Define a custom color variable

I want to change some button colors globally in my code. I cannot seem to fine a way to define a color variable and then assign a color value to that variable.

I tried this Color SelectedColor = new Color();

      f1.setBackgroundColor(Color.rgb(0, 0, 100));

I want to use ColorSelected in place of the RGB value so I can edit the value at start up.

          f1.setBackgroundColor(Color.ColorSelected);

You must add attribute type="color" in the color tag:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color type="color" name="menu_background">#666666</color>
</resources>

So, you can use the color in xml file as "@color\menu_background" and also from java code.

"I cannot seem to fine a way to define a color variable and then assign a color value to that variable."

Here is how you can define a color variable:

int selectedColor = Color.rgb(0, 0, 100);

and use it:

f1.setBackgroundColor(selectedColor);

you can use values/colors.xml. For instance

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="menu_background">#666666</color>
</resources>
