To implement splitActionBar:

Just add android:uiOptions="splitActionBarWhenNarrow" to your activity tag in theAndroidManifest.xml like this...

NOTE: It is available ONLY for handset devices with a screen width of 400dp.

To create a custom bottom toolbar:

If you want to set it for all devices, please check my answer (find a post starting with Creating custom bottom toolbar) here:

Creating custom bottom toolbar

I've already created a simple app which should demonstrate you how to begin

Creating a custom ViewGroup

Here's my activity_main.xml layout file:

As you can see my parent ViewGroup is RelativeLayout, which simply allows me to create a view at the bottom of screen.

Notice that I set layout padding to zero (I think: setting layout margin to zero here is not necessary, the same effect). If you'd change it, the toolbar won't use full width and it won't stick with bottom of the screen.

Then I added a Linear Layout with hardcoded height which is:

          android:layout_height="40dp" 

I wanted it, that my bottom toolbar would take full available width so I set it as match_parent.

Next, I added some ImageButton views with images from Android library.

There you have two possibilities:

• if you really want to have a toolbar like in above example just remove in every ImageButton view this line:

        android:layout_weight="1" 

After removing weights and some buttons you would get a view pretty similar to expected:

• if you want to take the full width and make every button with the same size use in your project weight as in this mine example.

Now let's go to my AndroidManifest.xml

In that file I'd added as you can see only one additional line:

         android:windowSoftInputMode="stateVisible|adjustResize"> 

to make sure that device keyboard won't hide my custom bottom toolbar.
