Border color on Android button

Question

I have a button created and have set the background color and text color as can be seen below. My question is: how do I set the buttons border color? I want to set the border color to white

Here is the button in my res -> layout -> main_nav.xml

<Button          android:id="@+id/btn_emergency"         style="@style/buttonStyle"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_weight="1"         android:text="Contact and Emergency"          android:onClick="onClickHandleStates" /> 

And here is its associated style in res -> values -> styles. The first 2 "items" work fine on their own. The final "item" was my attempt at changing button border to white without success.

<!-- The button styles --> <style name="buttonStyle">     <item name="android:textColor">#ffffff</item>     <item name="android:background">#80000000</item>      <item name="android:button">         <shape             android:shape="rectangle" >             <stroke                 android:width="0.5dp"                 android:color="#ffffff" />           </shape>     </item> </style> 

Answer 1

Use the <stroke> element. Add this xml file in res/drawable folder as button_border.xml:

 <?xml version="1.0" encoding="utf-8"?>   <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="rectangle">     <gradient android:startColor="#FFFFFF"         android:endColor="#00FF00"        android:angle="270" />     <corners android:radius="3dp" />     <stroke android:width="5px" android:color="#ffffff" />  </shape> 

then call this by

<Button    android:id="@+id/button1"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_margin="10dp"    android:background="@drawable/button_border"    android:text="Button"  />
