如何在android按鈕中添加png文件和邊框？

Question

這裏，混合按鈕，我已經使用

<?xml version="1.0" encoding="utf-8"?> 
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"> 
<item> 
    <bitmap 
     android:src="@drawable/stripes" 
     android:tileMode="repeat" 
     android:dither="true" 
     android:antialias="true" /> 
</item> 
</layer-list> 

而對於其他的按鍵我用

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle"> 
    <gradient android:startColor="@android:color/transparent" 
    android:endColor="@android:color/transparent" 
    android:angle="270" /> 
    <corners android:radius="3dp" /> 
    <stroke android:width="5px" android:color="#000000" /> 
</shape> 

現在我想周圍添加混合按鈕怎麼那黑色邊框去做？

Answer 1

在圖層列表中使用形狀項下的XML文件中像下面

<?xml version="1.0" encoding="utf-8"?> 
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item> 
     <bitmap 
      android:src="@drawable/stripes" 
      android:tileMode="repeat" 
      android:dither="true" 
      android:antialias="true" /> 
    </item> 
    <item> 
     <shape xmlns:android="http://schemas.android.com/apk/res/android" 
     android:shape="rectangle"> 
      <gradient android:startColor="@android:color/transparent" 
         android:endColor="@android:color/transparent" 
         android:angle="270" /> 
      <corners android:radius="3dp" /> 
      <stroke android:width="5px" android:color="#000000" /> 
     </shape> 
    </item> 
</layer-list> 

它會幫助你..

你是超級密切，你只需要添加形狀（爲您的邊框）<layer-list>

類似這樣的：

<?xml version="1.0" encoding="utf-8"?> 

    <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item> 
     <bitmap 
      android:src="@drawable/stripes" 
      android:tileMode="repeat" 
      android:dither="true" 
      android:antialias="true" /> 
    </item> 
    <item> 
     <shape xmlns:android="http://schemas.android.com/apk/res/android" 
      android:shape="rectangle"> 
       <gradient android:startColor="@android:color/transparent" 
        android:endColor="@android:color/transparent" 
        android:angle="270" /> 
     <corners android:radius="3dp" /> 
     <stroke android:width="5px" android:color="#000000" /> 
     </shape>  
    </item> 
</layer-list>
