In Android How To Make Translucent Status Bar With Black Background Navigation Button

Guys I want to have translucent status bar with black background navigation buttons. Just like Netflix App as shown in picture. I tried really hard to find any way but I failed to achieve this. Any Idea?

Add in styles.xml in Base Application style
Change status bar color : <item name="android:statusBarColor">#color/blackColor</item>
For Translucent status bar : <item name="android:windowTranslucentStatus">true</item>
For navigation bar color : <item name="android:navigationBarColor">#color/blackColor</item>
in layout file use : android:fitsSystemWindows="true" in root layout.

Customize the part on top of the action bar

I'd like to know what's the name of the part on top of the action bar (where the time is displayed alongside the battery, wifi, etc), and how can its color be changed ?
Thanks !

That's the status bar.
Just add colorPrimaryDark item to your theme in styles.xml
<item name="colorPrimaryDark">#color/primary.dark</item>

How to hide app title in action bar

i have an action bar scherlock where i want to show logo without app title. I've just added in manifest android:logo tag and some code getSupportActionBar().setDisplayShowTitleEnabled(false) in my activity thats hide my title. It seems to work fine, but when app was started a title displays in a few seconds, how i can resolve this?

just try this in order to hide title bar.
Use this in styles.xml file

I suggest use custom title bar.

Actionbar menu item background on select

I am using sherlock actionbar and made custom action bar using differnt color (blue) . When there are menu items . as i click on menu item . items background turns in to gray . Not able to point which attribute of the style is making this effect had checked the most possibility . any help would be appreciated

after some analysis found following answer
<item name="selectableItemBackground">#null</item>
<item name="android:selectableItemBackground">#null</item>
<item name="actionBarItemBackground">#null</item>
<item name="android:actionBarItemBackground">#null</item>
The issue is you need to override these attributes in your application. donot try changing in actionbar apk libary. that was the point i missed while fixing this.

make android HomeAsUp icon disappear on demand

In my android app, in the Action Bar, next to the < image is an icon. I want to make it invisible/gone ondemand dynamically. How do I do that? The icon is actually defined as follows (this should help you realize where in the action bar I am talking about).
<style name="MyAppName.LogoTheme.LogoActionBar" parent="MyAppName.Theme.ActionBar">
<item name="android:displayOptions">showHome|homeAsUp</item>
<item name="android:icon">#drawable/my_icon</item>
I tried the following, but nothing.
this.getActionBar().setDisplayHomeAsUpEnabled(false);
this.getActionBar().setLogo(null);
this.getActionBar().setDisplayUseLogoEnabled(true);

In Java, call setDisplayShowHomeEnabled(false) and setDisplayShowTitleEnabled(false) on your ActionBar.
