You can do it programmatically with your own logic. Like you can set a listener for your NavigationDrawer and detect position of the drawer, Here is the helping link.

How can I open a navigation drawer with a swipe from the left gesture?

I created a navigation drawer but I don't want to use the ActionBar with the hamburger button, I would like to be able to open the navigation drawer with a swiping gesture from the left to the right in every activity.
I also don't understand very well the use of Fragments.
By the way, to create my Navigation drawer I used this youtube video: Video
Thanks.

You can achieve this by hiding the hamburger button. Set your toolbar navigation icon to null.
toolbar.setNavigationIcon(null);

Use navigation drawer menu in child Activity

I use sliding drawer menu in my android project and
I use one drawer menu for all of myActivies
I want in root Activity when click on actionbar`s icon the drawer menu is open!
and in childs Activities when click on actionbar's icon go to parent Activity
like google play or gmail and ...
how I can do this?!

Implement the navigation as usual (with drawertoggle and everything), then call
_toggle.setDrawerIndicatorEnabled(false);
It will hide the drawer icon (the three vertical lines) and display the up caret. The up icon click event will not be handle by the drawer and will finish the activity (if you do so in the OnOptionsItemSelected).

yup, you can use Navigation drawer in the layout and as well as in the java code.
