Android设置虚线、圆角、渐变

有图又真相,先上图再说。

点击效果:

设置虚线:

  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>

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:

  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>

设置渐变填充和四个圆角半径:

  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>

设置渐变点击效果:

  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>

 

  1. <?xml version=“1.0” encoding=“UTF-8”?>
  2. <inset xmlns:android=“http://schemas.android.com/apk/res/android”
  3.     android:insetLeft=“1.0px”
  4.     android:insetRight=“1.0px” >
  5.     <selector>
  6.         <item android:state_pressed=“true”>
  7.             <shape>
  8.                 <gradient
  9.                     android:angle=“270.0”
  10.                     android:endColor=“@color/base_end_color_pressed”
  11.                     android:startColor=“@color/base_start_color_pressed” />
  12.                 <corners
  13.                     android:bottomLeftRadius=“0.0dip”
  14.                     android:bottomRightRadius=“0.0dip”
  15.                     android:radius=“2.0dip”
  16.                     android:topLeftRadius=“10.0dip”
  17.                     android:topRightRadius=“10.0dip” />
  18.                 <stroke
  19.                     android:width=“1dp”
  20.                     android:color=“#eededede” />
  21.             </shape>
  22.         </item>
  23.         <item>
  24.             <shape>
  25.                 <gradient
  26.                     android:angle=“270.0”
  27.                     android:endColor=“@color/base_end_color_default”
  28.                     android:startColor=“@color/base_start_color_default” />
  29.                 <corners
  30.                     android:bottomLeftRadius=“0.0dip”
  31.                     android:bottomRightRadius=“0.0dip”
  32.                     android:radius=“2.0dip”
  33.                     android:topLeftRadius=“11.0dip”
  34.                     android:topRightRadius=“11.0dip” />
  35.                 <stroke
  36.                     android:width=“1dp”
  37.                     android:color=“#eededede” />
  38.             </shape>
  39.         </item>
  40.     </selector>
  41. </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:

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

xml中可以添加:

  1. android:layerType=“software”

谢谢大家的参与!
