I have a ViewPager2 and a TabLayout on one of the screens and they are linked together with TabLayoutMediator. When TalkBack is enabled on the device, I need either of them to read out the page number when page is changed. e.g. page 1 of 9 and etc.
Does anyone know how to do this?
You can announce the page number by registerning ViewPager2.OnPageChangeCallback and override the onPageSelected()
Then use: a View to announce a Talkback with announceForAccessibility()
mViewPager.registerOnPageChangeCallback(new ViewPager2.OnPageChangeCallback() {
@Override
public void onPageSelected(int position) {
myView.announceForAccessibility("Page number: " + position));
}
});
With TabLayout
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
myView.announceForAccessibility("Page number: " + tab.getPosition()));
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
