我创建了1个xml:

 <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">

        <item android:state_pressed="true"><shape android:shape="line">

                <!-- Draw a 2dp width border around shape -->
                <stroke android:width="1dp" android:color="@color/blue" />
            </shape>
               <!-- Overlap the left, top and right border using background color  -->
        <item
            android:bottom="1dp"
            >
            <shape android:shape="rectangle">
                <solid android:color="@color/white"/>
            </shape>
        </item> <!-- pressed -->
        </item>
        <item android:state_focused="true"><shape android:shape="rectangle">

                <!-- Draw a 2dp width border around shape -->
                <stroke android:width="1dp" android:color="@color/blue" />
            </shape></item>
     <!-- focused -->
        <item><shape android:shape="rectangle">

                <!-- Draw a 2dp width border around shape -->
                <stroke android:width="1dp" android:color="@color/orange" />
            </shape></item>
     <!-- default -->

    </selector>

但是它给了我矩形，我只想要LINE @bottom

but it giving me RECTANGLE i just want LINE @bottom

推荐答案

在drawable文件夹中创建新的xml文件. 可以说

Create the new xml file inside drawable folder. lets say

a.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@android:color/transparent" /> <!--background color of box-->
        </shape>
    </item>

    <item
        android:top="-2dp"
        android:right="-2dp"
        android:left="-2dp">
        <shape>
            <solid android:color="@android:color/transparent" />
            <stroke
                android:width="1dp"
                android:color="<Focus color>" />  <!-- color of stroke -->
        </shape>
    </item>
</layer-list>

在drawable中创建另一个新的xml文件，可以说

Create another new xml file in drawable, lets say

b.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@android:color/transparent" /> <!--background color of box-->
        </shape>
    </item>

    <item
        android:top="-2dp"
        android:right="-2dp"
        android:left="-2dp">
        <shape>
            <solid android:color="@android:color/transparent" />
            <stroke
                android:width="1dp"
                android:color="#8AC42F" />  <!-- color of stroke -->
        </shape>
    </item>
</layer-list>

在drawable中创建另一个新的xml文件. 可以说

Create another new xml file in drawable. lets say

c.xml

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

尝试此代码.

这是一个选择器文件.必须使其成为edittext的背景. 选择器会根据其(编辑文本)状态自动在两个可绘制文件之间切换.

this is a selector file. it has to be made background to the edittext. selector automatically switches between two drawable file acording to its (edittext's) state.

使用 此 EditText

<EditText
    android:id="@+id/id_Login_emal_et"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="5dp"
    android:background="@drawable/c"
    android:ems="10"
    android:padding="10dip"
    android:hint="Email"
    android:inputType="textEmailAddress"
    >
