Android: Tint using DrawableCompat

Question

I'm trying to tint an image prior to Android API level 21. I've successfully tinted items using:

<android:tint="@color/red"/>

However, I can't seem to figure out how to do this through code on an ImageView:

Drawable iconDrawable = this.mContext.getResources().getDrawable(R.drawable.somedrawable);
DrawableCompat.setTint(iconDrawable, this.mContext.getResources().getColor(R.color.red));
imageView.setImageDrawable(iconDrawable);

I've tried setting the TintMode but this seems to make no different. Am I using the v4 compatibility class DrawableCompat incorrectly?

Answer 1

In case anyone needs to use DrawableCompat's tinting without affecting other drawables, here's how you do it with mutate():

Drawable drawable = getResources().getDrawable(R.drawable.some_drawable);
Drawable wrappedDrawable = DrawableCompat.wrap(drawable);
wrappedDrawable = wrappedDrawable.mutate();
DrawableCompat.setTint(wrappedDrawable, getResources().getColor(R.color.white));

Which can be simplified to:

Drawable drawable = getResources().getDrawable(R.drawable.some_drawable);
drawable = DrawableCompat.wrap(drawable);
DrawableCompat.setTint(drawable.mutate(), getResources().getColor(R.color.white));
