TabLayout selected Tab icon is not selected on start up

Question

I\'m using a TabLayout for Tabbed navigation in my app. I have a really weird issue with it, I have created 4 tabs using this code:

private int[         


        

Answer 1

here is solution, paste this code in you onCreate Activity because using tabs 0 index not triggers directly this is easy way to do

 viewPager.setCurrentItem(1);
    if (viewPager.getCurrentItem()==1)
    {
        viewPager.setCurrentItem(0);
    }

Answer 2

Try this:

tabLayout.getTabAt(yourInitialPosition).getCustomView().setSelected(true);

Answer 3

I used in my tabLayout the xml selector for the icons with the following states:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/icon_ajuda_off"/>
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/icon_ajuda_on"/>
<item android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/icon_ajuda_on"/>
<item android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/icon_ajuda_on"/>

and in the code:

private int[] tabIcons = {R.drawable.ic_tab_sites, R.drawable.ic_tab_help,
        R.drawable.ic_tab_profile, R.drawable.ic_tab_notification, R.drawable.ic_tab_search};

if (tabLayout != null) {
    for (int i = 0; i < 5; i++) {
        tabLayout.getTabAt(i).setIcon(tabIcons[i]);
    }
}

It might help.

The correct answer for tab selection in TabLayout would be:

TabLayout.Tab currentTab = mTabs.getTabAt(selectedTab);
if (currentTab != null) {
    View customView = currentTab.getCustomView();
    if (customView != null) {
        customView.setSelected(true);
    }
    currentTab.select();
}

where currentTab.select() will move the indicator to the selected tab, when customView.setSelected() will make all the items in the custom view set their selected states from the selectors look selected.

Answer 5

Try selecting the tab after you've populated them.

TabLayout tabLayout = setTabLayout();
if (tabLayout != null) {
    for (int i = 0; i < 4; i++) {
        tabLayout.getTabAt(i).setIcon(tabIcons[i]);
    }
    tabLayout.getTabAt(0).select();
}

Answer 6

In my case I only wanted to add the vector drawable to the selector file by it's not working so if you want to use Vector drawable you MUST add them as separated files...

<item android:drawable="@drawable/stnkb_tab_recent_selected_true" android:state_selected="true" />
<item android:drawable="@drawable/stnkb_tab_recent_selected_false" />
