如何在Android中使用TabItem通过TabLayout

最近google在supportDesign中添加了android.support.design.widget.TabItem,因为documentation说：

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.

但是当我将TabItems添加到我的TabLayout时：

没有显示任何内容(事实上Tabs的位置存在,但Icon / Text不存在).有谁知道如何通过xml使用TabItem？

最佳答案

基于this答案,TabItem与tabLayout.setupViewPager有冲突,图标消失.为了使它工作,你应该实现两个方法,如下面的,并避免使用setupViewPager方法：

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) {

                }
            });
