How to update the ListView of a Fragment from another Fragment?
You can access another Fragment
by its tag:
// find your fragment
YourFragment f = (YourFragment) getSupportFragmentManager().findFragmentByTag("yourFragTag");
// update the list view
f.updateListView();
The tag of your Fragment
is set when it is attached to a container layout:
FragmentManager fm = getSupportFragmentManager();
fm.beginTransaction().replace(R.id.frameBuy, YourFragment.newInstance(), "yourFragTag").commit();
So when you click your Button
, find the Fragment
you want to refresh by its tag, and then call your refresh method.
IF you are using a ViewPager
, this is how to get the Fragments
tag:
/**
* Gets the fragment tag of a fragment at a specific position in the viewpager.
*
* @param pos the pos
* @return the fragment tag
*/
public String getFragmentTag(int pos){
return "android:switcher:"+R.id.yourViewPagerId+":"+pos;
}
