Android Navigation Drawer unable to setText in a Fragment from MainActivity -

i trying set gps coordinates on textview of fragment mainactivity can not figure out how this.

i have:

mainactivity.java locationfragment.java

i want update textview in locationfragment mainactivity's onlocationchanged() method.

is chance :

public void onlocationchanged(location location) { lat = (double) (location.getlatitude()); lng = (double) (location.getlongitude()); fragment.updatetext(lat +" "+lng); }

you can utilize interface main objective of fragment re-usability maintained. can implement communication between activity-fragment or fragment-fragment via using next :

android android-activity android-fragments fragment drawer
