touch.deviceType 定义:touch.deviceType = touchScreen | touchPad | pointer | default 指定触摸设备类型。 如果值为touchScreen,则触摸设备是与显示屏相关联的触摸屏。 如果值为touchPad,则触摸设备是不与显示屏相关联的触摸板。 如果值为pointer,则触摸设备是不与显示屏相关联的触摸板,并且其动作用于间接多点触控...

Atouch screendevice is used for direct manipulation of objects on the screen. Since the user is directly touching the screen, the system does not require any additional affordances to indicate the objects being manipulated.

device->classes |= CLASS_TOUCHSCREEN; //LOGI("It is a single-touch screen!"); } …… } 我们知道,在触摸屏驱动中,通常在probe函数中会调用input_set_abs_params给设备的input_dev结构体初始化,这些input_dev的参数会在Android的EventHub.cpp中被读取。如上可知,如果我们的触摸屏想被当成多点屏被...
