Android: center and right alignment inside LinearLayout

I have two Linear Layouts one inside the other. In the second one I have a

Switch
button, a
TextView
and a
FloatingActionButton
. I want to put these 3 in the same line and I want to centralize the Switch and the
TextView
and I want to align the
FloatingActionButton
on the right side of the screen. I tried to use
marginLeft
to force them to go to the position I want but I believe this is not the correct way. Can somebody please help me?

Here's my code (right now the 3 components are already in the same line):

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

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="80dp"
android:orientation="horizontal"
android:weightSum="1" >

<Switch
android:id="@+id/mySwitch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_marginLeft="140dp"
android:layout_marginTop="20dp"
android:theme="@style/SCBSwitch"
/>

<TextView
android:id="@+id/OpenClose"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:layout_marginLeft="10dp"
android:text="Open"
android:textSize="20dp"/>

<android.support.design.widget.FloatingActionButton
android:id="@+id/action_find_location"
android:layout_width="277dp"
android:layout_height="40dp"
android:layout_marginTop="10dp"
android:layout_marginLeft="75dp"
android:layout_marginRight="10dp"
android:src="@drawable/calendar_today"
fab:backgroundTint="@color/theme_color"
fab:borderWidth="0dp"
fab:elevation="9dp"
fab:rippleColor="@color/toolbar_title_color"
fab:fabSize="mini"/>

</LinearLayout>
</LinearLayout>

Just took your code and made some changes. Please check if it works fine

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

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="80dp"
    android:orientation="horizontal"
    android:weightSum="3">

    <Switch
        android:id="@+id/mySwitch"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:theme="@style/SCBSwitch"
        android:layout_gravity="start"
        android:gravity="center"
        android:layout_weight="1"/>

    <TextView
        android:id="@+id/OpenClose"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:text="Open"
        android:textSize="20dp"
        android:layout_gravity="center_horizontal"
        android:gravity="center"
        android:layout_weight="1"/>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/action_find_location"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:src="@drawable/calendar_today"
        fab:backgroundTint="@color/theme_color"
        fab:borderWidth="0dp"
        fab:elevation="9dp"
        fab:rippleColor="@color/toolbar_title_color"
        fab:fabSize="mini"
        android:layout_gravity="end"
        android:gravity="center"
        android:layout_weight="1"/>
