具有自定义图标的TabLayout在启动时不会更改图标

Question

I have TabLayout and ViewPager in my layout, pretty standart. And I'm using custom views for my tabs. In Activity onCreate method I call:

ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
setupViewPager(binding.viewpager);
binding.tabs.setupWithViewPager(binding.viewpager);
tabLayout.getTabAt(0).setCustomView(R.layout.tab).setText(R.string.tab_home)
                .setIcon(R.drawable.tab_home_icon).setTag(HOME_TAG); 
tabLayout.getTabAt(1).setCustomView(R.layout.tab).setText(R.string.tab_games)
                .setIcon(R.drawable.tab_games_icon).setTag(GAMES_TAG);

And here is how mu drawables look like:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/tab_home_active" android:state_selected="true" />
    <item android:drawable="@drawable/tab_home" />
</selector>

I want to show orange icon, if tab is selected and grey otherwise. And everything works fine except for very beginning. If I navigate from tab to tab once - everything is fine:

But when activity just started - Home tab is not "selected":

I've already tried to select tab pragmatically - didn't help.

Answer 1

Here is an answer:

binding.tabs.getTabAt(0).getCustomView().setSelected(true);

or even

int selectedTabPosition = binding.tabs.getSelectedTabPosition();
binding.tabs.getTabAt(selectedTabPosition).getCustomView().setSelected(true);

It was not on purpose, I just dig a little in android sources.

Answer 2

Try :

Viewpage.setcurrentItem(0) at the end
