Java.lang.IllegalStateException: The application PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged android

Question

I am trying to use a static class to pass value to a view instead of using intent as I have to pass a large amount of data. Sometimes I get this error and couldn\'t find out wha

Answer 1

I think your DataResult class is not necessary.

According to your comment you are getting the error while you are updating the data set. I think you are getting data from some REST API or another web service. Then assign the data you gets from the API to a temporary Array List and update that temporary array list while you are getting new data. Don't touch the mListA variable until you finish receiving data. After complete getting data from the API assign the temporary array list you used to mListA directly in one line.

mListA = tmpList;

Then again call

mList = mListA;
pagerAdapter.notifyDataSetChanged();

This should solve your error.
