How to set the divider between Tabs in TabLayout of design support library?

Android Problem Overview

I am using the new android.support.design.widget.TabLayout of v7-appcompat library, and found a problem, there is no way to set the divider between the tabs, dont know if there is.

I have successfully configured the pager adapter and the tabs are looking good but cant set the divider between the tabs.

I want this type of tabs

Tab1 | Tab2 | Tab3

but currently its showing

Tab1  Tab2  Tab3

My xml is

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" >

        <include layout="@layout/toolbar" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tablayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/shape_tabbar_background"
            app:tabIndicatorColor="@android:color/white"
            app:tabIndicatorHeight="4dp" />
    </android.support.design.widget.AppBarLayout>

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

</android.support.design.widget.CoordinatorLayout>

I am adding tabs by this

viewPager = (ViewPager) findViewById(R.id.viewpager);
	viewPager.setOffscreenPageLimit(2);
	adapter = new TabAdapterLoginActivity(getSupportFragmentManager(),
	        titles);
	viewPager.setAdapter(adapter);
	tabLayout = (TabLayout) findViewById(R.id.tablayout);
	tabLayout.setupWithViewPager(viewPager);

Solution 1 - Android

TabLayout is actually HorizontalScrollView and it's first child is LinearLayout.

So just use below code to add dividers

    View root = tabLayout.getChildAt(0);
    if (root instanceof LinearLayout) {
        ((LinearLayout) root).setShowDividers(LinearLayout.SHOW_DIVIDER_MIDDLE);
        GradientDrawable drawable = new GradientDrawable();
        drawable.setColor(getResources().getColor(R.color.separator));
        drawable.setSize(2, 1);
        ((LinearLayout) root).setDividerPadding(10);
        ((LinearLayout) root).setDividerDrawable(drawable);
    }

Below is the sample screen shot

Solution 2 - Android

There is a way to add divider by using Tab setCustomView method:

TabLayout tabLayout = (TabLayout) findViewById(R.id.tablayout);
tabLayout.setupWithViewPager(viewPager);

for (int i = 0; i < tabLayout.getTabCount(); i++) {
      TabLayout.Tab tab = tabLayout.getTabAt(i);
      RelativeLayout relativeLayout = (RelativeLayout) 
            LayoutInflater.from(this).inflate(R.layout.tab_layout, tabLayout, false);
      
      TextView tabTextView = (TextView) relativeLayout.findViewById(R.id.tab_title);
      tabTextView.setText(tab.getText());
      tab.setCustomView(relativeLayout);
      tab.select();
}

Tab custom layout with divider (tab_layout.xml):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

<!-- Tab title -->
<TextView
    android:id="@+id/tab_title"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:textColor="@drawable/tab_item_selector"/>

<!-- Tab divider -->
<View
    android:layout_width="1dp"
    android:layout_height="match_parent"
    android:layout_alignParentLeft="true"
    android:background="@android:color/black" />
</RelativeLayout>

Set TabLayout tab horizontal padding to 0dp:

<android.support.design.widget.TabLayout
        android:id="@+id/tablayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/shape_tabbar_background"
        app:tabIndicatorColor="@android:color/white"
        app:tabIndicatorHeight="4dp"

        app:tabPaddingStart="0dp"
        app:tabPaddingEnd="0dp" />

And a selector for tab title text color when it's selected (tab_item_selector.xml):

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:color="@color/abc_primary_text_material_dark" />
    <item android:state_focused="true" android:color="@color/abc_primary_text_material_dark" />
    <item android:state_pressed="true" android:color="@color/abc_primary_text_material_dark" />
    <item android:color="@color/abc_secondary_text_material_dark" />
</selector>

I do not think it is possible though unless during Tab creation you specify a customView and add your divider so for instance; a TextView and you explicitly TextView.setCompoundDrawablesWithIntrinsicBounds(0, 0,(int)id_of_a_divider, 0);

like you try to detect if its the first Tab,

if(firstTab){
    tabLayout.getTabAt(0).getCustomView()
    .setCompoundDrawablesWithIntrinsicBounds(0, 0,(int)id_of_a_divider, 0);
    //some little casting
}else if(lastTab){
  //dont get any
   tabLayout.getTabAt(index).getCustomView()
    .setCompoundDrawablesWithIntrinsicBounds(0,0,0, 0);
 else{
    //the rest takes two sides,
     tabLayout.getTabAt(index).getCustomView()
    .setCompoundDrawablesWithIntrinsicBounds((int)id_of_a_divider
       , 0,(int)id_of_a_divider, 0);

i hope you, get my idea

Solution 4 - Android

hi you can try this as workaround what i did as follow :-

1-create normal tablayout.

