voy a desarrollar la aplicación y quiero crear el menú como Catch notes AppCatch Android notas de aplicación Al igual Círculo Menú
Screen Shoot
cualquiera que sé cómo puedo poner en práctica este o si hay alguna biblioteca disponible para ello. Por favor hagamelo saber.
Gracias
recientemente he creado este menú circular a sumar en mi reciente proyecto. Parece que 
Lo que necesita es crear una nueva vista y sacar este punto de vista, la verificación de las entradas de usuario (en la que está tocando), el diseño de un mecanismo de retroalimentación, por ejemplo, en mi opinión, si usuario toca cualquiera de los 5 arcos, el color de fondo cambia a azul celeste. Aquí está mi código para View Class.
[EDITAR]: Esta vez estoy publicando todo mi código para la vista. Espero que te pueda ayudar.

Sé que esta no es la mejor manera y tampoco profesional. Creé este menú según las necesidades. No es escalable de ninguna manera hasta que cambie los cálculos de los ángulos.
Puedes publicar el código más –
Sí. Por supuesto. Me encantaría. Siendo curioso, ¿qué parte del código necesito poner aquí? ¿Es la parte de manejo táctil (casi me golpeé la cabeza contra la pared cómo decidir dónde tocó el usuario?), ¿O es la parte de inicialización? – Paras
En realidad necesito los códigos que pueden dibujar el menú ... y también hago clic en el oyente ... –
+1 Tengo el mismo problema amigo ... vea [mi pregunta] (http://stackoverflow.com/questions/12577200/radial-menu-android-with-button-click) – MAC
No tengo que implementar algo así, pero estoy interesado en la respuesta. Miraría en la dirección de la API de animación si tuviera que adivinar. – Teovald
