有图又真相，先上图再说。

设置虚线：

[html]
view plaincopyprint?





<?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>

<?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 plaincopyprint?





<?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>

<?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 plaincopyprint?





<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>

<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 plaincopyprint?

</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 plaincopyprint?





line.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

line.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

xml中可以添加：

[html]
view plaincopyprint?





android:layerType="software"

android:layerType="software"

谢谢大家的参与！
