Android布局:在两个视图之间放置一个视图

我正在尝试制作一个屏幕,最好只使用XML,如下所示: enter image description here

我跟着this approach,但是使用FrameLayout我只能选择" orange"使用layout_gravity查看,当我尝试在图片中解释时,我不知道布局'高度,因为两者都用layout_weight测量。

我的布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="onit.radiolisten.MainActivity">

    <FrameLayout
        android:id="@+id/layout_container_activity_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <!-- TOP LAYOUT, THE GREEN ONE ON THE IMAGE -->
            <LinearLayout
                android:id="@+id/layout_top_activity_main"
                android:layout_width="match_parent"
                android:layout_height="0dip"
                android:layout_weight="2"
                android:background="@color/colorPrimary"
                android:orientation="vertical"></LinearLayout>

            <!-- BOTTOM LAYOUT, THE BLUE ONE ON THE IMAGE -->
            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:layout_weight="1"
                android:background="#e6e6e6">

            </RelativeLayout>
        </LinearLayout>

        <!-- THIS IS THE IMAGE I WANT TO POSITION -->
        <ImageView
            android:id="@+id/btn_play_radio"
            android:layout_width="120dp"
            android:layout_height="120dp"
            android:layout_gravity="center"
            android:src="@drawable/play_icon" />
    </FrameLayout>

</LinearLayout>

这可以仅用XML完成吗?
