Я использую ViewPager в своем приложении, он содержит 7 фрагментов. Каждый фрагмент содержит множество изображений. Я хочу отображать счетчик загрузки, пока фрагмент загружает изображения с помощью Glide (изображения не из Интернета! Нет необходимости в загрузке). Загрузка изображений занимает около полсекунды, и кажется, что есть задержка. Поэтому я хочу знать, как отображать индикатор выполнения Spinner.
MainActivity.java:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
if (isRTL())
viewPager.setCurrentItem(7);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
tabLayout.setLayoutDirection(View.LAYOUT_DIRECTION_LTR);
}
tabLayout.setupWithViewPager(viewPager);
}
public static boolean isRTL() {
return isRTL(Locale.getDefault());
}
public static boolean isRTL(Locale locale) {
final int directionality = Character.getDirectionality(locale.getDisplayName().charAt(0));
return directionality == Character.DIRECTIONALITY_RIGHT_TO_LEFT ||
directionality == Character.DIRECTIONALITY_RIGHT_TO_LEFT_ARABIC;
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
if (isRTL()) {
// The view has RTL layout
adapter.addFragment(new S7(), getString(R.string.stage7));
adapter.addFragment(new S6(), getString(R.string.stage6));
adapter.addFragment(new S5(), getString(R.string.stage5));
adapter.addFragment(new S4(), getString(R.string.stage4));
adapter.addFragment(new S3(), getString(R.string.stage3));
adapter.addFragment(new S2(), getString(R.string.stage2));
adapter.addFragment(new S1(), getString(R.string.stage1));
adapter.addFragment(new Intro(), getString(R.string.Introduction));
} else {
// The view has LTR layout
adapter.addFragment(new Intro(), getString(R.string.Introduction));
adapter.addFragment(new S1(), getString(R.string.stage1));
adapter.addFragment(new S2(), getString(R.string.stage2));
adapter.addFragment(new S3(), getString(R.string.stage3));
adapter.addFragment(new S4(), getString(R.string.stage4));
adapter.addFragment(new S5(), getString(R.string.stage5));
adapter.addFragment(new S6(), getString(R.string.stage6));
adapter.addFragment(new S7(), getString(R.string.stage7));
}
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);

Где я могу разместить ProgressBar и как?
Спасибо большое!!!
picasso
, но это все еще можно сделать с помощьюGlide
