Android：SlidingDrawer就像Android主窗口中的那个一样

Question

I implemented a SlidingDrawer in my app and everything works fine so far.

Then I made an invisible handle, just like the one in the Android main window.

Now I want, that it is possible to grab the handle (and make it visible) just by moving the finger over the handle. I mean the same behaviour like the one in the Android main window.

But i don´t know how to mange that. (At the moment it only works when you tap at the handle, and not if you tap somewhere else and move the finger above the handle)

Answer 1

Sounds like a bad idea. There will be no way to distinquish between the system's drawer and your app's drawer.

Answer 2

You want to detect a swipe motion that starts on the top bezel.

You want to use MotionEvent's getEdgeFlags() to detect whether a swipe gesture starts on the bezel.
