我如何在页面标题中添加图标？我试图添加一个drwable，但是当我使用app时，没有图标，但是文本到图标的位置

   public class SectionsPagerAdapter extends FragmentPagerAdapter {

    public SectionsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        // getItem is called to instantiate the fragment for the given page.
        // Return a PlaceholderFragment (defined as a static inner class below).
        return PlaceholderFragment.newInstance(position + 1);
    }

    @Override
    public int getCount() {
        // Show 2 total pages.
        return 2;
    }
    Drawable myDrawable;
    @Override
    public CharSequence getPageTitle(int position) {
        switch (position) {
            case 0:
                myDrawable = getResources().getDrawable(R.drawable.abc_btn_rating_star_off_mtrl_alpha);
                return ("Messaggi "+myDrawable);
            case 1:
                return "File ";

        }
        return null;
    }
}

getPageTitle()允许您仅配置文本，而不是图标。您可以看到该函数的返回类型为CharSequence。如果要设置图标，则需要手动执行。请检查此问题：Tab icon and text both using android design support library
