How to create Drawable from resource

Question

I have an image res/drawable/test.png (R.drawable.test).
I want to pass this image to a function which accepts Drawable, e.g. mButton.set

Answer 1

You must get it via compatible way, others are deprecated:

Drawable drawable = ResourcesCompat.getDrawable(context.getResources(), R.drawable.my_drawable, null);

Answer 2

This code is deprecated:

Drawable drawable = getResources().getDrawable( R.drawable.icon );

Use this instead:

Drawable drawable = ContextCompat.getDrawable(getApplicationContext(),R.drawable.icon);
