Java how to get color from color file in adroid studio

To get a color from a color resource file in Android Studio, you can use the getColor() method of the Resources class.

Here's an example of how to get a color from a color resource file in Android Studio:

int color = getResources().getColor(R.color.color_name);

In the above example, the getColor() method is used to get the color with the name color_name from the color resource file. The R.color class is a generated class that contains constants for all the colors in the resource file.

You can also use the getColor() method to get a color with a specific attribute, such as its alpha value. For example:

int color = getResources().getColor(R.color.color_name, null);

In this case, the second argument to the getColor() method is a Theme object, which can be used to specify the desired attributes of the color. If the null value is passed, the default attributes are used.

For more information on working with colors in Android Studio, you can refer to the documentation for the Resources class in the Android developer documentation.
