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

I'm already testing my apps on emulator with targetSdkVersion 29 to test the new swipe back gesture with Android Q.
I'm facing an issue when I have an animation transition between fragments from bottom to top (enter) and from top to bottom (exit).
The swipe back is always from left-to-right but in this case this is not really intuitive.
In the near future, it will be possible to have a swipe back from top-to-bottom ?
At this time, is there a way to solve this kind of problem?
Imho, even if there would be a way to set a custom system swipe back gesture for your app (but which is fortunately not possible), you would:
confuse your users (if you for example block the default swipe back gesture and provide another custom one in your app. You would also have to imitate the system's back animation which I would definitely not recommend to do.)
set a new gesture which is not intuitive, since it's different than the system back gesture and which is also ergonomically not efficient (e.g. try to perform a swipe back from top (border) to-bottom with your thumb; you could also accidentally trigger the status bar.)
Therefore, I don't think that there will be a top-to-bottom swipe back system gesture.
I'm trying to do an Accessibility Service where the purpose it's to create some "layer" between the user when he touches the screen and the tap.
For example : when I touch the screen I when to double tap at this precise position I touch the Screen.
I think, but I'm really open to suggestion, that I will have to create an invisible layout that will cover all the screen where a would be able to activate an onTouchListener to get the position and use my accessibility service to create gesture and transfer the touch behind the layout to click anywhere.
As far I only found a solution for Android 4.1 or less.
I also want to use a kind of cursor, the app Open Sesame do it well and the cursor can go over the navigation bar and interact with.
I also found the open source project Eva facial mouse but they don't perform complex gesture and don't go over the navigation bar.
So my big question is, I am in the right way by wanting to create an invisible layout to detect touch even on the navigation bar and is there someone would help me to enlighten my search in the right direction.
I succeed in putting an overlay layout over the status bar, just add the right Flags to your LayoutParams.
For my case I use: FLAG_FULLSCREEN, FLAG_LAYOUT_IN_SCREEN and FLAG_LAYOUT_NO_LIMITS.
There are some application that disables all the touch inputs, including the touch events that occur on the navigation bar.
Examples are Touch Lock or UnTouch. How one can do that?
By analyzing the second linked app seems that there is a hidden layout that capture the touch events (like an empty onClickListener).
Initially I tried to draw a transparent foreground using the SYSTEM_ALERT_WINDOW permission and by assigning an empty touch listener. However in this way I cannot draw on the navigation bar, so the user can touch the home button and the back button.
Another way that I tried is to launch an Activity with transparent background and in fullscreen mode. In this way I can capture all the events. This works, but obviously this causes other activities to go in pause state.
So my question is, how can one reach the goal? Alternatively is possible to use some root/system commands?
Thanks!
Try this link. If you want to do it on just 1 view then edit out the iteration in the methods given.
I'm trying to make an extra effect to menu that will come down from the top of the screen
I want to make it enter the screen while swiping it from the top and if the user left it, it should continue to the end
this is the figure that demonstrate what I want to do:
I tried to do it with animation but the animation will not go on while swiping and it will go to the end without touching
any other ideas to move the view down with finger ?
Check this out for a sliding Drawer http://developer.android.com/reference/android/widget/SlidingDrawer.html
it sound like you kind of want the same thing as the pulldown menu at the top of all android phones except you want it customized, the link will show you that.
OK
It works for me now
I used SlidingTray.java class from this API
API Website
btw : this api open source
The Android app Thrutu puts a drawer on top of the in call screen which has several functions and only takes up a fraction of the screen. The call control buttons below still are fully functional. Even a transparent activity would not allow this behaviour. Any idea on how to implement this?
The trick to making the underlying buttons work is to implement the UI using a Service rather than an Activity, make the Window you add (using WindowManager.addView) one of the higher-priority types (e.g. TYPE_PHONE), then use FLAG_NOT_TOUCH_MODAL.
I think you need android.permission.SYSTEM_ALERT_WINDOW.
Take a look at How to display a fullscreen TYPE_SYSTEM_ALERT window? and in particular Creating a system overlay where the home buttons still work?
