Pass data between activities in a single android app -
i have situation stated below:
__> b(setup page)------------> d(account settings) *all users have / | same layout / (has 10 rows/users) / (click 1 of account/row, highlight) / (once row selected, , click done, data saved in d / jumped , passed c. a(welcome page) \ \__> c(remote page) above illustration of overall program~
i not know how pass data d through b c~ can guide me? code in c incomplete because has other function , class not related it.
code:
// code b: public class accountsetup extends activity { tablerow tablerow1, tablerow2, tablerow3, tablerow4, tablerow5, tablerow6, tablerow7, tablerow8, tablerow9, tablerow10; view border1, border2, border3, border4, border5, border6, border7, border8, border9, border10;
