Detect when fragment becomes visible
android, android-fragments
Solution
EDIT: As pointed out in the comments, `setUserVisbileHint()` does not get called automatically, but by the FragmentPageAdapter when used in a ViewPager.
For the scenario described in the question, `onHiddenChanged(boolean hidden)` http://developer.android.com/reference/android/app/Fragment.html#onHiddenChanged(boolean) is suitable. As stated in the documentation, the method gets called every time the Fragments hidden state changes, but not on the initial setup of the Fragment.
You could use `setUserVisibleHint()` http://developer.android.com/reference/android/support/v4/app/Fragment.html#setUserVisibleHint(boolean)
if `isVisibleToUser`is set to `true`the fragment should be displayed.
Problem
Why not a duplicate: Suggested post only works for a viewpager, or when onResume is called. I have a listfragment and a detailfragment. The detail fragment is opened when a list item is clicked. I accomplish this by hiding the listfragment and I showing the detailfragment. When the user goes back, he returns to the listfragment. How can I detect when the user gets back to my fragment, or when my fragment is visible? Please note that I would like to keep using .hide() and show() and that I am looking for a listener or a onVisible to check when the fragment becomes visible, and not a method to check if it is visible.
