I have here listofpatients in a listview. This items are populated from MySql database. Now when i long press the item it will show contextmenu with edit and delete. In edit I want to pass it in EditPatient activity and those values will be passed to Edit page by getting the id(id from database) of an item. For example i need to edit PatientJay with the UID = 34. That UID should be passed to the editpatient activity. I don't know how to this.
Here's the code
