Toolbar title not in center when Back Button is enable

Question

I'm trying to display my toolbar title in the center and to do it I use the method which is given in this answer :-Toolbar Center title

However, when I enable back button in my activity by following code:

toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mActionBar = getSupportActionBar();
mActionBar.setDisplayHomeAsUpEnabled(true);
mActionBar.setDisplayShowHomeEnabled(true);

The title of toolbar doesn't show up in the center but slightly off-centered towards the right.

How can I achieve centered title without being affected by the back button or menu bar?

Add a TextView inside the Toolbar & don't forget to set the following attribute inside your TextView.

android:layout_marginRight="?android:attr/actionBarSize"

OR

android:layout_marginEnd="?android:attr/actionBarSize"

code snippet:

<android.support.v7.widget.Toolbar
    android:id="@+id/custom_toolbar"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/actionBarSize"
    android:background="@android:color/holo_red_dark">
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="abc"
        android:textColor="@android:color/white"
        android:textSize="20sp"
        android:layout_marginRight="?android:attr/actionBarSize"
        android:gravity="center"/>

</android.support.v7.widget.Toolbar>
