = textview1.gettext().tostring(); vis = (integer.parseint(a)*integer.parseint(b))/100; tv.settext(vis.tostring()); 

i want result 'tv' shown in next activity when press submit button. need include calculation.and further steps

any appreciated thanks

in first activity:

public void onclick(view v) {      //put calculation code here      bundle b = new bundle();     b.putstring("answer", youranswer);     //you use putinteger, whichever prefer.      intent intent=new intent(advancedcalculator.this,calculateddata.class);          intent.putextras(b);     startactivity(intent);   } 

in second activity, in oncreate put this:

bundle b = getintent().getextras(); string answer = b.getstring("answer"); 

answer key. used identify want bundle. using unique keys means can pass more 1 value next activity, if want.
