本文主要分享圆角边框与圆角背景的实现方式。该方式的实现,需要了解shape的使用,该部分的详细介绍,请阅读博客http://blog.youkuaiyun.com/mahoking/article/details/23672271。文中有较详细的介绍。

如下是演示的shape_layout.xml模板。
- <?xml version="1.0" encoding="utf-8"?>
- <shape xmlns:android="http://schemas.android.com/apk/res/android" >
- <!-- 填充色 -->
- <solid android:color="#CCFF99"/>
- <!-- 圆角 -->
- <corners android:radius="10dp"/>
- </shape>
为了显示的好看与协调,本案创建了多个shape_*.xml文件,各个shape_*.xml文件只是solid填充色的配置不同,读者可以根据自己的设计与喜好自行搭配。在本文的而最后,会展示相应Demo截图。
- <?xml version="1.0" encoding="utf-8"?>
- <shape xmlns:android="http://schemas.android.com/apk/res/android" >
- <!-- 填充色 -->
- <solid android:color="#FF9999"/>
- <!-- 圆角 -->
- <!-- android:radius 设置角的弧度,值越大角越圆-->
- <corners android:radius="10dp"/>
- </shape>
创建Activity(RoundCornerActivity),对应的布局文件为activity_01_round_corner.xml。
RoundCornerActivity
- /**

- public class RoundCornerActivity extends Activity{
- @Override
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.activity_01_round_corner);
- }
- }
activity_01_round_corner.xml

切忌不要忘记在AndroidManifest.xml中注册该Activity。
- <application
- android:allowBackup="true"
- android:icon="@drawable/uisharing_ico"
- android:label="@string/app_name"
- android:theme="@style/AppTheme" >
- <activity
- android:name="com.mahaochen.app.uisharing.example01.RoundCornerActivity"
- android:screenOrientation="portrait"
- android:label="@string/app_name">
- <intent-filter>
- <action android:name="android.intent.action.MAIN" />
- <category android:name="android.intent.category.LAUNCHER" />
- </intent-filter>
- </activity>
- </application>
运行该项目,效果如下:
