Title not centered in Android Toolbar widget with customview added


I am trying to create a wearable app where I need to add a custom layout to toolbar ,which contains TextView in relative layout with attribute android:layout_center_in_parent set to true.But the problem is the TextView does not appear in center of ToolBar. Can anyone help me how to display the TextView in center for ToolBar .
I used the used the below code to add customview for Toolbar and my layouts as below :

android.support.v7.widget.Toolbar toolbar = ( android.support.v7.widget.Toolbar)findViewById(R.id.toolbar);
        toolbar.setTitle("");
    //    toolbar.setContentInsetsAbsolute(0,0);
        setSupportActionBar(toolbar);

        LayoutInflater mInflater= LayoutInflater.from(getApplicationContext());
        View mCustomView = mInflater.inflate(R.layout.toolbar_custom_view, null);
        toolbar.addView(mCustomView);


My activity_main.xml

<?xml version="1.0" encoding="utf-8"?>

        app:layout_box="all">
        <include
            android:id="@+id/toolbar"
            layout="@layout/toolbar" />
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/framelayout"
        >
    </FrameLayout>
    </LinearLayout>
</android.support.wearable.view.BoxInsetLayout>


toolbar.xml

toolbar_custom_view.xml
=======================

<?xml version="1.0" encoding="utf-8"?>


<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Patient List"
    android:id="@+id/title"
   android:layot_center_in_parent="true"
    android:gravity="center"

    />

</RelativeLayout>

try this .. jsut change TextView xml code. if you change android:layout_width="wrap_content" to android:layout_width="match_parent" then it will be horizontally center..

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="Patient List"
    android:id="@+id/title"
    android:gravity="center"/>

</RelativeLayout>

if you change android:layout_height="wrap_content" to match_parent then your textview also will be vertically center ...
