The android.content.res.TypedArray class provides a simple way to retrieve attributes values from a set of typed attributes defined in an XML resource. One of the methods available in this class is getColor(int index, int defaultValue), which retrieves a color attribute from the TypedArray object.
Here are some examples of how to use this method:
Example 1: TypedArray array = getContext().obtainStyledAttributes(R.style.MyTheme, new int[]{R.attr.colorPrimary}); int color = array.getColor(0, 0); // here we retrieve the colorPrimary attribute value from a theme and assign it to a variable
Example 2: TypedArray array = getResources().obtainTypedArray(R.array.my_colors); int color = array.getColor(2, 0); // here we retrieve the third color attribute value from an array of color resources and assign it to a variable
In both examples, we use the getColor method to retrieve a color attribute value from a TypedArray object. The first parameter is the index of the attribute we want to retrieve, and the second parameter is the default value to return if the attribute is not found or is not a color attribute.
The TypedArray class belongs to the android.content.res package library.
