Remove Or Clear All Fragments From Viewpager

I'm populating view pager through fragments likes this pagerAdapter = new PagerAdapter(getSupportFragmentManager()); mViewPager = (ViewPager) findViewById(R.id.container);

Solution 1:

the fragment was already getting removed and destroyed. the issue was of viewpages.

Only this worked for me

myViewPager.setSaveFromParentEnabled(false);

Cheers !

Solution 2:

Add this method in ViewPagerAdapter and call it when you want to clear fragments from viewPager

publicvoidclear() {
    FragmentTransaction transaction = manager.beginTransaction();
    for (Fragment fragment : mFragmentList) {
        transaction.remove(fragment);
    }
    mFragmentList.clear();
    transaction.commitAllowingStateLoss();
}

Solution 3:

mViewPager : is the view you are using to set you Fragment

mViewPager = (YourViewPager) findViewById(R.id.myPager);

TABLE : is just a Integer list of the position of all my Fragments

publicvoiddestroyAllItem() {
        int mPosition = mViewPager.getCurrentItem();
        int mPositionMax = mViewPager.getCurrentItem()+1;
        if (TABLE.size() > 0 && mPosition < TABLE.size()) {
            if (mPosition > 0) {
                mPosition--;
            }

            for (int i = mPosition; i < mPositionMax; i++) {
                try {
                    Object objectobject = this.instantiateItem(mViewPager, TABLE.get(i).intValue());
                    if (objectobject != null)
                        destroyItem(mViewPager, TABLE.get(i).intValue(), objectobject);
                } catch (Exception e) {
                    Log.i(TAG, "no more Fragment in FragmentPagerAdapter");
                }
            }
        }
    }

    @Override
    publicvoiddestroyItem(ViewGroup container, int position, Object object) {
        super.destroyItem(container, position, object);

        if (position <= getCount()) {
            FragmentManager manager = ((Fragment) object).getFragmentManager();
            FragmentTransaction trans = manager.beginTransaction();
            trans.remove((Fragment) object);
            trans.commit();
        }
    }

Solution 4:

With ViewPager2 (1.0.0) and FragmentStateAdapter I also found the current view not to be recreated after updating the data set using notifyDataSetChanged, even when the data corresponding to the current view is changed. Apparently, notifyDataSetChanged doesn't perform a very thorough investigation of what has been changed and assumes the current view to be still correct.

The workaround I found was to simply set the same adapter that I had already set for the previous data set again:

viewPager2.setAdapter(myFragmentStateAdapter);

Apparently, setting an adapter makes it flush the cached views, which makes very good sense of course. Luckily, it doesn't check whether it's the same adapter.
