Answer : Tim S. was much closer to a "correct" answer then the currently accepted one. If you want to have a 100% width, variable height background image done with CSS, instead of using cover (which will allow the image to extend out from the sides) or contain (which does not allow the image to extend out at all), just set the CSS like so: body { background-image: url(img.jpg); background-position: center top; background-size: 100% auto; } This will set your background image to 100% width and allow the height to overflow. Now you can use media queries to swap out that image instead of relying on JavaScript. EDIT: I just realized (3 months later) that you probably don't want the image to overflow; you seem to want the container element to resize based on it's background-image (to preserve it's aspect ratio), which is not possible with CSS as far as I know. Hopefully soon you'll be able to use the new srcset attribute on the img element...

Answer : You need to also create a ColorStateList for text colors identifying different states. Do the following: Create another XML file in res\color named something like text_color.xml . <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <!-- disabled state --> <item android:state_enabled="false" android:color="#9D9FA2" /> <item android:color="#000"/> </selector> In your style.xml , put a reference to that text_color.xml file as follows: <style name="buttonStyle" parent="@android:style/Widget.Button"> <item name="android:textStyle">bold</item> <item name="android:textColor">@color/text_color</item> <item name="android:textSize">18sp</item> </style> This should resolve your issue. 1.Create a color folder ...
