在viewpager刷新后，TabLayout图标消失

Question

Hello Can someone help me

This is my android source code

private int[] tabIcons = {
        R.drawable.ic_tab_gallery,
        R.drawable.ic_tab_facebook,
        R.drawable.ic_tab_instagram,
        R.drawable.ic_tab_album
};

tabLayout = (TabLayout)findViewById(R.id.tabLayout);
viewPager = (ViewPager)findViewById(R.id.viewpager);


setupViewPager(viewPager);
tabLayout.setupWithViewPager(viewPager);
setupTabIcons();

And this is how i put icon in TabLayout item

private void setupTabIcons() {
    tabLayout.getTabAt(0).setIcon(tabIcons[3]);
    tabLayout.getTabAt(1).setIcon(tabIcons[1]);
    tabLayout.getTabAt(2).setIcon(tabIcons[2]);
    //tabLayout.getTabAt(3).setIcon(tabIcons[3]);
}

But after refreshing my viewPager all my tabLayout icons disappear. Thanks for your help.

Answer 1

I had the same issue and I reassign the icons to tablayout after viewpager refresh.Like

for (int i = 0; i < tabLayout.getTabCount(); i++) {
        tabLayout.getTabAt(i).setIcon(imageResId[i]);
        tabLayout.getTabAt(i).setText(textResId[i]);
    }

Another approach is to override getPageTitle method of Viewpager adapter as mentioned in this post .
