Abstract: A slide unlocking method for a touchscreen device under a screen locking state is provided. The method includes steps of: sampling a track generated by the sliding of a user's finger on a touchscreen, and sequentially acquiring a plurality of sampling points; acquiring a first sampling point and a last sampling point of the track, and calculating a transverse sliding distance and a longitudinal sliding distance of the finger on the touchscreen; and unlocking the touchscreen when the transverse sliding distance is greater than or equal to a first preset distance and the longitudinal sliding distance is less than or equal to a second preset distance; otherwise, keeping the screen in the lock state. In this way, the present invention increases the degrees of freedom of a user's operation, so that a user can conveniently perform unlocking in a special usage scenario.

Abstract: A mobile terminal and an incoming call processing method thereof are disclosed. The method comprises the following steps: controlling the incoming call controller to be shown on a pre-designated position of a screen when the mobile terminal is in a screen-locked state and the incoming call arrives; detecting by the mobile terminal whether the incoming call controller is dragged for a predetermined distance, and controlling an Answer and Decline selection interface to be shown on the screen when the incoming call controller is dragged for the predetermined distance; receiving by the mobile terminal an operating instruction from a user through the Answer and Decline selection interface and entering an in-call interface or declining the incoming call.
