Android - set an image using @android:drawable/AnImage programmatically

Question

I know how to use @drawable but how do I set @android:drawable/ic_image in code?

in XML, it would be

android:icon="@drawable/my_image"

or

android:icon="@mipmap/my_image"

and for android:drawable, it would be:

android:icon="@android:drawable/ic_menu_delete"

but how to do the latest in code to set an image?

And which should I use?

This will help you out. Don't use getResource().getDrawable(). Its deprecated.

So basically:

 Drawable drawable = ContextCompat.getDrawable(this, R.drawable.your_drawable);
    img.setBackgroundDrawable(drawable);

For android drawables you do:

ContextCompat.getDrawable(this, android.R.drawable.your_drawable);

For Mipmaps:

ContextCompat.getDrawable(this, R.mipmap.your_drawable);

You can do it like this code:

img.setImageDrawable(getResources().getDrawable(R.drawable.ic_image, null));

@ArnoldB this getDrawable(id) is deprecated. but my suggestion is getDrawable(id, theme). In my answer I send null as second parameter. – Fred Dec 30 '15 at 23:02
Yes. But still that does not make it correct. The way Google wants you to do it is the way I put in as an answer. That method will most likely get deprecated too as they have methods for themes with ResourcesCompat too. He asked for the correct way. – Arnold Balliu Dec 30 '15 at 23:05
No problem. This has been very confusing for a while since Google keeps changing it. I don't even know why they don't have it down yet... really annoying. – Arnold Balliu Dec 30 '15 at 23:13

to use Android resources you should use "android.R" prefix like in resource name. this is code example:

    view.setBackgroundResource(android.R.drawable.ic_menu_delete);
