BackgroundResource邊框的頂部和底部

Question

其實我有這樣的代碼：

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" > 
    <solid 
     android:color="#ffffff" /> 
    <stroke 
     android:width="0.5dp" 
     android:color="#000000" /> 
</shape> 

它創建圍繞視圖中的邊界，但我只想做一個邊框的頂部和底部。

怎麼樣？

編輯：對不起，我忘了應該與工作狀態下按下

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

Answer 1

嘗試在繪製文件夾這個

bkg.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="#FF0000" /> 
    </shape> 
    </item> 
    <item android:bottom="5dp" android:top="5dp" > 
    <shape android:shape="rectangle"> 
     <solid android:color="#000000" /> 
    </shape> 
    </item>  
</layer-list> 

更改顏色和行程寬度根據您的要求。圖形編輯器

快拍：爲了這個問題在評論

定義itembkg。 XML如下

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:state_pressed="true" 
     android:drawable="@drawable/bkg" /> 
     // bkg.xml in drawable folder 
     // drawable in pressed state 
    <item android:state_focused="false" 
     android:drawable="@drawable/tvnormal" /> 
     // set a different drawable in normal state 
</selector> 

然後在您的視圖中添加以下屬性

android:background="@drawable/itembkg"

試試這個....

<?xml version="1.0" encoding="utf-8"?> 
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item > 
    <shape android:shape="rectangle"> 

     <padding android:top="1dp" 
       android:bottom="1dp" /> 
     <solid android:color="#000000"/> 


    </shape> 
    </item> 
    <item > 
    <shape android:shape="rectangle"> 

     <solid android:color="#ffffff"/> 

    </shape>
