我有一个ViewPager包含多个选项卡。在屏幕顶部有一个选项卡指示器（下图中的黑色条）。如何禁用选项卡指示器？
下面是代码（如果需要）：

// ViewPager
ViewPager pager;
TeamTabAdapter tabAdapter;

REvent event;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setTheme(R.style.Backup);
    setContentView(R.layout.activity_team_viewer);

    getSupportActionBar().setBackgroundDrawable(new ColorDrawable(ContextCompat.getColor(getApplicationContext(), R.color.actionbar)));
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    event = (REvent) getIntent().getSerializableExtra("event");
    RTeam team = (RTeam) getIntent().getSerializableExtra("team");
    RForm form = new Loader(getApplicationContext()).loadForm(event.getID());

    tabAdapter = new TeamTabAdapter(getSupportFragmentManager(), event, team, form);
    pager = (ViewPager) findViewById(R.id.pager);

    pager.addOnPageChangeListener(this);

    pager.setAdapter(tabAdapter);
    pager.setCurrentItem(1);
}
