I am using 4 fragments inside a ViewPager ,as ViewPager load the previous and next fragment in advance ,and no lifecycle method is called when navigating between fragments. So is there any way to detect when Fragment is actually visible. Thanks in Advance.
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. To enable this behavior in the first ViewPager you have to pass FragmentPagerAdapter.
onStart()The onStart() method is called once the fragment gets visible.
1 Answer. Show activity on this post. You cannot do that, the viewpager requires at least one fragment to the left and one to the right. I suggest you move the onResume() logic to a separate method and call it when the fragment becomes visible.
as per @Matt's answer setUserVisibleHint
is deprecated
so here is alternative way for this.
@Override
public void setMenuVisibility(boolean isvisible) {
super.setMenuVisibility(isvisible);
if (isvisible){
Log.d("Viewpager", "fragment is visible ");
}else {
Log.d("Viewpager", "fragment is not visible ");
}
}
