Android设置虚线、圆角、渐变

from:http://blog.youkuaiyun.com/lan410812571/article/details/9946991

有图又真相，先上图再说。

点击效果：

设置虚线：

[html] view plain copy print ?

1. <?xml version="1.0" encoding="utf-8"?>  
2. <shape xmlns:android="http://schemas.android.com/apk/res/android"  
3.     android:shape="line" >  
4.     <stroke  
5.         android:dashGap="3dp"  
6.         android:dashWidth="6dp"  
7.         android:width="1dp"  
8.         android:color="#63a219" />  
9.     <!-- 虚线的高度 -->  
10.     <size android:height="1dp" />  
11. </shape>  

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="line" >
    <stroke
        android:dashGap="3dp"
        android:dashWidth="6dp"
        android:width="1dp"
        android:color="#63a219" />
	<!-- 虚线的高度 -->
    <size android:height="1dp" />
</shape>

其中，破折线的宽度为dashWith，破折线之间的空隙的宽度为dashGap，当dashGap=0dp时，为实线

设置圆角:

[html] view plain copy print ?

1. <?xml version="1.0" encoding="utf-8"?>  
2. <shape xmlns:android="http://schemas.android.com/apk/res/android"   
3.     android:shape="rectangle">  
4.     <!-- 填充颜色 -->  
5.     <solid android:color="#FFFFFF"></solid>  
6.     <!-- 线的宽度，颜色灰色 -->  
7.     <stroke android:width="1dp" android:color="#63a219"></stroke>          
8.     <!-- 矩形的圆角半径 -->  
9.     <corners android:radius="10dp" />         
10. </shape>  

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">
    <!-- 填充颜色 -->
    <solid android:color="#FFFFFF"></solid>
    <!-- 线的宽度，颜色灰色 -->
    <stroke android:width="1dp" android:color="#63a219"></stroke>        
    <!-- 矩形的圆角半径 -->
    <corners android:radius="10dp" />       
</shape>

设置渐变填充和四个圆角半径：

[html] view plain copy print ?

1. <shape xmlns:android="http://schemas.android.com/apk/res/android"   
2.     android:shape="rectangle">  
3.     <!--分別對應上面左圆角的半径，上面右圆角的半径，下面左圆角的半径，下面右圆角的半径-->  
4.     <corners    
5.           android:topLeftRadius="0dp"  
6.           android:topRightRadius="7dp"  
7.           android:bottomLeftRadius="0dp"  
8.           android:bottomRightRadius="7dp"/>  
9.     <!--設置漸變-->  
10.     <gradient android:startColor="#9cff00"   
11.           android:endColor="#197600"  
12.           android:angle="270"/>  
13.     <stroke     
14.         android:width="1dp"   
15.         android:color="#63a219" />   
16. </shape>  

<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">
    <!--分別對應上面左圆角的半径，上面右圆角的半径，下面左圆角的半径，下面右圆角的半径-->
    <corners  
          android:topLeftRadius="0dp"
          android:topRightRadius="7dp"
          android:bottomLeftRadius="0dp"
          android:bottomRightRadius="7dp"/>
    <!--設置漸變-->
    <gradient android:startColor="#9cff00" 
          android:endColor="#197600"
          android:angle="270"/>
    <stroke   
        android:width="1dp" 
        android:color="#63a219" /> 
</shape>

设置渐变点击效果：

[html] view plain copy print ?

1. <style name="list_item_top">  
2.     <item name="android:clickable">true</item>  
3.     <item name="android:focusable">true</item>  
4.     <item name="android:paddingTop">10dip</item>  
5.     <item name="android:paddingBottom">10dip</item>  
6.     <item name="android:paddingLeft">10dip</item>  
7.         <item name="android:paddingRight">10dip</item>  
8.         <item name="android:gravity">center_vertical</item>  
9.         <item name="android:background">@drawable/background_view_rounded_top</item>  
10. </style>  

<style name="list_item_top">
	<item name="android:clickable">true</item>
	<item name="android:focusable">true</item>
	<item name="android:paddingTop">10dip</item>
	<item name="android:paddingBottom">10dip</item>
	<item name="android:paddingLeft">10dip</item>
    	<item name="android:paddingRight">10dip</item>
    	<item name="android:gravity">center_vertical</item>
    	<item name="android:background">@drawable/background_view_rounded_top</item>
</style>

        </item>
    </selector>

</inset>

重新补充：好久没有关注自己的博客，没有注意到各位的评论，关于4.0以上设备虚线会变实线的问题，下面几位仁兄已经给出了答案，

代码中可以添加：

[java] view plain copy print ?

1. line.setLayerType(View.LAYER_TYPE_SOFTWARE, null);  

line.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

xml中可以添加：

[html] view plain copy print ?

1. android:layerType="software"  

android:layerType="software"

谢谢大家的参与！
