How do I find the ID of a fragment? Alternatively, how do I give the fragment an ID?
android, findviewbyid
Solution
Provided you keep a reference to your FragmentStatePagerAdapter and to the index of the Fragment in view, you can call getItem(int position) on your FragmentStatePagerAdapter, which will return the Fragment.
Problem
(First, I'm aware this question has been asked plenty of times, but I haven't found an applicable answer) I have a fragment created as such: ``` inflater.inflate ( R.layout.fragment_task_ongoing, container, false ); ``` What I'd like, is to use findFragmentById in the FragmentActivity, like this: ``` TaskActiveFragment f = ( TaskActiveFragment ) getSupportFragmentManager ().findFragmentById ( R.id.fragment_task_ongoing ); ``` Unfortunately, this returns null. The apparent reason is that the id used as a parameter, is the id of the RelativeLayout being inflated, and not the Fragment. First lines of the layout: ``` <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/fragment_task_ongoing" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingLeft="16dp" android:paddingRight="16dp" > ``` So, how do I find out what ID the fragment has? If it doesn't have an ID, how do I give it one? Programatically? XML? Edit: My fragments are added to a FragmentStatePagerAdapter, which is then added to a ViewPager.
