How to define a circle shape in an android xml drawable file?
I have some problems finding the documentation of the definitions of shapes in XML for Android. I would like to define a simple circle filled with a solid color in an XML File to include it into my layout files.
Sadly the Documentation on android.com does not cover the XML attributes of the Shape classes. I think I should use an ArcShape to draw a circle but there is no explanation on how to set the size, the color, or the angle needed to make a circle out of an Arc.
这在Android中是一个简单的圈子。
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid
android:color="#666666"/>
<size
android:width="120dp"
android:height="120dp"/>
</shape>
Set this as your view background
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<stroke
android:width="1dp"
android:color="#78d9ff"/>
</shape>
For solid circle use:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid
android:color="#48b3ff"/>
</shape>
Solid with stroke:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#199fff"/>
<stroke
android:width="2dp"
android:color="#444444"/>
</shape>
Note : To make the oval shapes appear as circle, in these examples, either your view that your are using these shapes as its background should be a square or you have to set the height and width properties of the shape tag to an equal value.
