Design Library TabLayout, tab indicator bouncing after scroll

Question

EDIT The latest design libraries fixed this issue

compile 'com.android.support:design:+'

I am working with the TabLayout in two instances, PagerAdapter and FragmentStatePagerAdapter. In both cases the tab indicator bounces, when swiped between pages. The tab indicator doesn't bounce when clicking tab's to change pages.

I am not sure if it is an error on my part, it is a known issue, or part of the guidelines. If you need more code, or the other example I will post it.

FragmentStatePagerAdapter

    mViewPager.setAdapter(new FragmentStatePagerAdapter(getSupportFragmentManager()) {
        @Override
        public Fragment getItem(int position) {
            LogMeal log = mLogMealAdapter.getItem(position);
            return MealViewFragment.newInstance(log.getId());
        }

        @Override
        public CharSequence getPageTitle(int position) { // Tab text
            LogMeal logMeal1 = mLogMealAdapter.getItem(position);
            String s;
            if (logMeal1.getMealName().toString().trim().length() > 12) {
                s = logMeal1.getMealName().substring(0, 12) + "..";
            } else {
                s = logMeal1.getMealName();
            }
            return s;
        }

        @Override
        public int getCount() {
            return mLogMealAdapter.getCount();
        }
    });

    tabs.setTabTextColors(Color.parseColor("#80ffffff"), Color.parseColor("#ffffff"));
    if (mLogMealAdapter.getCount() == 1) {
        tabs.setTabMode(TabLayout.MODE_FIXED);
    } else {
        tabs.setTabMode(TabLayout.MODE_SCROLLABLE);
    }
    tabs.setupWithViewPager(mViewPager);
    mViewPager.setCurrentItem(position);

Answer 1

I had a similar problem recently.
My workaround:

1) Change tabs.setupWithViewPager(mViewPager); for

    \\ use own OnPageChangeListener 
    mViewPager.addOnPageChangeListener(new MyPageScrollListener(mTabLayout));  

    \\ Manually add tabs, for example:  
    mTabLayout.addTab(mTabLayout.newTab().setText(mViewPager.getAdapter().getPageTitle(0)));
    mTabLayout.addTab(mTabLayout.newTab().setText(mViewPager.getAdapter().getPageTitle(1)));  

    \\ use own OnTabSelectedListener  
    mTabLayout.setOnTabSelectedListener(new MyOnTabSelectedListener());  

2) Add implementation for custom listeners

 private class MyPageScrollListener implements ViewPager.OnPageChangeListener {
    private TabLayout mTabLayout;

    public MyPageScrollListener(TabLayout tabLayout) {
        this.mTabLayout = tabLayout;
    }

    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {
        if(mTabLayout != null) {
            mTabLayout.getTabAt(position).select();
        }
    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
}

private class MyOnTabSelectedListener implements TabLayout.OnTabSelectedListener {
    @Override
    public void onTabSelected(TabLayout.Tab tab) {
        int position = tab.getPosition();
        if (mViewPager.getCurrentItem() != position) {
            mViewPager.setCurrentItem(position, true);
        }
    }

    @Override
    public void onTabUnselected(TabLayout.Tab tab) {

    }

    @Override
    public void onTabReselected(TabLayout.Tab tab) {

    }
}

I hope it helps.
