How to create Drawable from resource

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.setCompoundDrawables().

So how can I convert an image resource to a Drawable?

In Kotlin you can do like this:

binding.floatingActionButton.setImageDrawable(
            AppCompatResources.getDrawable(this, android.R.drawable.ic_delete))

Where binding is a root View and this refer to Context, You need import

import androidx.appcompat.content.res.AppCompatResources

Your Activity should have the method getResources. Do:

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

As of API version 21 this method is deprecated and can be replaced with:

Drawable myIcon = AppCompatResources.getDrawable(context, R.drawable.icon);

If you need to specify a custom theme, the following will apply it, but only if API is version 21 or greater:

Drawable myIcon =  ResourcesCompat.getDrawable(getResources(), R.drawable.icon, theme);

The getDrawable (int id) method is deprecated as of API 22.

Instead you should use the getDrawable (int id, Resources.Theme theme) for API 21+

Code would look something like this.

Drawable myDrawable;
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
    myDrawable = context.getResources().getDrawable(id, context.getTheme());
} else {
    myDrawable = context.getResources().getDrawable(id);
}

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

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

If you are inheriting from a fragment you can do:

Drawable drawable = getActivity().getDrawable(R.drawable.icon)

This code is deprecated:

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

Use this instead:

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

Get Drawable from vector resource irrespective of, whether its vector or not:

AppCompatResources.getDrawable(context, R.drawable.icon);

Note:
ContextCompat.getDrawable(context, R.drawable.icon); will produce android.content.res.Resources$NotFoundException for vector resource.

I would just like to add that if you are getting "deprecated" message when using getDrawable(...) you should use the following method from the support library instead. 

ContextCompat.getDrawable(getContext(),R.drawable.[name])

You do not have to use getResources() when using this method.

This is equivalent to doing something like

Drawable mDrawable;
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
    mDrawable = ContextCompat.getDrawable(getContext(),R.drawable.[name]);
} else {
    mDrawable = getResources().getDrawable(R.id.[name]);
}

This works on both pre and post Lollipop versions.

If you are trying to get the drawable from the view where the image is set as, 

ivshowing.setBackgroundResource(R.drawable.one);

then the drawable will return only null value with the following code...

   Drawable drawable = (Drawable) ivshowing.getDrawable();

So, it's better to set the image with the following code, if you wanna retrieve the drawable from a particular view.

 ivshowing.setImageResource(R.drawable.one);

only then the drawable will we converted exactly.
