android圆角矩形的实现，android圆角矩形,在res/drawabl

在res/drawable目录下穿件shape的xml来实现圆角矩形效果。代码如下：

    <?xml version="1.0" encoding="utf-8"?>      <shape xmlns:android="http://schemas.android.com/apk/res/android"          android:shape="rectangle" >          <corners              android:bottomLeftRadius="8dp"              android:bottomRightRadius="8dp"              android:topLeftRadius="8dp"              android:topRightRadius="8dp" />          <gradient              android:angle="45"              android:centerColor="#CCFFDD"              android:endColor="#CCCCCC"              android:startColor="#CCCCCC" />          <padding              android:bottom="7dp"              android:left="7dp"              android:right="7dp"              android:top="7dp" />      </shape>  ```布局文件：```xml    <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=".MainActivity" >          <Button              android:id="@+id/button1"              android:layout_width="140dp"              android:layout_height="60dp"              android:layout_alignParentTop="true"              android:layout_centerHorizontal="true"              android:background="@drawable/button"              android:text="设置Shape的形状" />          <LinearLayout              android:layout_width="200dp"              android:layout_height="100dp"              android:layout_alignParentLeft="true"              android:layout_alignParentRight="true"              android:layout_below="@+id/button1"              android:layout_marginTop="71dp"             <span style="color:#ff0000;"> android:background="@drawable/button"</span>              android:orientation="vertical" >          </LinearLayout>      </RelativeLayout>
