Re: [android-developers] Notifying the fragment when it is currently selected in a viewpager

2012-09-29 Thread vinay kumar
we can achieve that by creating interface.

e.g

*public* *class* SampleFragment *extends* ListFragment {

*private* OnItemSelectedListener listener;



*public* *interface* OnItemSelectedListener {

*public* void *onItemSelected*(int index);

}



*public* void *setOnItemSelectedListener*(OnItemSelectedListenerlistener
) {

*this*.listener = listener;

}



@Override

*public* void *onListItemClick*(ListView l, View v,

int position, long id) {

listener.*onItemSelected*(position);

}




Activity source code

*public* *class* MyActivity *extends* Activity

*implements* ItemFragment.OnItemSelectedListener {


@Override

*public* boolean *onCreate*(Bundle bundle) {

*// ...*

SampleFragment item = *new* *SampleFragment*();

item.*setOnItemSelectedListener*(*this*);

*// ...*

}



*public* void *onItemSelected*(int index) {

*// ...*

}

*// ...*

}

Hope this snippet helps you. Good Luck

[android-developers] Notifying the fragment when it is currently selected in a viewpager

2012-09-29 Thread Raneez
I use ViewPager loaded with fragments in it .The *onResume()* method of 
each fragments does some logic and so i get problems when the adjacent 
fragments(left and right) to the currently selected page are also loaded to 
provide smooth scrolling between the pages. 

Does the fragment recieve any *callbacks* when it get actually selected?
