Activity has isDestroyed(), but I can't find the counterpart for Fragment.
I could override onDestroyed() to set a flag for myself but I assume there's an existing solution.
I'm trying to check whether a fragment is destroyed or not in a network response before updating UI in the fragment.
Any help will be greatly appreciated. Thanks!
onCreate(Bundle) called to do initial creation of the fragment. onCreateView(LayoutInflater, ViewGroup, Bundle) creates and returns the view hierarchy associated with the fragment. onActivityCreated(Bundle) tells the fragment that its activity has completed its own Activity.
Since all fragments are destroyed if the activity is destroyed, a simple answer could be calling getActivity(). isDestroyed() returning true if the activity is destroyed, therefore the fragment is destroyed.
These files contain only the onCreateView() method to inflate the UI of the fragment and returns the root of the fragment layout. If the fragment does not have any UI, it will return null.
fragment:fragment:1.1. 0 you can just use onPause() and onResume() to determine which fragment is currently visible for the user. onResume() is called when the fragment became visible and onPause when it stops to be visible.
You can create a Fragment as your parent of other fragments and use following code to check is destroyed functionality.
public abstract class ASafeFragment extends Fragment
{
protected boolean isSafe()
{
return !(this.isRemoving() || this.getActivity() == null || this.isDetached() || !this.isAdded() || this.getView() == null);
}
...
}
or
public static boolean isSafeFragment( Fragment frag )
{
return !(frag.isRemoving() || frag.getActivity() == null || frag.isDetached() || !frag.isAdded() || frag.getView() == null );
}
