Question

我有Tab布局，其中有两个TabItems。因此，当选择一个tabitem时，下划线来自起点，宽度太大。所以我想根据我的标签文本设置指标宽度，并仅在两个标签项中的文本下显示下划线。

Answer 1

    final  TabLayout tabLayout = (TabLayout) view.findViewById(R.id.varietytaba);
    tabLayout.addTab(tabLayout.newTab().setText("VEG"));
    tabLayout.addTab(tabLayout.newTab().setText("NON VEG"));
    tabLayout.setBackgroundColor(Color.parseColor("#000000"));

    tabLayout.setTabTextColors(Color.parseColor("#FFFFFF"), Color.parseColor("#FFFFFF"));

    final ViewPager viewPager = (ViewPager) view.findViewById(R.id.viewPager_drinka);
    viewPager.setAdapter(new Fragvariety.Pageradapter(getChildFragmentManager(),
            tabLayout.getTabCount()));
    viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
    tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener(){


        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            viewPager.setCurrentItem(tab.getPosition());
            tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#FFFFFF"));
        }
