Question

I cannot figure out why this code will not work. Can anyone help? I am trying to get the button to use a custom color titled ‘greenstart’ and ‘greenend’. The colors have been created in the res/value/string.xml file. I have looked at similar questions but either they were left unanswered, unclear, or the solution did not work. Thanks in advance.

XML FILE SAMPLE:

<Button
   android:id="@+id/mycollection"
   android:layout_width="match_parent"
   android:layout_height="fill_parent"
   android:layout_weight="1" >

   <Gradient
      android:angle="270"
      android:endColor="@color/greenstart"
      android:startColor="@color/greenend" >
   </Gradient>
</Button>

Create a new xml file and put it in drawable and then add it to button as background

gradient.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
    <!--  Gradient Bg for listrow -->
   <gradient
      android:startColor="#f1f1f2"
      android:centerColor="#e7e7e8"
      android:endColor="#cfcfcf"
      android:angle="270" />
</shape>

layout.xml

 <Button
    android:id="@+id/Button01"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_weight="1"
    android:background="@drawable/gradient"
    android:text="Übernehmen" >
