微调器被衬垫布局的背景隐藏

Question

我想在一个矩形中显示微调器，周围有脏的填充颜色。我的代码如下

          <LinearLayout
    android:id="@+id/linearLayout"
    android:layout_width="0dp"
    android:layout_height="113dp"
    android:layout_margin="10dp"
    android:layout_marginStart="9dp"
    android:layout_marginLeft="9dp"
    android:layout_marginEnd="9dp"
    android:layout_marginRight="9dp"
    android:background="@drawable/rectangle_shape"
    android:orientation="vertical"
    android:padding="10dp"
    android:visibility="visible"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">
    <Spinner
        android:id="@+id/spinmain"
        android:layout_width="352dp"
        android:layout_height="25dp"
        android:layout_marginStart="16dp"
        android:layout_marginLeft="16dp"
        android:layout_marginTop="60dp"
        android:layout_marginBottom="416dp"
        android:dropDownVerticalOffset="35dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="@+id/view7" />
</LinearLayout>

和rectangle_shape.xml

 <?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/re/android">
 <item>
    <shape android:shape="rectangle">
        <solid android:color="#FF0000" />
    </shape>
</item>
<item android:left="5dp" android:right="5dp"  android:top="5dp" >
    <shape android:shape="rectangle">
        <solid android:color="#000000" />
    </shape>
   </item>
   </layer-list>

但问题是微调器被矩形线性布局隐藏我怎样才能把微调器带到它前面。请建议

尝试将android:layout_height="113dp"从 113 更改为 match_parent
