Alternative for the onResume() during Fragment switching

Question

onResume() method won't get called when we switch between fragments more than one time. So, is there any better way to handle resume operation?

Answer 1

Code follows:

Step: 1

Create Interface:

public interface YourFragmentInterface {
    void fragmentBecameVisible();
}

Step: 2

Attach Listner In setOnPageChangeListener:

mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(final int position, final float v, final int i2) {
        }

        @Override
        public void onPageSelected(final int position) {
            YourFragmentInterface fragment = (YourFragmentInterface) mPagerAdapter.instantiateItem(mViewPager, position);
            if (fragment != null) {
                fragment.fragmentBecameVisible();
            } 
        }

        @Override
        public void onPageScrollStateChanged(final int position) {
        }
    });

Step: 3

Implement Interface In Your Fragment:

public class yourActivity extends SherlockFragment implements YourFragmentInterface{
    @Override
    public void fragmentBecameVisible() {
          System.out.println("TestFragment");
    }
}

Implement this listner in all yor fragment activity fragmentBecameVisible() this method call during Fragment switching.

Thanks.
