            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="#3EC3D6"

                        android:layout_height="wrap_content"
                        android:ellipsize="marquee"
                        android:gravity="center"
                        android:layout_gravity="center"
                        android:maxLines="1"
                        android:text="Tile"
                        android:textColor="@android:color/black" />


                    <ImageView
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:src="@drawable/chat_new_icon"
                        android:layout_gravity="right"
                        />

                </LinearLayout>

                android:layout_height="?attr/actionBarSize"
                android:background="#3EC3D6"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/AppTheme.NoActionBar.PopupOverlay">

                <RelativeLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="horizontal">

                    <TextView

Just update your code...edited your relative layout implementation

<RelativeLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="horizontal">

                    <TextView
                        android:id="@+id/headerTxt"
                        style="@style/Base.TextAppearance.AppCompat.Medium"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:ellipsize="marquee"
                        android:layout_centerInParent="true"
                        android:maxLines="1"
                        android:text="Tile"
                        android:textColor="@android:color/black" />


                    <ImageView
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:src="@drawable/chat_new_icon"
                        android:layout_toRightOf="@+id/headerTxt"
                         android:layout_centerVertical="true"
                        />

                </RelativeLayout>

@MikeM. suggestion has worked for me. For more detail on the issue please refer this link click here

What i have done to get rid off from the problem is that I have removed the LinearLayout inside the Toolbar and set the gravity of the view with help of android:layout_gravity, Please refer the below solution for it

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="#3EC3D6"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/AppTheme.NoActionBar.PopupOverlay">

                <TextView
                    android:id="@+id/headerTxt"
                    style="@style/Base.TextAppearance.AppCompat.Medium"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="center"
                    android:ellipsize="marquee"
                    android:maxLines="1"
                    android:text="Tile"
                    android:textColor="@android:color/black" />

                <ImageView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="right"
                    android:layout_marginRight="10dp"
                    android:src="@drawable/chat_new_icon" />


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