Android: .getDrawable deprecated, minimum SDK 17 solution?

Question

I am currently reading through the Head First Android Development book.

This question is regarding code in chapter 13, with a link to the specific file below:

https://github.com/dogriffiths/HeadFirstAndroid/blob/master/chapter14/BitsAndPizzas/app/src/main/java/com/hfad/bitsandpizzas/CaptionedImagesAdapter.java

The code below uses a deprecated method, .getDrawable:

Drawable drawable = cardView.getResources().getDrawable(imageIds[position]);

For new SDKs this can be resolved by changing the code to:

Drawable drawable = cardView.getResources().getDrawable(imageIds[position], null);

However, I cannot get the code working for a minimum SDK of 17, and have tried using ContextCompat. The previously used compatibility solution I found was deprecated.

Thank you

Answer 1

ContextCompat.getDrawable(Context context, int id) is not deprecated and is the correct method to use in this scenario.

If for whatever reason you don't want to use ContextCompat , you can always just use the same code it uses :

public static final Drawable getDrawable(Context context, int id) {
    final int version = Build.VERSION.SDK_INT;
    if (version >= 21) {
        return context.getDrawable(id);
    } else {
        return context.getResources().getDrawable(id);
    }
}
