android - How to show the DrawerLayout when sliding from left to right, no matter where?

Question

background

google has introduced the DrawerLayout, which shows a menu on the left area of the screen when you click on the "up" button of the action bar.

because the library isn't supported yet on actionBarSherlock, there is already a way to overcome it using this project .

it already has variants on many apps: currents, gmail, hangouts, youtube...

the question

on the "currents" app (and in youtube) , when the user slides the (most-left) page from left to right , the DrawerLayout appears, no matter where the finger has started the touch .

how can i achieve the same effect? maybe i should use onInterceptTouchEvent ?

there isn't much documentation and tutorials of what cool things can be done , other than this link (ok and this one too) . they say (in the part of "Give the user a quick peek") that about 20dp on the left is used for this functionality, but i can see that "currents" work with much larger area.

it seems the library is still not quite finished, and so the layout xml file cannot even be shown in the visual UI editor...

EDIT: it seems that the library is open sourced. code is available on :

.../android-sdksourcesandroid-18androidsupportv4widgetDrawerLayout.java
.../android-sdksourcesandroid-18androidsupportv4widgetSlidingPaneLayout.java
.../android-sdksourcesandroid-18androidsupportv4appActionBarDrawerToggle.java

now the question is how to make it work as i've written, so that it would work like on youtube , allowing us to customize how it looks and from where to allow scrolling it.

Answer 1

SlidingMenu is best sliding library I've ever found, It's very good library.
You can set getSlidingMenu().setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN) enabling fling for all screen.
