一、shape 样式：（在drawable新建--》new--》Drawable resource file 并把原父级标签selector改为shape ）

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="#4ec5ff" />
    <padding
        android:bottom="12dp"
        android:left="12dp"
        android:right="12dp"
        android:top="12dp" />
    <stroke
        android:width="1dp"
        android:color="#ffffff"
        android:dashGap="270dp" />
    <size
        android:width="100dp"
        android:height="100dp" />
</shape>
二、style 样式：
<style name="oval">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:textSize">15sp</item>
    <item name="android:textColor">#ffffff</item>
    <item name="android:background">@drawable/buttonovalstyle</item>
</style>

三、Button控件调用style样式：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.ly.blogtest.MainActivity">
<Button
    style="@style/oval"
    android:text="@string/btn1"
    android:id="@+id/btnOval"
    />
</RelativeLayout>

  • rectangle: 矩形，默认的形状，可以画出直角矩形、圆角矩形、弧形等
  • oval: 椭圆形，用得比较多的是画正圆
  • line: 线形，可以画实线和虚线
  • ring: 环形，可以画环形进度条

  • solid: 设置形状填充的颜色，只有android:color一个属性
    • android:color 填充的颜色
  • padding: 设置内容与形状边界的内间距，可分别设置左右上下的距离
    • android:left 左内间距
    • android:right 右内间距
    • android:top 上内间距
    • android:bottom 下内间距
  • gradient: 设置形状的渐变颜色，可以是线性渐变、辐射渐变、扫描性渐变
    • android:type 渐变的类型
      • linear 线性渐变，默认的渐变类型
      • radial 放射渐变，设置该项时，android:gradientRadius也必须设置
      • sweep 扫描性渐变
    • android:startColor 渐变开始的颜色
    • android:endColor 渐变结束的颜色
    • android:centerColor 渐变中间的颜色
    • android:angle 渐变的角度，线性渐变时才有效，必须是45的倍数，0表示从左到右，90表示从下到上
    • android:centerX 渐变中心的相对X坐标，放射渐变时才有效，在0.0到1.0之间，默认为0.5，表示在正中间
    • android:centerY 渐变中心的相对X坐标，放射渐变时才有效，在0.0到1.0之间，默认为0.5，表示在正中间
    • android:gradientRadius 渐变的半径，只有渐变类型为radial时才使用
    • android:useLevel 如果为true，则可在LevelListDrawable中使用
  • corners: 设置圆角，只适用于rectangle类型，可分别设置四个角不同半径的圆角，当设置的圆角半径很大时，比如200dp，就可变成弧形边了
    • android:radius 圆角半径，会被下面每个特定的圆角属性重写
    • android:topLeftRadius 左上角的半径
    • android:topRightRadius 右上角的半径
    • android:bottomLeftRadius 左下角的半径
    • android:bottomRightRadius 右下角的半径
  • stroke: 设置描边，可描成实线或虚线。
    • android:color 描边的颜色
    • android:width 描边的宽度
    • android:dashWidth 设置虚线时的横线长度
    • android:dashGap 设置虚线时的横线之间的距离
