Android中简单的Button设计

有时候在Android中系统给的Button不好看，比较呆板，就会自己来设计一种Button，下面提供一种在drawable中自定义的xml文件来作为Button的背                                   

c,xml                                                                                                                                                                                                                                                                                                          

<strong><span style="color:#009900;BACKGROUND-COLOR: #ffffff"><?xml version="1.0" encoding="utf-8"?>
<!-- 个人理解selector为选择器，且必须要有item做子标签 -->
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- state_pressed此属性设置为true表示点了按钮之后的背景 -->
<item  android:state_pressed="true">
<shape>
<!-- 圆角 -->
<corners
android:radius="10dp"/>
<!-- 按钮的颜色 -->
<solid
android:color="#00FF00"/>
</shape>
</item>
<!-- 默认背景 -->
<item >
<shape>
<corners
android:radius="10dp"/>
<solid
android:color="#0000FF"/>
</shape>

</item>

</selector></span></strong>

 main.xml                                                                                                                                                                                                                                                                                                   

<strong><span style="color:#009900;BACKGROUND-COLOR: #ffffff"><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="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginTop="148dp"
android:background="@drawable/c"
android:text="Button" />

</RelativeLayout>
</span></strong>

当点击按钮的时候就可以看到效果，点击时按钮会变成绿色，松开时又变回蓝色
