Is there a transparent color code?

Question

I'm looking for my actionBar to be transparent. I only have searchView in it and it's in my MapActivity, I just want the searchView and the "back pressed" buttons to be visible. Which transparency # code do I use to fill into the following:

 getSupportActionBar().setBackgroundDrawable(new ColorDrawable(parseColor("#")));

https://developer.android.com/reference/android/graphics/drawable/ColorDrawable.html#attr_android:color May be a color value, in the form of "#rgb", "#argb", "#rrggbb", or "#aarrggbb". — Toris, Nov 28 '17 at 19:56

Transparency is usually the first channel on a color spec (ARGB) so you may declare it as #FF000000 (Full Transparent black color) — Marcos Vasconcelos, Nov 28 '17 at 20:19
@MarcosVasconcelos maybe a typo but #FF000000 is not transparent. It's opaque black. — Toris, Nov 28 '17 at 20:23
So its #00000000 ?? I always forget thats why I always use #88000000 — Marcos Vasconcelos, Nov 28 '17 at 20:32
Yes for #00000000. And NB: setBackgroundDrawable(Drawable background) This method was deprecated in API level 16. use setBackground(Drawable) instead https://developer.android.com/reference/android/view/View.html#setBackgroundDrawable(android.graphics.drawable.Drawable) NB2: background Drawable: The Drawable to use as the background, or null to remove the background — Toris, Nov 28 '17 at 20:43
I wonder why I'm receiving down votes? The question is very clear. I'm just asking the color code for transparency. It's not too complicated of a question, don't overthink it. — iBEK, Nov 28 '17 at 21:01

Android supports the #AARRGGBB color format.

A = alpha, R = Red, G = Green, B = Blue

To make some View transparent use #00000000.
First 00 are alpha.

You can also use the short form: #ARGB. So, **#0000**. – Phantômaxx Nov 29 '17 at 08:15
