Windows 8.1 Update 1 is nearing completion and is still in beta, but we can also see some upcoming changes through screenshots.

Android provides support for two gesture behaviors:1, for the first gesture behavior, Android provides gesture detection, and for gesture detection provides a corresponding listener.2, for the second gesture behavior, Android allows developers to add gestures, and provide the appropriate API to identify user gestures.Gesturedetector.ongesturelistener is a listener that is responsible for providing the user with the gesture behavior.Boolean Ondown (Motionevent e): Triggers the method when the tou

Press (Ondown): Just the moment the finger touches the touch screen, it is the touch of the moment.
Throw (onfling): The finger moves quickly on the touchscreen and releases the action.

I2C pin. the I2C of the development board itself has a K pull-up resistor, so no external pull-up resistor is needed.
3) connect the gpio_9 of the development board to the int port of the chip to control interruption.
4) A gpio is required to control the reset of the chip, but the gpio foot of the touch screen interface of the Development Board has only one gpio_9. Therefore, find another gpio foot to control the reset.
The connection method is as follows:
1 vcc33 => 3.3 V
2 Gnd => ground

Touch System Events OverviewTouch events are a series of events on a touchscreen device that occur when a user touches the screen and a series of actions.Contains Touchstart, Touchmove, touchend events.Program IdeasWe focus on the abstract object of the event, such as the Touchmove event that occurs when the finger moves over the touchscreen, and we go to find the properties related to this event, depending

If a device can accept a touch event, and the user interacts with it by touching the control or giving it focus, the control may not always be hi
