I need to build a menu in android that starts as a half circle and once tapped, exposes menu options drawn in an arc around the half circle.
I have experimented with canvas drawing and while it achieves the desired result, there isn't a way to add touch events easily and allow me to animate the menu as i would like.
Is there a library or a better way that will allow me to achieve this.
The background needs to have an overlay and the menu positioned above the overlay to simulate general menu opening as it works on web.
Screenshot of current menu screen:
I need to be able to add touch events to each individual menu item and allow it to open close as well as bring it to the front of the text as even though i have drawn the menu last, the text stays above.
I'm using drawArc, drawCircle and drawText to do it all.
Anything better I can use?
Any help will be appreciated.
It is called a Radial Menu. You can use this widget to get what you are looking for - Radial-Menu-Widget-Android.

I'm looking for a way to produce a button with progress functionality (the button is pressed at the end of the progress...) like in Waze, here in an example (the "Go now" button):
I found this solution:
Create rectangle border progress bar in android
And here is the result of the implementation made there:
But unfortunately this is not good enough (I can't changes the button corner radius to something round and the side progresses moving in a different speed the the top and the bottom progress).
From a check I made the Waze app creates the progress using a canvas and by painting paths on it. How can this be done?
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.
I have 3 main actions on my app. So I want a draggable icon that the user drag on direction of the desired action. Example:
I've found some circular menu libraries on github, but no one seems to have the option to drag the central icon. How can I create this? Maybe a free draggable button with colision test to detect desired action?
in an android application, I need to do the following:
I have a view, that acts like a menu, I can slide it from the bottom-up.
However I want to have 3 states: closed, half-opened and opened.
Please refer to this pic:
The blue section is the Handle, the user will use it to slide up/down or fling...
This is a bit similar to the android 5 notification bar, where you drag down to reveal half the view, then another drag down will reveal the whole view.
I can start implementing it in the onTouch of the blue section but that would require me to handle a lot of cases, especially the ones where the user flings vs slowly drag....
Is there any easier way or library that can help?
Thank you very much
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

btw : this api open source
