android viewpagerindicator calling getPageTitle() too many times

Question

I am using viewpagerindicator as part of my android application. getPageTitle of fragmentAdapter is getting called too many number of times on every slide of a page. I verified it with sample application provided as part of viewpagerindicator.

Sample application provied as part of viewpagerindicator has just 4 fragments/pages. But after every slide, getPageTitle is getting called almost 10 to 15 times for each position. Logger statement is attached with output.

Is there any way to avoid this?

 @Override
public CharSequence getPageTitle(int position) {
    Log.d("SAMPLE","Title Getting called for "+position);
  return TestFragmentAdapter.CONTENT[position % CONTENT.length];
}

Answer 1

It works as it supposed . The adapter load always two pages in advance (so it need the title for the current, previous and next page). If you want to avoid this beahviour you can try calling setOffscreenPageLimit(0) on your viewpager instance