2-make the mode MODE_FIXED

2-adding it in framellayout and above it add linear layout horizonytal.

3-add buttons in horizontal layout as the number of your tabs and make the buttons equals in size layout_wight=1 for each button.

4-make the buttons background transparent.

3-add spertator between the buttons in horizinoal linearlayout layout via view or anyview and specify the widht as 0.5dp or what ever thick you want.

4-you can add yor clicks on buttons or change the button to any oter view that not handle the clicking so the tab under it will take the click action :).

it might be ugly solutuions but it works perfect and do the job

another hint if you want to change the background of the selected tab you can make the indicator hieght in tablayout style equale the actual height of the tablayout.

        <item name="tabIndicatorColor">#50000000</item>
        <item name="tabTextAppearance">@style/MyCustomTabTextAppearance</item>
        <item name="tabIndicatorHeight">60dp</item>
        <item name="tabSelectedTextColor">#222222</item>

Solution 5 - Android

Not Best but alternative way i used for current.

In Main.Xml

<android.support.design.widget.TabLayout
    android:id="@+id/tabs"
    style="@style/Base.Widget.Design.TabLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/master_color"
    app:elevation="0dp"
    app:tabMode="scrollable"
    app:tabPaddingEnd="2dp"
    app:tabPaddingStart="0dp"
    app:tabSelectedTextColor="@color/white"
    app:tabTextColor="#82c6e6" />

i am using fragment and do in onCreate() like

if (savedInstanceState == null) {
    replaceFragment(fragmentOne);
}

Set Tab

private void setupTabLayout() {

    fragmentOne = new FragmentOne();
    fragmentTwo = new FragmentTwo();

    allTabs.addTab(allTabs.newTab().setText("CURRENT YEAR"), true);
    allTabs.addTab(allTabs.newTab().setText("2015"));
    allTabs.addTab(allTabs.newTab().setText("2014"));
    allTabs.addTab(allTabs.newTab().setText("2013"));
    allTabs.addTab(allTabs.newTab().setText("2012"));
    allTabs.addTab(allTabs.newTab().setText("2011"));

    //Hide Indicator
    allTabs.setSelectedTabIndicatorColor(getResources().getColor(android.R.color.transparent));
    //Set Custom tab Background
    for (int i = 1; i < allTabs.getTabCount(); i++) {
        TabLayout.Tab tab = allTabs.getTabAt(i);
        RelativeLayout relativeLayout = (RelativeLayout)
                LayoutInflater.from(getActivity()).inflate(R.layout.tab_layout, allTabs, false);
        tvTabText = (TextView) relativeLayout.findViewById(R.id.tab_title);
        View view = (View) relativeLayout.findViewById(R.id.deviderView);

        tvTabText.setText(tab.getText());
        tab.setCustomView(relativeLayout);

        if (i == 0) {
            view.setVisibility(View.GONE);
            tab.select();
        }
    }

}

Solution 7 - Android

try to use this code to set divder in TabHost mTabHost.getTabWidget().setDividerDrawable(R.Color.blue);

Solution 8 - Android

One way to add a custom divider is to set it programmatically:

tablayout.getTabWidget().setDividerDrawable(R.drawable.yourdivider image name);

Make sure however, you call this before you set the content of the tabs. It would crash on me if I called it after.

you can also use this line if this doesn't work

if(Build.VERSION.SDK_INT >= 11)
    tablayout.getTabWidget().setShowDividers(TabWidget.SHOW_DIVIDER_MIDDLE);
