圆角+边框 EditText

在Drawable中建立xml文件：

    rounded_edittext.xml

 <?xml version="1.0" encoding="utf-8"?>
 <shape xmlns:android="http://schemas.android.com/apk/re/android"
     android:shape="rectangle"
     android:padding="8dip">
     <!-- 底色 -->
     <solid android:color="#FFFFFF"/>
     <!-- 圆角的角度 -->
     <corners android:bottomRightRadius="3dip"
         android:bottomLeftRadius="3dip"
         android:topLeftRadius="3dip"
         android:topRightRadius="3dip"/>
 </shape>

    rounded_edittext_focused.xml

 <?xml version="1.0" encoding="utf-8"?>
 <shape xmlns:android="http://schemas.android.com/apk/res/android"
     android:shape="rectangle"
     android:padding="8dip">
     <solid android:color="#FFFFFF"/>
     <!-- 边框色 -->
     <stroke android:width="2dip" android:color="@color/edittext_focused_stroke_color" />
     <corners
         android:bottomRightRadius="3dip"
         android:bottomLeftRadius="3dip"
         android:topLeftRadius="3dip"
         android:topRightRadius="3dip"/>
 </shape>

    rounded_edittext_states.xml

 <?xml version="1.0" encoding="utf-8"?>
 <selector xmlns:android="http://schemas.android.com/apk/res/android">
     <item android:state_pressed="true"
         android:state_enabled="true"
         android:drawable="@drawable/rounded_edittext_focused" />
     <item android:state_focused="true"
         android:state_enabled="true"
         android:drawable="@drawable/rounded_edittext_focused" />
     <item android:state_enabled="true"
         android:drawable="@drawable/rounded_edittext" />
 </selector>

 在实际应用中，在EditText指定BackgroundDrawable就可以了。
