Abstract: Embodiments of the present invention provide a method and an apparatus for reporting a touch event, and a mobile terminal. The method for reporting a touch event includes: receiving touch data collected by an inductance capacitance touch screen; and encapsulating the touch data collected by the inductance capacitance touch screen into a touch event corresponding to a mutual capacitive touch screen and reporting the touch event to an application program. With the present invention, the touch data collected by the inductance capacitance touch screen is encapsulated into the touch event corresponding to the mutual capacitive touch screen and the touch event is reported, thereby solving the problem that an application program of an earlier version cannot be used when a mobile terminal can receive only the touch data collected by the inductance capacitance touch screen.
