doubts action bar, toolbar, etc
<p>Well, I'm trying to make an app that needs to have some sort of ActionBar, which only have to schedule and design once, and then serve me for all my APP activity.
I'm not sure how this works, need a little guidance please.</p>

<p>To give you an idea of what I want, I would like something like this:</p>

<p><a href="https://i.stack.imgur.com/RW0JO.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RW0JO.png" alt="example app"></a></p>

<p>A top, that is the general of the APP. And then below as well as a submenu with icons, with different options.</p>

<p>What exactly would have to use it? I've been tinkering with ActionBar but that it me for the top .. But to the other as you would?</p>

<p>Both want them to be static and are always in every activity of my APP, without having to copy and paste the code of each una..Que I guess and this somehow you are ready to embed it anywhere, programming only once.</p>
