Half circle shape not work

Question

I try to create half circle background, in development IDE preview it works, but when I launch in emulator it doesn't work.

Here is my shape code :

<?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android">     <item android:height="50dp">         <shape>             <solid android:color="@color/colorAccentDark" />         </shape>     </item>     <item android:top="-500dp" android:bottom="0dp" android:left="-100dp" android:right="-100dp">         <shape>             <corners android:radius="500dp" />             <solid android:color="@color/colorAccentDark" />         </shape>     </item> </layer-list> 

And here is my layout code :

<?xml version="1.0" encoding="utf-8"?> <LinearLayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical">      <RelativeLayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:background="@drawable/background_profile"         android:layout_weight="1">          <de.hdodenhof.circleimageview.CircleImageView             android:id="@+id/profile_avatar"             android:layout_width="100dp"             android:layout_height="100dp"             android:src="@drawable/ic_default_avatar"             android:layout_centerHorizontal="true"             android:layout_marginTop="50dp"/>          <TextView             android:id="@+id/profile_name"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_centerHorizontal="true"             android:layout_below="@id/profile_avatar"             android:layout_marginTop="20dp"             android:textColor="@color/neutralWhite"             android:textStyle="bold"             android:textSize="18sp"             android:text="Avatar Ang"/>      </RelativeLayout>      <RelativeLayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_weight="4.04">          <TextView             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="Hello Android!"/>      </RelativeLayout>  </LinearLayout> 

Maybe any other tweak to handle that? Thank you

Answer 1

you can try this :

<?xml version="1.0" encoding="utf-8"?> <shape     xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="rectangle">     <solid android:color="#900021df"/>     <size         android:width="10dp"         android:height="5dp"/>     <corners         android:bottomLeftRadius="20dp"         android:bottomRightRadius="20dp"/> </shape> 

it gives this shape:
