How To Change Included Toolbar Title And Drawable?

I have a hard time finding on how to change the Toolbar title and it's drawable in every and each Activity.
There is something on Android Documentation that states that to minimize APK size. It is recommended to re-used components.
I create a separate layout, and <include layout=""/> to each of my Activities like Help, About , and etc. I also put android:label="Title" on Manifest File.
Toolbar.xml
My Main:
How do I access this included Toolbar DRAWABLE and TITLE in my Activities ?
Update: I removed ActionBar .

You are using Toolbar. So no need to do anything with ActionBar. Just set your Toolbar as supportActionBar. Then set title and icon to your Toolbar.
Use the below code:
mToolbar = (Toolbar)findViewById(R.id.Toolbar);
setSupportActionBar(mToolbar);
setTitle("About");
getSupportActionBar.setIcon(R.id.ic_arrow_back_black_24dp);
And, Remove all your mActionBar codes. Hope this helps.

well you set the support action to your custom toolbar,yet you ignore it and use mActionBar, see where i am going with this? setIcon , and setTitle should all be called relative to your custom toolbar.

Display Android 'Up Button' with small arrow and logo

I tried the following code from the Android documentation, to display the 'up button':
#Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_details);
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
... }
According to the documentation the 'up botton' should look like this.
However, on my phone with Android 4.2 it looks more like this.
The arrow is separated from the logo and takes too much place. How can I get the small arrow in combination with the logo?

you can use toolbar and use setNavigationIcon() method to change the navigation icon
toolbar.setNavigationIcon(R.drawable.SomeIcon);

SlideMenu with Transparent Actionbar

with below code , i make a Transparent Actionbar for my FragmentActivity & all fragments:
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
ActionBar actionBar = getActionBar();
actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#64000000")));
setContentView(R.layout.main_slidemenu);
.
.
.
}
But i have a problem with this , i need to SlideMenu just open under actionbar , but it open i all of layout.

You are probably looking for the ActionBar overlay mode.
Enable it for a single Activity by calling requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY); before setContentView(). Or in a theme by setting android:windowActionBarOverlay to true.

if you've used SlidingMenu library you could use :
setSlidingActionBarEnabled(false);
but according to the link you've provided you have used NavigationDrawer , with NavigationDrawer i think you could use layout_marginTop for your NavigationDrawer in it's layout xml and for better achievement , get your ActionBar height dynamically then set margin to that.
and also try removing line below:
getWindow().requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
i've used NavigationDrawer before without setting Layout_marginTop and Window.FEATURE_ACTION_BAR_OVERLAY and its below my ActionBar.

Removing left arrow from the actionbar in android?

I want to remove the left arrow from the action bar and only icon and title needed.
My code:
getSupportActionBar().setIcon(R.drawable.logo);
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle(R.string.dashboardtitle);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
But this doesn't remove the left arrow . Any help!!

According to specification android specification:
To enable the icon for up navigation (which displays the "up" indicator next to the icon), call setDisplayHomeAsUpEnabled(true) on your ActionBar:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
...
}
So you should set actionBar.setDisplayHomeAsUpEnabled(false);
UPDATE:
I test next code with ActionBar sherlock and it's work. There is no back arrow:
getSupportActionBar().setIcon(R.drawable.ic_launcher);
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle(R.string.about_event_location);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);

You need to add this to your actionBar theme. You can replace arrow image with your own image which can be transparent
<item name="android:homeAsUpIndicator">#drawable/action_arrow</item>

getActionBar().setHomeAsUpIndicator(R.drawable.action_arrow);
Where action_arrow is a 25x10px transparent png.
Same code for sherlock would be:
getSupportActionBar().setHomeAsUpIndicator(R.drawable.action_arrow);

#vivek: works great. I do not recommend to use #android:color/transparent as Tim Cooper said, because the Title is aligned to the left. So a empty image is better

In AndroidManifest.xml
remove the below code, which will remove back button from your ActionBar
android:parentActivityName=".Main.MainActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".Main.MainActivity" />
Just keep it like below:
<activity
android:name=".YourActivity"
android:label="#string/your_activity_label">
</activity>

Android statusbar overlay with ActionBar

I know that I can make the ActionBar overlay using requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY)
and can toggle/show the status bar in my screen (by switching between FLAG_FULLSCREEN and FLAG_FORCE_NOT_FULLSCREEN).
This works great. However, I don't want my layout moving when I toggle the status bar.
I know that I can make the status bar "overlay" (albeit not transparently) the content using:
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
This works also great, except for the (expected) consequence that, when using an ActionBar, the ActionBar gets half cut off - half of it is under the status bar basically.
So I am wondering, is there a way to "move the ActionBar down" by the status bar's height in this case?
I know that in worse case, I can do this with a custom view that lives within the layout, but I rather not do this (want to benefit from the ActionBar).
thanks!

so apparently, you can do this in Jellybean. google includes two examples in the api docs. here is a link: http://developer.android.com/reference/android/view/View.html#setSystemUiVisibility%28int%29
summary:
use setSystemUiVisibility on a view to toggle visibility (on jellybean+).

It's not perfect, but this is how I have achieved what you want:
In onCreate:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
Then:
private void hideStatusBar() {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
}
private void showStatusBar() {
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
I also have a style on the activity with the following:
<style name="readingStyle" parent="#style/Theme.Sherlock">
<item name="android:windowActionBarOverlay">true</item>
<item name="windowActionBarOverlay">true</item>
</style>
Your activity will shift down when the status bar shows, but I don't think it's too noticeable.

Why you dont make it in the Manifest
android:theme="#android:style/Theme.Black.NoTitleBar"
than you have no statusbar and more space for the Actionbar??

Put this method in onCreate() method activity:
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
