i have activity contains button , starts fragment when clicked.but need finish current activity when starting fragment.how possible?i tried calling finish() after starting fragment.but not working.

android.app.fragmentmanager fm = getfragmentmanager(); detailfragment dialog_fragment = new detailfragment("events",name,id); dialog_fragment.show(fm, "detailscreen"); finish();

call getactivity().finish(); fragment finish activity.

however, careful. getactivity() null. in case, don't call finish(). activity destroyed.
