android 半圆按钮

Question

我有两个按钮，我想将它们的形状更改为半圆形。然后将它们并排放置成一个完整的圆圈。已附加图像以显示我想要的按钮外观。任何帮助将不胜感激。谢谢。

您必须创建一个可绘制的 xml 文件。

left_corner.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
 <corners android:radius="1dp"
  android:bottomRightRadius="0dp" android:bottomLeftRadius="25dp" 
  android:topLeftRadius="25dp" android:topRightRadius="0dp"/>  // here you have to put dimen as per reqiurement

    <solid android:color="@color/green" />
</shape>

right_corner.xml

 <?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android">
     <corners android:radius="1dp"
      android:bottomRightRadius="25dp" android:bottomLeftRadius="0dp" 
      android:topLeftRadius="0dp" android:topRightRadius="25dp"/>  // here you have to put dimen as per reqiurement

        <solid android:color="@color/green" />
    </shape>

布局.xml

<Linearlayout
             android:orientation="horizontal"
             android:layout_width="match_parent"
             android:layout_height="match_parent">
     <Button android:layout_width="@dimen/_150sdp"
             android:layout_height="@dimen/_150sdp"
             android:background="@draable/left_corner"/>

     <Button android:layout_width="@dimen/_150sdp"
             android:layout_height="@dimen/_150sdp"
             android:background="@draable/right_corner"/>
</Linearlayout>

这对我来说是工作..
