您需要使用 addTab()方法

这是示例代码:

private void setUpTab() {
        viewPagerAdapter = new ViewPagerAdapter(getSupportFragmentManager(), this);
         for (int i = 0; i < viewPagerAdapter.getCount(); i++) {
             tabLayout.addTab(
                     tabLayout.newTab()
                             .setText(viewPagerAdapter.getPageTitle(i)));
         }
         tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
        viewPager.setAdapter(viewPagerAdapter);

     }
