performing calculations in photosactivity.class(which in first tab(photoes)) activity , pass result string songsactivity.class (which in second tab(songs)) use string further calculations.
can suggest way archieve that? thanx inadvance!!
the idea of communication between parent activity , child using associated tags in case "photoes" , "songs".
for example: if need pass string tab "photoes" parent activity.
1)you need create public method in parent activity call following child
((androidtablayoutactivity)getparent()).myfunctionname("string value"); 2)to pass value specific child,e.g. "songs", have create public method within child activity , call parent using it's tag.
public void myfunctionname(string str){ activitytab1 activity = (activitytab1) getlocalactivitymanager().getactivity("tab1"); activity.takethisvalue(str); } you may need validation make sure activity instances not null
if(activity !=null) //do stuff
