Android getting a list of colors from resource
android, java, resources, xml
Solution
You can access the list of colors using reflection:
Field[] fields = Class.forName(getPackageName()+".R$color").getDeclaredFields();
for(Field field : fields) {
String colorName = field.getName();
int colorId = field.getInt(null);
int color = getResources().getColor(colorId);
Log.i("test", colorName + " => " + colorId + " => " + color);
}
Problem
I have a list of colours ``` <?xml version="1.0" encoding="utf-8"?> <resources> <color name="white">#FFFFFF</color> <color name="yellow">#FFFF00</color> <color name="fuchsia">#FF00FF</color> <color name="red">#FF0000</color> <color name="silver">#C0C0C0</color> <color name="gray">#808080</color> <color name="olive">#808000</color> <color name="purple">#800080</color> <color name="maroon">#800000</color> <color name="aqua">#00FFFF</color> <color name="lime">#00FF00</color> <color name="teal">#008080</color> <color name="green">#008000</color> <color name="blue">#0000FF</color> <color name="navy">#000080</color> <color name="black">#000000</color> </resources> ``` (I took this list from another question someone asked) What I want to do is get all the color names. I want the list so I can then populate the lot in a spinner. The pseudo code would be like this. ``` List ofColours = getListOfColors(R.color); for(int i = 0 ; i < ofColours.size() ; i ++) { String colour = getResources().getColor(ofColours.get(i)); addColourToSpinner(colour); } ``` What I want is the list of colours. I hope that explains it Cheers for all the help
