Android : Adding space in between tab layout

I am working on an Android project in which I am using TabLayout to show tabs as shown in the image below. As you can see in the screenshot, the tabs are all aligned on the left side. How can I add spaces properly so the three tabs fill out the entire width instead of getting clubbed in on left side. Thank you.

Screenshot :

enter image description here

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"
    android:orientation="vertical">
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="50dp">

for (int a= 0; a< tabLayout.getTabCount(); a++) {           
    View tabView = LayoutInflater.from(context)
            .inflate(LayoutInflater.from(this), R.layout.item_main_tabview, null, false);

    tabView.setLayoutParams(new TableLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
    tabView.setPadding(0, 0, 0, 0);
    tabLayout.getTabAt(a).setCustomView(tabViewBinding.getRoot());
}

Thus You can add space between tabs in tablayout

Please remove below line in your activity file

    tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

and Change your tablayout

<android.support.design.widget.TabLayout
    android:id="@+id/tab_layout"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:layout_marginTop="0dp"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    app:tabMode="fixed"
    app:tabGravity="fill"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:fillViewport="false" />
