Custom Translucent Android ActionBar

Question

I\'ve been scouring the interwebs (e.g. Android documentation, answers here, etc.) for the answer to what I thought would be a fairly trivial question. How do you achieve a

Answer 1

I just like to share with you the steps I took to achieve this:

1) At the OnCreate of your activity,

getWindow().requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY);

then

getWindow().setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION,
            WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);

This is done before setContentView.

2) After setContentView, you can do the following

 getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.argb(0, 100, 181, 246)));

Where the alpha value of 0 means it is fully transparent.
