How to set image darkly without background option?

Question

Is There any solution to set image darkly?

<LinearLayout
            android:background="@drawable/terminalImage"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

I wrote like this, so I can't use background anymore. Is there any option or solution to set background image darkly?

I guess placing view with background color #55000000 in front of your image will be simplest (but dirty, yes) solution for you. Modifying first 2 numbers you can change transparency. — Northern Poet, Nov 02 '17 at 08:12
@NorthernPoet, not really: the simplest way is just to use `Drawable#setColorFilter` method with `LightingColorFilter` parameter (or even easier `Drawable#setColorFilter(int color, PorterDuff.Mode mode)`) — pskink, Nov 02 '17 at 08:20
