senario like

fragment of navigationdrawer(default fragment)->tablayout fragment(position=0)->button inside tablayout position=0->click on button it's call navigationdrawer(default fragment) method.

please me solve out problem.

there 3 solutions:

1. use localbroadcastreceiver , send intent 1 fragment , listen @ another

2. use eventbus library

3. use activity callback listener. @ fragment can take current activity @ onattach method
