1+1 I have same problem dude.. see [my Question](http://stackoverflow.com/questions/12577200/radial-menu-android-with-button-click) – MAC Sep 25 '12 at 08:45

3I don't have to implement something like that, but I am interested in the answer. I would look in the direction of the animation API if I had to guess. – Teovald Sep 25 '12 at 08:51

I recently created this circular menu to add up in my recent project. It looks like
What you need is to create a new View and draw this view, check for the user inputs (where he is touching), design a feedback mechanism, for example, in my view, if user touches any of the 5 arcs, background color changes to skyblue. Here is my code for View Class.

I know this isn't the best way and not professional too. I created this menu as per need. Its not scale able in a way until you change the angle calculations.

Yes. Sure. I would love to. Just being curious, which part of the code I need to put down here ? Is it touch handling part (I nearly banged my head against wall for how to decide where user touched ?), or is it the initialization part ? – Gaurav May 03 '13 at 18:35
-
Actually I need the codes which can be draw the menu ... and click listener too.. – Pankaj Kumar May 06 '13 at 04:48

Thanks for the code. Helped a lot. Could you tell us how to make it a full circle 360? – DanKodi Sep 17 '13 at 06:16
-
@DanKodi: As you can see in function, onDraw(), there are variables named initial and finalangle, change it to 0 and 360, you will get a full circle. Please keep in mind, you would also have to change the y co-ordinate of center too in order to view the full circle. – Gaurav Sep 19 '13 at 07:32

1hay, @hasH working fine but some issue i want large menu circle can you help me where i need to change ... thank you – Sagar Devani Dec 24 '14 at 07:19

Change setMeasuredDimension(d, d) to the size you want. But you may run into overlapping plus touch feedback issues. – Gaurav Dec 24 '14 at 09:00

its really nice but need some customization like can we do the center "minus" view as like navigation drawer icon (three bars) and want to put this in right side center vertical, if i click on bars the arcs will pop out again click it will hide. – Devendra Singh May 06 '15 at 10:38
