how to make hamburger menu fully visible

by default half of hamburger is shown, as seen at the top left corner of the screenshot. I want to display full hamburger. code is taken from https://developer.android.com/training/implementing-navigation/nav-drawer.html. how can I do this?

Seems you are using very old technique to create Navigation Drawer. Its around 4 years old code and seems perfect regarding old version.
FYI, previously this kind of UI was done using DrawerLayout with ListView. But now android itself officially introduced sliding panel menu by introducing a newer concept called Navigation Drawer in which we combine DrawerLayout and NavigationView to achieve the desired output.
How to make hamburger menu fully visible?
SOLUTION:
Use AppCompatActivity instead of Activity and use AppCompat theme to achieve your desired output.
Use NavigationView instead of ListView.
Here is an example of NavigationView:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<!-- Your contents -->
<android.support.design.widget.NavigationView
android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="#menu/my_navigation_items" />
</android.support.v4.widget.DrawerLayout>
Here is a very good tutorial: Android Sliding Menu using Navigation Drawer
Hope this will help~

Hide NavigationDrawer

Im my app i have an Activity called MainActivity it contains a dynamic fragment with id container which i switch depending on state usually my app can be in the state Syncing or Regular now i wan't to add a NavigationDrawerto and i want it to be visible in the ActionBar and on the left only if the MainActivityis not on the Syncingstate since that if the Activity Synching i should not be abble to use the drawer to navigate in my app.
Im using the following activity layout
<!-- A DrawerLayout is intended to be used as the top-level content view using
match_parent for both width and height to consume the full space available. -->
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="pt.ecs.myenergy.MainActivity">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
If you're not building against API 17 or higher, use
android:layout_gravity="left" instead. -->
<!-- The drawer is given a fixed width in dp and extends the full height of
the container. -->
<fragment android:id="#+id/navigation_drawer"
android:layout_width="#dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
android:name="---------.NavigationDrawerFragment"
tools:layout="#layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
The question is for a clever/best way to achieve this. I tought of a few but im not sure which one to use:
Have two xml layouts for the activity, one with the drawer included other without it and use setContentView which would cause for the xml to be inflated not sure if this is a good aproach
Use the merge tag with two childs one the drawer layout (with the container) other with only the container (for the syncing)

I would suggest doing none of those options. They both seem over complicate for no good reason for me.
you should lock the drawer closed using: drawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED)
and if you're also using the an ActionBarDrawerToggle you disable it's indicator with drawerToggle.setDrawerIndicatorEnabled(false)

How to create sliding layout like in Google Drive tablet app or Google+ notifications?

I'd like to create an extra-information view similar to that of the Google Drive app (below) on a tablet. When the info button is clicked, this view slides in from the rightcontaining a layout. Another example would be the Google+ app with its notifications slide-out panel:. The SlidingLayer by 6Wunderkinder almost works, but doesn't fade a semi-black background over the views behind the "drawer" and I haven't found another library that does this.
If anybody has any suggestions/solutions please let me know!
Also, I've already looked at this question and none of the answers suggested there are correct either.

For posterity, here's the answer to this question. As Steve Benett's suggestion led me to discover, the correct way to do this is to use two DrawerLayouts, nested within each other like so:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_navigation_bar"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_sidebar"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:id="#+id/fragment_main_content"
android:name="MainContentFragment"
android:layout_height="match_parent"
android:layout_width="match_parent" />
<fragment
android:id="#+id/fragment_sidebar"
android:name="SidebarFragment"
android:layout_width="300dp"
android:layout_height="match_parent"
android:layout_gravity="end" />
</android.support.v4.widget.DrawerLayout>
<fragment
android:id="#+id/fragment_navigation_bar"
android:name="NavigationFragment"
android:layout_height="match_parent"
android:layout_width="300dp"
android:layout_gravity="start" />
</android.support.v4.widget.DrawerLayout>
The innermost DrawerLayout contains the main content of the Activity, whether it be a fragment or some other layout components. fragment_sidebar is the fragment that will be swiped out from the right. Then, on the top-level DrawerLayout you have the fragment_nagivation_bar which houses the left Drawer's ListView or whatever.
Then, in the Activity Java code you have:
mDrawerLayoutLeft= (DrawerLayout) findViewById(R.id.drawer_navigation_bar);
mDrawerLayoutRight = (DrawerLayout) findViewById(R.id.drawer_sidebar);
mDrawerLayoutLeft.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerLayoutRight.setDrawerShadow(R.drawable.sidebar_shadow, GravityCompat.END);
An optional addition (but recommended, for consistency of UX) is to hide the other Drawer when one is opened, so your screen doesn't consist solely of Drawers.
I hope this has helped somebody!

This is the DrawerLayout. Have a look at the design guide, which illustrates the behavior well.
If you want to use / customize the "semi-black background" use DrawerLayout.setDrawerShadow() with a drawable. Google hands out a set of drawables here. Download the ActionBar Icon Pack and look for the drawable_shadow.9.png.
If you want that the menu appears from the right, set android:layout_gravity="end" as a property in the second child of the layout.

Android NavigationDrawer and ViewPager as its one of fragment

I have created a SherlockFragmentActivity that has three fragments for ViewPager. But now I want to use this Activity in NavigationDrawer but I am confused how to do this. Google+ app has this kind of implementation but I am wondering about how to achieve this.
NavigationDrawer will have following UI elements:
FragmentActivity(contains three fragment as ViewPager)
Second Fragment
Third Fragment
Is this kind of layout possible with Navigation Drawer If yes, how should I do it. If not, what should I do to achieve this kind of navigation in my app.

It is very much possible. You just have to create the right layout file for it.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<RelativeLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- viewpager goes here -->
</RelativeLayout>
<!-- The navigation drawer -->
<LinearLayout android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="start">
<!-- fragment one goes here in drawer -->
<!--- fragment two goes here in drawer-->
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
A DrawerLayout has to have 2 childs, the first is the main content, in your case this will contain the ViewPager and perhaps other stuff. The second child is the Drawer itself.
Use this as the content of your activity.
The rest of the information can be found by using the example on the android developers page here

You can use below libraries to get navigation model similar to your requirement
ActionBarSherlock (github)
nested-fragments (github)
PagerSlidingTabStrip (github)
NavigationDrawer (Android developer site)
Latest Support v4 library
Have a look at my post
Below is screenshot of my sample app Navigation Drawer with Tab Strip Example at github

Android activity from left to right in front

I would like to know what is the type of Android Activity implemented in the image where you can put for example configurations and hide it with a swipe gesture

It is Navigation Drawer a panel that transitions in from the left edge of the screen and displays the app’s main navigation options.
You can find how to Create a Navigation Drawer here
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
The drawer view (the ListView) must specify its horizontal gravity with the android:layout_gravity attribute. To support right-to-left (RTL) languages, specify the value with "start" instead of "left" (so the drawer appears on the right when the layout is RTL).

It looks like Navigation Drawer ,The Navigation Drawer is a panel that transitions in from the left edge of the screen and displays the app’s main navigation options.

That is referred to either as a sliding menu or a navigation drawer.
Google released their own implementation for this last week: http://developer.android.com/training/implementing-navigation/nav-drawer.html
The most popular implementation prior to that was probably this SlidingMenu component.
