java - Why notifyDataSetChanged not working on some devices? -


helo,

i've got viewpager 5 fragments.

my problem is, calling

 viewpager.getadapter().notifydatasetchanged();

doesn't work on devices.

for example, on bq aquaris mobile phone works fine. refreshes 5 fragments.

but on huawei honor mobile phone refresh first fragment, , others left are.

how can avoid problem?

bq aquaris android version is: 7.1.1

huawei honor android version is: 7.0

you can try set viewpager.setoffscreenpagelimit 5 (see https://developer.android.com/reference/android/support/v4/view/viewpager.html#setoffscreenpagelimit(int) more information).

but not recommended hold lot of pages in memory. alternative use viewpager.addonpagechangelistener , update corresponding fragment.
