How to save ViewPager FORM data onSwipe to next pager android

Here, I have an Activity with viewpager which has FragmentA , FragmentB, FragmentC and FragmentD in the adapter.

All Fragments has FORM data. When I swipe from FragmentA to FragmentB, I have to save the form data of FragmentA before FragmentB is visible and in the same way when swipe from FragmentB to FragmentC I have to save the form data of FragmentB before FragmentC is visible.

Is this possible? If yes, How to do this?

You can save those details in Shared preferences while you swiping to next fragment. For swiping 

            viewPagerBanner.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            private static final float thresholdOffset = 0.5f;
            private boolean scrollStarted, checkDirection, check;

            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
                if (checkDirection) {
                    if (thresholdOffset > positionOffset && position == 0) {
                        check = true;
                    } else {
                        check = false;
                    }
                    checkDirection = false;
                }
            }

            @Override
            public void onPageSelected(int position) {
                currentPosition = position;
            }

            @Override
            public void onPageScrollStateChanged(int state) {

                // You can save current form fields here
                }

            }
        });

Shared Preferences 

SharedPreferences sharedHead = context.getSharedPreferences("UniqueName", Context.MODE_PRIVATE);    
SharedPreferences.Editor editor = sharedHead.edit();
editor.putInt("name", "Developer");
editor.apply();

To read those data Last fragment

String name = sharedHead.getInt("name", "noName");

I hope this may help you. Thanks
