title: How to make only the child of a cardview clickable, and not the whole cardview itself?
body: <p>Here's the layout of the cardview in context:</p>
  
  <pre><code>&lt;android.support.v7.widget.CardView
          android:id="@+id/card"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:layout_marginLeft="1dp"
          android:layout_marginRight="1dp"
          android:layout_marginTop="-25dp"
          android:clickable="true"
          app:cardUseCompatPadding="true"
          android:foreground="?android:attr/selectableItemBackground"
          app:cardBackgroundColor="@color/md_white_1000"
          card_view:cardCornerRadius="4dp"
          card_view:cardElevation="10dp"&gt;
  
          &lt;RelativeLayout
              android:layout_width="match_parent"
              android:layout_height="match_parent"&gt;
  
              &lt;TextView
                  android:id="@+id/title"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content"
                  android:layout_marginLeft="10dp"
                  android:layout_centerVertical="true"
                  android:layout_marginTop="10dp"
                  android:layout_marginBottom="10dp"
                  android:layout_alignParentLeft="true"
                  android:layout_toLeftOf="@+id/icon"
                  android:ellipsize="marquee"
                  android:marqueeRepeatLimit="marquee_forever"
                  android:maxLines="4"
                  android:textColor="@color/md_teal_900"
                  android:textSize="15sp"
                  android:textStyle="bold" /&gt;
  
              &lt;ImageView
                  android:layout_width="wrap_content"
                  android:layout_marginTop="10dp"
                  android:layout_marginBottom="10dp"
                  android:layout_height="wrap_content"
                  android:focusable="true"
                  android:layout_alignParentRight="true"
                  android:layout_centerVertical="true"
                  android:layout_marginRight="5dp"
                  android:clickable="true"
                  android:id="@+id/icon"
                  android:src="@mipmap/ic_download" /&gt;
  
  
          &lt;/RelativeLayout&gt;
      &lt;/android.support.v7.widget.CardView&gt;
  </code></pre>
  
  <p>I want only the icon (imageview) to be clickable. This cardview is part of a recyclerview, and I can only make the whole card responsive to click, whereas I want only the imageview to be clickable.</p>
