java - 如何从底部设计圆形 View ？

Question

我正在尝试设计一个从底部看是圆形的 View ，请看图片

I have try different way to design, Like XML, Programatically but I am not able to get any success. I use XML code it's doing circle from bottom but when I use Any image or Banner slider as show in figure then it's hold whole view.

现在我正在使用这段代码 XML

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:background="@drawable/bottom_radius"
    android:orientation="vertical">

    <ss.com.bannerslider.views.BannerSlider
        android:id="@+id/bannerSlider"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>

和bottom_radius.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="oval">
        <solid android:color="@color/colorPrimaryDark" />
    </shape>
</item>
<item
    android:bottom="4dp"
    android:left="0dp"
    android:right="0dp"
    android:top="0dp">
    <shape android:shape="oval">
        <solid android:color="@android:color/white" />
    </shape>
</item>

输出就像 XML 中那样

The XML output is looks good as I expected, but when I run the program and see the out put on the mobile or simulator then output is looks like

Please provide me solution so that I can design what I want to design. I will be very thank full to you.
