Question

I am trying to draw a custom shape which I can use as a background for my layout. But I am not able to do so. Is it possible to draw a shape as below using xml in android. I am not getting how to cut the semicircle shape from the vertical centres of rectangle.

Answer 1

Use layer-list to make this custom shape drawable .

/res/drawable/custom_shape.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Transparent Rectangle -->
    <item>
        <shape android:shape="rectangle">
            <corners
                android:topLeftRadius="8dp"
                android:topRightRadius="8dp"
                android:bottomLeftRadius="4dp"
                android:bottomRightRadius="4dp" />

            <size
                android:width="300dp"
                android:height="100dp" />
            <solid android:color="#FFFFFF" />
        </shape>
    </item>

    <!-- Left Half-Circle -->
    <item
        android:left="-10dp"
        android:right="290dp"
        android:top="40dp"
        android:bottom="40dp">
        <shape android:shape="oval">
            <solid android:color="#000000" />
        </shape>
    </item>

    <!-- Right Half-Circle -->
    <item
        android:left="290dp"
        android:right="-10dp"
        android:top="40dp"
        android:bottom="40dp">
        <shape android:shape="oval">
            <solid android:color="#000000" />
        </shape>
    </item>

    <!-- Middle Dotted Line -->
    <item
        android:left="10dp"
        android:right="10dp">
        <shape android:shape="line">
            <stroke
                android:width="1dp"
                android:dashWidth="10px"
                android:dashGap="10px"
                android:color="#ff00"/>

        </shape>
    </item>

</layer-list>

USE:

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/custom_shape"/>

OUTPUT:

Hope this will help~

Answer 3

In your case it might be worth to create a resizable bitmap ( 9-Patch drawable). Follow this guide.

Answer 4

It is better to use 9-Patch images. If you can create an image like above you can use https://romannurik.github.io/AndroidAssetStudio/nine-patches.html to create 9-patch image(define expandable area).

Try this xml file in drawable :

<corners android:radius="50dp"/>
