Use mouse in a mobile game

Hi I have a game that works fine on my android device It is a tanks game, I can move the tank using a virtual joystick and shoot using a button in a canvas the thing is, I want to make my game works on a VR-Gear and allow me to retate my tank using the sensors of the device, then to move using the scroll wheel of the mouse(yes I want to attach my mouse to my android) that will allow me to move my tank forward and backward, then to use the left click to shoot. so is there a way to do that?
