title: Changing the background color of an EditText issue
body: <p>I have a simple layout with an edittext.</p>
  
  <p>When I set the background of the <code>EditText</code> to a color</p>
  
  <pre><code>    &lt;EditText
          android:id="@+id/et"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:layout_marginTop="5dp"
          android:background="@android:color/white" /&gt;
  </code></pre>
  
  <p>Then a strange thing happens when the edittext gains focus, the background color of the layout changes(!).</p>
  
  <p>I need to change the background color dynamically, and I have the same result after calling:</p>
  
  <pre><code>subject.setBackgroundColor(Color.parseColor(mycolor));
  </code></pre>
  
  <p>I have also tried the following method :</p>
  
  <pre><code>subject.setBackground(new ColorDrawable(Color.parseColor(mycolor)));
  </code></pre>
  
  <p>The result was the same.</p>
  
  <p>Basically I want to change the background color of an Edittext in runtime. </p>
