How use TabItem through TabLayout in Android

Question

Recently google added android.support.design.widget.TabItem in supportDesign as documentation said:

TabItem is a special 'view' which allows you to declare tab items for a TabLayout within a layout. This view is not actually added to TabLayout, it is just a dummy which allows setting of a tab items's text, icon and custom layout.

But when I add TabItems to my TabLayout:

 <android.support.design.widget.TabLayout
         android:layout_height="wrap_content"
         android:layout_width="match_parent">

     <android.support.design.widget.TabItem
             android:text="@string/tab_text"/>

     <android.support.design.widget.TabItem
             android:icon="@drawable/ic_android"/>

 </android.support.design.widget.TabLayout>

Nothing displayed (in fact place of Tabs exist but Icon/Text not). Does any one knows How to use TabItem through xml?

Based on this answer, TabItem with tabLayout.setupViewPager have conflict and Icons disappear. To make it work you should implement two methods like following and avoid using setupViewPager method:

tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                pager.setCurrentItem(tab.getPosition());
            }

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

            }

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

            }
        });

pager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
                @Override
                public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

                }

                @Override
                public void onPageSelected(int position) {
                    tabLayout.getTabAt(position).select();
                }

                @Override
                public void onPageScrollStateChanged(int state) {

                }
            });
