我用过这个。
<color name="edt_pressed">#99CBFF</color>
<color name="edt_focused">#CEF7F6</color>
<color name="edt_default">#000000</color>
gradient_edt_focused
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke android:width="1dip" android:color="@color/edt_focused" />
</shape>
edt_border.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:drawable="@layout/gradient_edt_pressed"/>
<item android:state_focused="true" android:drawable="@layout/gradient_edt_focused"/>
<item android:drawable="@layout/gradient_edt_default"/>
</selector>
activity_main.xml
<EditText
android:id="@+id/uname"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="true"
android:background="@layout/textview_border"/>
现在边框工作正常,但在输入文本时,背景颜色为黑色。
