Capturing images

Hello. I'm creating an application in which I use an imageview, an editText and a calendarview, the imgageview and the editText are for customization, so that the user can select the image he wants and leave the message he wants, leaving the calendar personalized.    So far beauty, but I wanted to know if you have how after the user selects the image and fills the editText, if it has how to save that screen image, so that it can be shared.    Does anyone know if there is a workaround for this?
