Как я могу разработать PagerSlidingTabStrip с изображениями в Android?

Мне также было интересно сделать то же самое, что и вы, наконец, я сделал это для вас.

Импортируйте демо-версию SlidingTabsBasic из примера android-sdk или загрузите его из примеров Google Android из здесь< /а>.

mSlidingTabLayout = (SlidingTabLayout) view.findViewById(R.id.sliding_tabs);
mSlidingTabLayout.setCustomTabView(R.layout.custom_tab, 0);
mSlidingTabLayout.setViewPager(mViewPager);

public CharSequence getPageTitle(int position)
{
    //return "Item " + (position + 1);
    Drawable image = getActivity().getResources().getDrawable(imageResId[position]);
    image.setBounds(0, 0, image.getIntrinsicWidth(), image.getIntrinsicHeight());
    SpannableString sb = new SpannableString(" ");
    ImageSpan imageSpan = new ImageSpan(image, ImageSpan.ALIGN_BOTTOM);
    sb.setSpan(imageSpan, 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    return sb;
}

Что ж, было нетрудно взглянуть на код SlidingTabLayout. Я прокомментировал несколько строк кода. Код говорит сам за себя, я думаю.

Ну, вы можете настроить его в соответствии с вашими потребностями.
