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。
