效果图
绿色Button
定义button_green.xml资源文件位于drawable文件夹下,可用作button的background属性
button_green.xml:
1 <?xml version="1.0" encoding="utf-8"?> 2 <selector xmlns:android="http://schemas.android.com/apk/res/android"> 3 <item android:state_pressed="true"> 4 <shape> 5 <!-- 填充 --> 6 <solid android:color="@color/green" /> 7 <!-- 描边 --> 8 <stroke 9 android:width="1dp" 10 android:color="@color/cyan" /> 11 <!-- 圆角 --> 12 <corners android:radius="6dp"/> 13 <padding android:top="10dp" android:bottom="10dp" 14 android:left="20dp" 15 android:right="20dp"/> 16 </shape> 17 </item> 18 <item> 19 <shape> 20 <solid android:color="@android:color/transparent" /> 21 <padding android:top="10dip" android:bottom="10dip" 22 android:left="20dp" 23 android:right="20dp"/> 24 <stroke 25 android:width="1dp" 26 android:color="@color/green" /> 27 28 <corners android:radius="6dp"/> 29 </shape> 30 </item> 31 </selector>

带渐变的橙色Button
定义button_orange.xml资源文件位于drawable文件夹下,代码如下:

1 button_orange.xml: 2 <?xml version="1.0" encoding="utf-8"?> 3 4 <selector xmlns:android="http://schemas.android.com/apk/res/android"> 5 <item android:state_enabled="false"> 6 <shape> 7 <gradient 8 android:startColor="#D0D0D0" 9 android:centerColor="#B0B0B0" 10 android:centerY="0.75" 11 android:endColor="#D0D0D0" 12 android:angle="270" 13 /> 14 <corners android:radius="6dp"/> 15 </shape> 16 </item> 17 18 <item android:state_pressed="true" android:state_enabled="true"> 19 <shape> 20 <gradient 21 android:startColor="#F5AA1C" 22 android:centerColor="#F29600" 23 android:centerY="0.75" 24 android:endColor="#F5AA1C" 25 android:angle="270" 26 /> 27 <stroke android:width="1dp" android:color="#FBB343" /> 28 <corners android:radius="6dp" /> 29 </shape> 30 </item> 31 32 <item android:state_enabled="true"> 33 <shape> 34 <gradient 35 android:startColor="#FBB03B" 36 android:centerColor="#FBB03B" 37 android:centerY="0.75" 38 android:endColor="#FBB03B" 39 android:angle="270" 40 /> 41 42 <stroke android:width="1dp" android:color="#FBB343" /> 43 <padding android:left="20dp" 44 android:right="20dp" 45 android:top="10dp" 46 android:bottom="10dp"/> 47 48 <corners android:radius="6dp" /> 49 </shape> 50 </item> 51 </selector>
自定义Button的使用
为方便使用,定义GreenButton和OrangeButton风格的style,代码如下:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
1 styles.xml: 2 <resources> 3 4 <!-- 5 Base application theme, dependent on API level. This theme is replaced 6 by AppBaseTheme from res/values-vXX/styles.xml on newer devices. 7 --> 8 <style name="AppBaseTheme" parent="android:Theme.Light"> 9 <!-- 10 Theme customizations available in newer API levels can go in 11 res/values-vXX/styles.xml, while customizations related to 12 backward-compatibility can go here. 13 --> 14 </style> 15 16 <!-- Application theme. --> 17 <style name="AppTheme" parent="AppBaseTheme"> 18 <!-- All customizations that are NOT specific to a particular API-level can go here. --> 19 </style> 20 21 <style name="GreenButton"> 22 <item name="android:layout_width">wrap_content</item> 23 <item name="android:layout_height">wrap_content</item> 24 <item name="android:background">@drawable/button_green</item> 25 <item name="android:textColor">@color/button_green_color</item> 26 </style> 27 28 29 <style name="OrangeButton"> 30 <item name="android:layout_width">wrap_content</item> 31 <item name="android:layout_height">wrap_content</item> 32 <item name="android:background">@drawable/button_orange</item> 33 <item name="android:textColor">@color/white</item> 34 </style> 35 </resources>
大家可能已经注意到了,上述GreenButton的style中还包含一个button_green_color的颜色,实际上,它也是一个xml文件,我们在res目录下新建一个color目录,用于存放我们自定义的color资源文件。

1 button_green_color.xml: 2 <?xml version="1.0" encoding="utf-8"?> 3 <selector xmlns:android="http://schemas.android.com/apk/res/android"> 4 <item android:state_selected="true" android:color="@color/white" /> 5 <item android:state_focused="true" android:color="@color/white" /> 6 <item android:state_pressed="true" android:color="@color/white" /> 7 <item android:color="@color/" /> 8 </selector>
现在,使用自定义的button就很简单了,例如:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
1 <Button 2 style="@style/GreenButton" 3 android:text="GreenButton"/> 4 5 <Button style="@style/OrangeButton" 6 android:text="OrangeButton"/>
