<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android" >        <!-- 圆角 -->    <corners        android:radius="9dp"        android:topLeftRadius="2dp"        android:topRightRadius="2dp"        android:bottomLeftRadius="2dp"        android:bottomRightRadius="2dp"/><!-- 设置圆角半径 -->        <!-- 渐变 -->    <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"/>        <!-- 间隔 -->    <padding        android:left="2dp"        android:top="2dp"        android:right="2dp"        android:bottom="2dp"/><!-- 各方向的间隔 -->        <!-- 大小 -->    <size        android:width="50dp"        android:height="50dp"/><!-- 宽度和高度 -->        <!-- 填充 -->    <solid        android:color="@android:color/white"/><!-- 填充的颜色 -->        <!-- 描边 -->    <stroke        android:width="2dp"        android:color="@android:color/black"        android:dashWidth="1dp"        android:dashGap="2dp"/>    </shape>

单独画个单行线

//横向的虚线<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android"    android:shape="line">    <stroke android:color="#fff"        android:dashGap="2dp"        android:dashWidth="2dp"        android:width="@dimen/view_size_small"/>    <size android:height="3dp"/></shape>//竖向的虚线<?xml version="1.0" encoding="utf-8"?><rotate xmlns:android="http://schemas.android.com/apk/res/android"    android:fromDegrees="90" android:toDegrees="90">    <shape android:shape="line">        <stroke            android:width="1dp"            android:color="#fff"            android:dashGap="2dp"            android:dashWidth="1dp" />        <size android:width="0.5dp" />    </shape></rotate>
