title: Text gone when I set background for button
body: <pre><code>&lt;Button
                          android:layout_width="0px"
                          android:layout_height="fill_parent"
                          android:layout_weight="2"
                          android:background="@drawable/banner_btn_bg"
                          android:text="ABCXYZDEF"
                          android:gravity="center"
                          android:textColor="@android:color/white"
                          android:textSize="20sp" /&gt;
  </code></pre>
  
  <p>I want to set background for my button, but the text will be gone when I set it. I wonder why my text will appear when I set background to any color but it will be gone when I set image? Btw, the image is a grey one not white as text.How can I fix that?</p>
