我正在尝试将ImageButton置于NetworkImageView上方,其中两者都在内部相对布局中,而CardView内部的相对布局和按钮不会显示在其上方;这是我的代码:

<android.support.design.card.MaterialCardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:cardBackgroundColor="@android:color/transparent"
app:cardElevation="0dp"
app:cardPreventCornerOverlap="true"
app:contentPaddingTop="@dimen/shr_staggered_product_grid_margin_top_first">

    <!-- Product card layout used in MDC-103 and onward -->
    <RelativeLayout
        android:id="@+id/content_layout"
        android:layout_width="@dimen/shr_staggered_product_grid_card_width_landscape"
        android:layout_height="wrap_content"
        android:layout_margin="16dp"
        android:layout_marginTop="16dp"
        android:orientation="vertical"
        app:layout_constraintTop_toTopOf="parent">


        <com.android.volley.toolbox.NetworkImageView
            android:id="@+id/product_image"
            android:layout_width="match_parent"
            android:layout_height="@dimen/shr_staggered_product_grid_card_height_landscape"
            android:background="?attr/colorPrimaryDark"
            android:elevation="0dp"
            android:scaleType="centerCrop" />

        <ImageButton
            android:id="@+id/add_to_chart_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="304dp"
            android:layout_marginTop="2dp"
            android:background="?attr/colorPrimaryDark"
            android:elevation="8dp"
            app:srcCompat="@drawable/shr_add_to_chart"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintTop_toTopOf="parent" />
</RelativeLayout>
</android.support.design.card.MaterialCardView>

我不明白为什么没有出现任何人可以帮助我。
