android - How to communicate data between two fragments in a navigation drawer -
i have navigation drawer contains different fragments (each item display fragment) , i'd pass data fragment another.(i have 1 activity contain navigation drawer in have list of fragments).
i have tried many solutions (bundle , intent) couldn't solve problem.
can 1 me pleaaase.
this first fragment : package com.tutecentral.navigationdrawer;

thank you.
when click inside navigationdrawer, can use setarguments() method declare datas via bundle follows:
// int id = 1; myfragment newfragment = new myfragment(); bundle args = new bundle(); args.putint("arg_data_id", id); newfragment.setarguments(args); // replace , commit fragmenttransaction then, inside fragment, use getargument() method following:
bundle arg = getarguments(); int id_pass = arg.getint("arg_data_id"); // id_pass = 1; however, maybe can find useful tips topic: communicating other fragments.
update:
well, tried make example code but, it's hum.. hard ;).
you don't receive argument because in
selectitemmethod, don't send argumentmenufragment (but switch how do, you're on right way). try separatly send argument in otherbundlewhen click onbuttonvalidatepricesinsettingnot send or anything. created, value stored it, , nothing.. it's not relatedfragmenttransaction.inside
menu, try receive this:log.i("bundlebundlebundle", getarguments().getstring("price_"+"pizza",default));but think better with:
log.i("bundlebundlebundle", getarguments().getstring("price_pizza"));
you should:
first (in mainactivity) = get value of clicked spinner mainactivity setting fragment, create bundle , set value fragment inside selectitem method follows:
switch(...) { case 2: frag = new menu(); // value of spinner selected here! this: string text = ((spinner) findviewbyid(r.id.spinnersetting)). getselecteditem().tostring(); // string named "spinner_position", how can after args.putstring("spinner_position", text); break; ... } frag.setarguments(args); // replace fragment second (in menu) = receive argument follows:
// receive using name "spinner_position", that's it. nothing else. string text_spinner = getarguments().getstring("spinner_position");
