Example to implement shape of oval with gradient color

shape of oval

To implement shape using "oval", create /res/drawable/myshape.xml to define the shape.
<shape 
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" >
<solid
android:color="#e0e0e0" />
<stroke
android:width="5dip"
android:color="#505050"/>
<gradient
android:startColor="#FFFF0000"
android:endColor="#800000FF"
android:angle="45"/>
</shape>


Apply the shape on layout background, modify /res/layout/activity_main.xml.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:orientation="vertical"
tools:context=".MainActivity" >

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello"
android:textStyle="bold|italic"
android:layout_gravity="center_horizontal"
android:background="#B0B0B0" />
<ImageView

android:layout_height="wrap_content"
android:src="@drawable/ic_launcher"
