getColor(int id) deprecated on Android 6.0 Marshmallow (API 23)

The Resources.getColor(int id) method has been deprecated.

@ColorInt
@Deprecated
public int getColor(@ColorRes int id) throws NotFoundException {
    return getColor(id, null);
}

What should I do?

Solution 1:

Starting from Android Support Library 23,
a new getColor() method has been added to ContextCompat.

Its description from the official JavaDoc:

Returns a color associated with a particular resource ID

Starting in M, the returned color will be styled for the specified Context's theme.

So, just call:

ContextCompat.getColor(context, R.color.your_color);

You can check the ContextCompat.getColor() source code on GitHub.

Solution 2:

tl;dr:

ContextCompat.getColor(context, R.color.my_color)

Explanation:

You will need to use ContextCompat.getColor(), which is part of the Support V4 Library (it will work for all the previous APIs).

ContextCompat.getColor(context, R.color.my_color)

If you don't already use the Support Library, you will need to add the following line to the dependencies array inside your app build.gradle (note: it's optional if you already use the appcompat (V7) library):

compile 'com.android.support:support-v4:23.0.0' # or any version above

If you care about themes, the documentation specifies that:

Starting in M, the returned color will be styled for the specified Context's theme

Solution 3:

I don't want to include the Support library just for getColor, so I'm using something like

public static int getColorWrapper(Context context, int id) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        return context.getColor(id);
    } else {
        //noinspection deprecation
        return context.getResources().getColor(id);
    }
}

I guess the code should work just fine, and the deprecated getColor cannot disappear from API < 23.

And this is what I'm using in Kotlin:

/**
 * Returns a color associated with a particular resource ID.
 *
 * Wrapper around the deprecated [Resources.getColor][android.content.res.Resources.getColor].
 */
@Suppress("DEPRECATION")
@ColorInt
fun getColorHelper(context: Context, @ColorRes id: Int) =
    if (Build.VERSION.SDK_INT >= 23) context.getColor(id) else context.resources.getColor(id);

Solution 4:

In Android Marshmallow many methods are deprecated.

For example, to get color use

ContextCompat.getColor(context, R.color.color_name);

Also to get drawable use

ContextCompat.getDrawable(context, R.drawable.drawble_name);

Solution 5:

For all the Kotlin users out there:

context?.let {
    val color = ContextCompat.getColor(it, R.color.colorPrimary)
    // ...
}
