how add edittext value in database pls body me!!!!!!!!

you need create method in databasehelper class takes in 4 strings , adds them database.

then in onclick() method in medical activity class can string values 4 edittext fields , call method these values.

i recommend going through notepad tutorial. should provide example of want do.
