Android get color as string value

Questions:

If i defined a color in resources

<resources>
    <color name="someColor">#123456</color>
</resources>

it’s possible to set color by its id, like

view.setTextColor(R.color.someColor);

Is it also possible to get color string value from colors.xml?

Something like

colorStr = getColor(R.color.someColor);
// -> colorStr = "#123456"

If yes, can anybody give an example?

Thank you

How to&Answers:

This is your answer

colorStr=getResources().getString(R.color.someColor);

you will get

 colorStr = "#123456"

Answer:

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:

The answers provided above are not updated.

Please try this one

String colorHex = "#" + Integer.toHexString(ContextCompat.getColor(getActivity(), R.color.dark_sky_blue) & 0x00ffffff);

Answer:

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:

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 );

Answer:

For API above 21 you can use

getString(R.color.color_name);

This will return the color in a string format.
To convert that to a color in integer format (sometimes only integers are accepted) then:

Color.parseColor(getString(R.color.color_name));

The above expression returns the integer equivalent of the color defined in color.xml file

Answer:

I don’t think there is standard functionality for that. You can however turn the return in value from getColor() to hex and turn the hex value to string.

hex 123456 = int 1193046;

Answer:

This is how I’ve done it:

String color = "#" + Integer.toHexString(ContextCompat.getColor
(getApplicationContext(), R.color.yourColor) & 0x00ffffff);

Answer:

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:

If you don’t want to use ContextCompat or SuppressLint, simply add a string resource right under your color.

Instead of

<color name="text_color">#FFFFFF</color>

Use

<color name="text_color">#FFFFFF</color>
<string name="text_color_string">#FFFFFF</string>

Your code does get more repetitive but it’s much cleaner. Besides, forgeting to updating the string after changing color is almost impossible since they are right next to each other.
