Android shape usage

From: http://www.cnblogs.com/cyanfei/archive/2012/07/27/2612023.html

Shape is used to set the shape. It can be used in selector, layout, and so on. There are 6 sub-labels. Each attribute is as follows:

 <?  XML version = "1.0" encoding = "UTF-8"  ?>  <  Shape Xmlns: Android  = "Http://schemas.android.com/apk/res/android"   >          <! --  Rounded corner  -->      <  Corners  Android: radius  = "9dp" Android: topleftradius  = "2dp"  Android: toprightradius  = "2dp"  Android: bottomleftradius  = "2dp"  Android: bottomrightradius  = "2dp"  />  <! -- Set the rounded corner radius  -->          <! --  Gradient  -->      <  Gradient  Android: startcolor  = "@ Android: color/White"  Android: centercolor = "@ Android: color/Black"  Android: endcolor  = "@ Android: color/Black"  Android: uselevel  = "True"  Android: Angle  = "45"  Android: Type  = "RADIAL"  Android: centerx = "0"  Android: centery  = "0"  Android: gradientradius  = "90"  />          <! --  Interval  -->      <  Padding Android: left  = "2dp"  Android: Top  = "2dp"  Android: Right  = "2dp"  Android: Bottom  = "2dp"  />  <! --  Interval in each direction -->          <! --  Size  -->      <  Size  Android: width  = "50dp"  Android: Height  = "50dp"  /> <! --  Width and height  -->          <! --  Fill  -->      <  Solid  Android: Color  = "@ Android: color/White"  /> <! --  Fill color  -->          <! --  Stroke  -->      <  Stroke  Android: width  = "2dp"  Android: Color = "@ Android: color/Black"  Android: dashwidth  = "1dp"  Android: dashgap  = "2dp"  />      </  Shape  > 

Fill:Set fill color

Interval:Set the interval in four directions

Size:SET SIZE

Rounded corner:If five attributes are set at the same time, the radius attribute is invalid.

Android: radius = "20dp" sets the radius of the four corners

Android: topleftradius = "20dp" sets the radius in the upper left corner.

Android: toprightradius = "20dp" sets the radius in the upper right corner.

Android: bottomleftradius = "20dp" sets the radius in the lower right corner.

Android: bottomrightradius = "20dp" sets the radius in the lower left corner.

Stroke:The dashwidth and dashgap attributes. If one of them is set to 0dp, the border is the implemented border.

Android: width =" 20dp "sets the edge width

Android: color =" @ Android: color/Black "set the edge color

Android: dashwidth =" 2dp "set the width of the dotted line

Android: dashgap = "20dp" set the interval width of the dotted line

Gradient:After the fill color is set, there is no gradient effect. The angle value must be a multiple of 45 (including 0) and only valid in type = "linear". Otherwise, an error is returned. Android: uselevel.

Start Point of the angle value
