Question

If i defined a color in resources

    #123456

it\'s possible

Answer 1

It works for me!

String.format("#%06x", ContextCompat.getColor(this, R.color.my_color) & 0xffffff)

Answer 2

Add @SuppressLint("ResourceType") if an error occurs. Like bellow.

private String formatUsernameAction(UserInfo userInfo, String action) {
        String username = userInfo.getUsername();
        @SuppressLint("ResourceType") String usernameColor = getContext().getResources().getString(R.color.background_button);
        return "<font color=\""+usernameColor+"\">" + username
                + "</font> <font color=\"#787f83\">" + action.toLowerCase() + "</font>";
    }

Answer 3

Just for the sake of easy copypasta:

"#" + Integer.toHexString(ContextCompat.getColor(getActivity(), R.color.some_color));

Or if you want it without the transparency:

"#" + Integer.toHexString(ContextCompat.getColor(getActivity(), R.color.some_color) & 0x00ffffff);

Answer 4

All of the solutions here using Integer.toHexString() break if you would have leading zeroes in your hex string. Colors like #0affff would result in #affff. Use this instead:

String.format("#%06x", ContextCompat.getColor(this, R.color.your_color) & 0xffffff)

or with alpha:

String.format("#%08x", ContextCompat.getColor(this, R.color.your_color) & 0xffffffff)

Answer 5

Cause getResources().getColor need api > 23. So this is better: Just for the sake of easy copy & paste:

Integer.toHexString( ContextCompat.getColor( getContext(), R.color.someColor ) );

Or if you want it without the transparency:`

Integer.toHexString( ContextCompat.getColor( getContext(), R.color.someColor ) & 0x00ffffff );
