The filename is used as the resource ID.

COMPILED RESOURCE DATATYPE:

Resource pointer to a GradientDrawable.

RESOURCE REFERENCE:

In Java: R.drawable.filename
In XML: @[package:]drawable/filename

ELEMENTS:

<shape>

The shape drawable. This must be the root element.

attributes:

xmlns:android

String. Required.Defines the XML namespace,which must be "http://schemas.android.com/apk/res/android".

android:shape

Keyword. Defines the type of shape. Valid values are:

Value	Desciption
"rectangle"	A rectangle that fills the containing View. This is the default shape.
"oval"	An oval shape that fits the dimensions of the containing View.
"line"	A horizontal line that spans the width of the containing View. This shape requires the<stroke>element to define the width of the line.
"ring"	A ring shape.

The following attributes are used only whenandroid:shape="ring":

android:innerRadius

Dimension. The radius for the inner part of the ring (the hole in the middle),as a dimension value or dimension resource.

android:innerRadiusRatio

Float. The radius for the inner part of the ring,expressed as a ratio of the ring's width. For instance,if android:innerRadiusRatio="5",then the inner radius equals the ring's width divided by 5. This value is overridden by android:innerRadius. Default value is 9.

android:thickness

Dimension. The thickness of the ring,229); text-decoration:none" rel="nofollow">dimension resource.

android:thicknessRatio

Float. The thickness of the ring,if android:thicknessRatio="2",then the thickness equals the ring's width divided by 2. This value is overridden by android:innerRadius. Default value is 3.

android:useLevel

Boolean. "true" if this is used as a LevelListDrawable. This should normally be "false" or your shape may not appear.

<corners>

Creates rounded corners for the shape. Applies only when the shape is a rectangle.

attributes:

android:radius

Dimension. The radius for all corners,229); text-decoration:none" rel="nofollow">dimension resource. This is overridden for each corner by the following attributes.

android:topLeftRadius

Dimension. The radius for the top-left corner,229); text-decoration:none" rel="nofollow">dimension resource.

android:topRightRadius

Dimension. The radius for the top-right corner,229); text-decoration:none" rel="nofollow">dimension resource.

android:bottomLeftRadius

Dimension. The radius for the bottom-left corner,229); text-decoration:none" rel="nofollow">dimension resource.

android:bottomRightRadius

Dimension. The radius for the bottom-right corner,229); text-decoration:none" rel="nofollow">dimension resource.

Note:Every corner must (initially) be provided a corner radius greater than 1,or else no corners are rounded. If you want specific corners tonotbe rounded,a work-around is to useandroid:radiusto set a default corner radius greater than 1,but then override each and every corner with the values you really want,providing zero ("0dp") where you don't want rounded corners.

<gradient>

Specifies a gradient color for the shape.

attributes:

android:angle

Integer. The angle for the gradient,in degrees. 0 is left to right,90 is bottom to top. It must be a multiple of 45. Default is 0.

android:centerX

Float. The relative X-position for the center of the gradient (0 - 1.0).

android:centerY

Float. The relative Y-position for the center of the gradient (0 - 1.0).

android:centerColor

Color. Optional color that comes between the start and end colors,as a hexadecimal value or color resource.

android:endColor

Color. The ending color,229); text-decoration:none" rel="nofollow">color resource.

android:gradientRadius

Float. The radius for the gradient. Only applied when android:type="radial".

android:startColor

Color. The starting color,229); text-decoration:none" rel="nofollow">color resource.

android:type

Keyword. The type of gradient pattern to apply. Valid values are: Description

"linear"	A linear gradient. This is the default.
"radial"	A radial gradient. The start color is the center color.
"sweep"	A sweeping line gradient.

android:useLevel

Boolean. "true" if this is used as a LevelListDrawable.

<padding>

Padding to apply to the containing View element (this pads the position of the View content,not the shape).

attributes:

android:left

Dimension. Left padding,229); text-decoration:none" rel="nofollow">dimension resource.

android:top

Dimension. Top padding,229); text-decoration:none" rel="nofollow">dimension resource.

android:right

Dimension. Right padding,229); text-decoration:none" rel="nofollow">dimension resource.

android:bottom

Dimension. Bottom padding,229); text-decoration:none" rel="nofollow">dimension resource.

<size>

The size of the shape.

attributes:

android:height

Dimension. The height of the shape,229); text-decoration:none" rel="nofollow">dimension resource.

android:width

Dimension. The width of the shape,255)"> Note:The shape scales to the size of the container View proportionate to the dimensions defined here,by default. When you use the shape in anImageView,you can restrict scaling by setting theandroid:scaleTypeto"center".

<solid>

A solid color to fill the shape.

attributes:

android:color

Color. The color to apply to the shape,229); text-decoration:none" rel="nofollow">color resource.

<stroke>

A stroke line for the shape.

attributes:

android:width

Dimension. The thickness of the line,229); text-decoration:none" rel="nofollow">dimension resource.

android:color

Color. The color of the line,229); text-decoration:none" rel="nofollow">color resource.

android:dashGap

Dimension. The distance between line dashes,229); text-decoration:none" rel="nofollow">dimension resource. Only valid if android:dashWidthis set.

android:dashWidth

Dimension. The size of each dash line,229); text-decoration:none" rel="nofollow">dimension resource. Only valid if android:dashGapis set.

EXAMPLE:

XML file saved at res/drawable/gradient_box.xml:

<shape "rectangle"<gradient"#FFFF0000""#80FF00FF""45"<padding"7dp"<corners"8dp"</shape>

This layout XML applies the shape drawable to a View:

<TextViewandroid:background"@drawable/gradient_box"android:layout_height"wrap_content"android:layout_width/>

This application code gets the shape drawable and applies it to a View:

Resources res = ;
Drawable shape  res.(Rdrawablegradient_box);

TextView tv (TextView)findViewByIDidtextview
tvsetBackgroundshape);getResources()getDrawable
