Here,
You need two things circleimageview + background(blue image).

If you want best result for all devices then set-background with blue image and according to device give border_width to Cirlceimageview so you can get imageview like above.

<pre><code>&lt;RelativeLayout
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"&gt;
 &lt;de.hdodenhof.circleimageview.CircleImageView
 xmlns:app="http://schemas.android.com/apk/res-auto"
 android:id="@+id/profile_image"
 android:layout_width="wrap_content"
 android:layout_centerInParent="true"
 android:layout_height="wrap_content"
 android:src="@mipmap/profile" //user profile
 android:background="@mipmap/njvkf" //Blue image
 app:civ_border_width="4dp"
 app:civ_border_color="#31A1DA"/&gt;
 &lt;/RelativeLayout&gt;
</code></pre>

Add Cirlceimageview class <a href="http://i.stack.imgur.com/PB3SJ.png" rel="nofollow">you can see result of above code snippet</a>

<pre><code>dependencies {
 compile 'de.hdodenhof:circleimageview:2.1.0'
}
</code></pre>

blocks|key|1182281|text|您可以使用：app:civ_fill_color|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1182282|<de.hdodenhof.circleimageview.CircleImageView

You can use: <code>app:civ_fill_color</code> 

<pre><code>&lt;de.hdodenhof.circleimageview.CircleImageView
 android:id="@+id/v_image"
 android:layout_width="50dp"
 android:layout_height="50dp"
 android:layout_marginEnd="8dp"
 app:civ_fill_color="@color/"
 android:src="@drawable/car" /&gt;
</code></pre>

这很奇怪，但我非常困惑，因为一个.I需要下载用户资料图片，如下图所示。我有png的外部背景。但我很困惑如何才能做到这一点。如果有人知道更好的和优化的解决方案，请在这里更正。我需要的是，下载的图像将覆盖内白色部分只。
