Corners ImageView fit inside CardView does not have radius like CardView's corners in Android
<p>I am developing an Android App. In my app I am using <code>CardView</code> and <code>ImageView</code> together. But I am having a problem in designing <code>ImageView</code> inside <code>CardView</code>. The problem is with corner radius radius of <code>ImageView</code>. </p>

<p>I have XML layout for adapter item like this.</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_marginTop="5dp"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    card_view:cardCornerRadius="5dp"
    android:layout_width="match_parent"
    android:id="@+id/di_card_container"
    android:layout_height="wrap_content"&gt;

    &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"&gt;

        &lt;ImageView
            android:id="@+id/di_iv_image"
            android:scaleType="centerCrop"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" /&gt;

        &lt;RelativeLayout
            android:padding="10dp"
            android:layout_below="@id/di_iv_image"
            android:layout_alignParentLeft="true"
            android:layout_alignParentBottom="true"
            android:id="@+id/di_name_container"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"&gt;
            &lt;TextView
                android:textSize="15dp"
                android:textColor="@color/textColorPrimary"
                android:id="@+id/di_tv_name"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" /&gt;
        &lt;/RelativeLayout&gt;
    &lt;/RelativeLayout&gt;
&lt;/android.support.v7.widget.CardView&gt;
</code></pre>

<p>As you can see I set, corner radius of <code>CardView</code> to <code>5dp</code> and the <code>ImageView</code> with is fit to the width of its parent <code>CardView</code>. The problem is both top corners of <code>ImageView</code> is not bent like its parent <code>CardView</code>'s corner.</p>

<p>This is the screenshot</p>

<p>Normally corners of child views of <code>CardView</code> automatically bent like its parent corners if it fit to parent <code>CardView</code>. Is that right? So why is my <code>ImageView</code> is not working?</p>
