Embodiment 1

[0017] Such as figure 1 As shown, the present invention provides a touch control method for a dual-screen display device, comprising the following steps:

[0018] Step 1. The touch screen auxiliary service divides the touch screen area located in the range of the main display screen into the main touch area according to the resolution range of the main display screen and the auxiliary display screen, and records the coordinate range of the main touch area through the system attributes. The area is divided into sub-touch areas, and the coordinate range of the sub-touch area is recorded through system properties.

[0019] Step 2. Because Android distributes touch events based on the display ID information of touch events, it decides which display screen application to distribute touch events to. Normally, each display screen on an Android device has a unique display ID. ID, the display ID of the primary display is 0, and the display ID of the secondary display is non-zero. The...

Abstract

The invention discloses a touch control method of double-screen display equipment, which comprises the following steps of: initializing auxiliary service of a touch screen, and dividing a main touch area and an auxiliary touch area; detecting a touch event, judging whether the touch event occurs in the main touch area or the auxiliary touch area, and marking the touch event as display ID information corresponding to the display screen; zooming the touch event coordinates according to the width-to-height ratio of the resolution of the main / auxiliary touch area and the resolution of the main / auxiliary display screen and converting into touch event coordinates on the corresponding display screen; and distributing the event to the application program on the corresponding display screen by thethe event distribution service according to the display ID. According to the method, touch control over the main display screen and the auxiliary display screen is achieved only through one touch screen, and therefore cost is saved.

Description

technical field [0001] The present invention relates to the technical field of touch control methods, in particular to a touch control method for a dual-screen display device. Background technique [0002] With the development of display devices and touch technology, electronic devices are not limited to one display screen, and the application of dual-screen and dual-touch devices is becoming more and more extensive, especially the dual-screen and dual-touch advertising machine equipment in major Public places with large traffic such as shopping malls and residential areas are widely used. However, in the current dual-screen dual-touch device, the main display screen and the auxiliary display screen are usually connected to a touch screen, the main touch screen corresponds to the main display screen, and the auxiliary touch screen corresponds to the auxiliary display screen. When the touch event occurs on the main touch screen, the touch event is distributed to the correspo...
