Explain why IDEA crossed out the line?

Question

Java

Good!
Actually, I set the text color in the adapter, I want it to use resources, it works, but I don’t understand why it looks like this

Answer 1

This is a deprecated method. Use ContextCompat.getColor(context, R.color.your_color);

Answer 2

IDEA highlights methods that oracle doesn't recommend using because of major flaws.

Answer 3

This method is marked as deprecated in the annotations, as decided by Google, the author of the Android OS. They love it, the "watchman syndrome" and the syndrome of unfinished actions are the characteristic features of this ecosystem.
It's best to avoid using these methods, but it will compile, and will likely work, if the device is not on a very new OS version.
