Desejo desenhar um círculo sempre que o usuário tocar em uma visualização personalizada e com base nas alterações de cor do círculo de contagem de toque.

Single Tap : YELLOW CIRCLE
Double Tap : GREEN CIRCLE
Triple Tap : RED COLOR

O problema é que, eu fiz uma visualização personalizada que contará o evento de toque com base no tempo, mas em algum momento ele perderá o primeiro toque. que causam o problema em vista.

O código a seguir mostra todo o meu esforço para criar uma exibição personalizada acima.
