how display progress dialog before starting activity (i.e., while activity loading data) in android?

you should load data in asynctask , update interface when data finishes loading.

you start new activity in asynctask's onpostexecute() method.

more specifically, need new class extends asynctask:

public class mytask extends asynctask<void, void, void> {   public mytask(progressdialog progress) {     this.progress = progress;   }    public void onpreexecute() {     progress.show();   }    public void doinbackground(void... unused) {     ... loading here ...   }    public void onpostexecute(void unused) {     progress.dismiss();   } }

then in activity do:

progressdialog progress = new progressdialog(this); progress.setmessage("loading..."); new mytask(progress).execute();

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
