Customize Navigation Drawer Action Bar (App Compact) in android

I want to customize navigation drawer app compact action bar, I want to remove app icon from that and want to make its title center in action bar.
I have applied all solutions , but nothing is working with all the conditions.
Please give me some clue for applying it correctly

You should creat a customize action bar. Then, if you want you can add a button that can open and close your drawerlayout.

I have solved my problem. As mentioned, I have two problems, and I solved that in following way :
1) For making title centre, we need to make custom layout of action bar, and need to remove action bar title.
2) for remove app icon from action bar, we need to set android:icon property of that activity in manifest with transparent image or colour.

How to use a different icon for action bar

I made an icon for my Android app but I want to use a different file for the action bar. So on icon for app section, and one icon for action bar. How can I do that ?

From official documentation:
By default, the system uses your application icon in the action bar,
as specified by the icon attribute in the or
element. However, if you also specify the logo attribute, then the
action bar uses the logo image instead of the icon.

Android: Homescreen Icons different than Menu Icons

Is it possible in Android to declare a HomescreenIcon for the user e.g. colored and inside the application the same Icon shown in the Action Bar just white?
In my case these are two different images i want to show. I defined the icon inside the AndroidManifest.xml but i can not find any option to change it for the ActionBar. It is always the same.

Yes, you can use android:logo in your manifest to provide the action bar image and android:icon to provide home screen icon. Both of them should be set to a drawable resource and can point to a different resources.

Way to maximize screen area

I have this screen structure in my app:
Which is tremendous waste of area. Mainly in the system bar and the action top bar.
I would like to:
Move the app logo and title to the system area
Narrow the height of the tabs
Move the menu to the bottom action bar
To get something like this:

You can do one thing remove the title and appicon from this TabLayout.
Use for your activity in androidmanifest.xml
android:theme="#android:style/Theme.NoTitleBar"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
Using this parameters your layout will be looking like this see it

I managed to hide the main action bar. As it is described in Android Developer's site:
If you'd like to hide the main action bar at the top, because you're
using the built-in navigation tabs along with the split action bar,
call setDisplayShowHomeEnabled(false) to disable the application icon
in the action bar. In this case, there's now nothing left in the main
action bar, so it disappears and all that’s left are the navigation
tabs at the top and the action items at the bottom, as shown by the
second device in figure 3.
That's necessary, but not enough, because the main action bar still shows the title and the menu icon on the right. Two more steps are required:
Hide the icon and Title
setDisplayShowTitleEnabled(false);
Do not create a menu in onCreateOptionsMenu()
Now the main action bar is empty and it indeed dissapears. The tabs still show. The menu is lost, but you can create a button somewhere in your screen to act as menu, even you can use the same icon.
Tab Height
And I found out that the tab height can be controlled through XML style. Adding this to the styles.xml inside the app style tag
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
<item name="android:actionBarSize">35dp</item>
</style>
System Bar
It seems to be that the system bar is, as its name suggest, for system only use, not user. I did not find any clue to whether the elements in there can be modified (exception being notification icons from services)

Custom home button on ActionBar

I am using ActionBar Sherlock library. So, to change the default home button. I did this:
<style name="Theme.mTheme" parent="android:Theme.Sherlock.Light.DarkActionBar">
<item name="android:homeAsUpIndicator">#drawable/custom_home</item>
</style>
which didn't work
So, i added this too:
<item name="homeAsUpIndicator">#drawable/custom_home</item>
now its working. I am having this custom home icon/button on every ActionBar. But in 1 of my Activities i have this in code:
actionBar.setIcon(R.drawable.options_holo_dark);
When i am in that Activity, I can see the icon which i set programatically ie.., options_holo_dark. The 1 which i set in Theme ie.., custom_home is not visible. But the Icon has moved to the Right as if its giving space on the left to the icon i set in theme(though not visible).
This is what i am getting now:
So, how can i avoid that empty space on the left side of the Home Icon?
Thank You

Theme item android:homeAsUpIndicator (and homeAsUpIndicator for ActionBarSherlock) sets drawable for the up icon - that's the little arrow pointing to left that is displayed next to the app icon when you have called setDisplayHomeAsUpEnabled(true) on the action bar.
The size of the up drawable defines the left margin for the app icon (logo). By default its dimensions are 16dp x 16dp. If you put there wider drawable the gap between edge of the screen and the app icon would be wider even though the up icon is not displayed at the moment.
If you want to change the app icon (logo). Use setLogo(int) or setLogo(Drawable) method of ActionBar. Don't forget to call setDisplayUseLogoEnabled(true) too - this method toggles between displaying app icon and custom logo. Also you can define the logo in manifest in attribute android:logo of <application> and <activity> tags and set in theme that you want to use logo instead of app icon in the action bar.
