First of all, the idea of first click Dial to enter an interface, select confirm, call the system calls directly, and then determine the status of the call, if it is dialed in the State with the window manager to write a block occlusion if not dialed state will be removed, remove the completion of the current activity, in O Perform a find call record in Nactivityforresult to delete. Okay, start on the code.
Main interface Mainactivity.class
Dial-up interface Mian2.class don't mind the names.
