<p>I used the below code 
activity_main.xml</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:layout_marginBottom="5dp"
    android:background="@drawable/my_custom_drawable"
    xmlns:android="http://schemas.android.com/apk/res/android"&gt;
    &lt;ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/dead"
        android:scaleType="fitXY"
        android:id="@+id/place_image"
        /&gt;
    &lt;RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_alignParentBottom="true"
        android:background="#AA000000"&gt;
        &lt;TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Medeu"
            android:id="@+id/place_id"
            android:layout_marginLeft="20dp"
            android:layout_marginTop="2dp"
            android:textSize="18sp"
            android:textColor="#ffffff"/&gt;
        &lt;TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Almaty region"
            android:textColor="#ffffff"
            android:layout_marginLeft="20dp"
            android:layout_below="@+id/place_id"
            android:textSize="12sp"
            android:id="@+id/place_id_sub"

            /&gt;
    &lt;/RelativeLayout&gt;
&lt;/RelativeLayout&gt;
</code></pre>

<p>and my_custom_drawable.xml</p>



<pre><code>&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"&gt;
    &lt;gradient
        android:startColor="#00000000"
        android:endColor="#80000000"
        android:angle="270"
        android:dither="true"
        /&gt;
&lt;/shape&gt;
</code></pre>

<p>I end up getting like this</p>
