AndroidEditText的邊框顏色及有無焦點下不同狀態

準備三個xml文件，資源類型要選對

bg_edittext.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_window_focused="false"
        android:drawable="@drawable/bg_edittext_normal" />
    <item android:state_focused="true" android:drawable="@drawable/bg_edittext_focused" />
</selector>

bg_deittext_focused.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FFFFFF" />
    <!-- 獲得焦點-->
    <corners android:radius="3dip"/>
    <stroke
        android:width="1dip"
        android:color="#728ea3" />
</shape>  

bg_deittext_normal.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- 未獲得焦點-->
    <solid android:color="#FFFFFF" />
    <corners android:radius="3dip"/>
    <stroke
        android:width="1dip"
        android:color="#BDC7D8" />
</shape>

佈局文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <EditText
        android:padding="10dp"
        android:layout_width="match_parent"
        android:background="@drawable/bg_edittext"
        android:textSize="16sp"
        android:id="@+id/first_et"
        android:hint="小林未鬱"
        android:layout_height="wrap_content"/>

    <EditText
        android:padding="10dp"
        android:layout_width="match_parent"
        android:background="@drawable/bg_edittext"
        android:textSize="16sp"
        android:layout_below="@id/first_et"
        android:text=""
        android:layout_height="wrap_content"/>
</RelativeLayout>
