Android 4.0.3上的USB触摸屏->无法选择(只能移动指针) [英] USB touchscreen on Android 4.0.3 -> not possible to select (only moving the pointer)

问题描述

早上好.

我购买了集成了电阻式触摸屏的LCD嵌入式显示器. TS可通过USB连接.

I bought a LCD embedded display with a resistive touch screen integrated. The TS is interfaceable via USB.

我已将其连接到运行Android 4.0.3的设备，并且触摸被正确识别为外部HID. 问题:点击(按下)不被识别为选择/确认...发生的唯一事情是，当我点击屏幕时，是在与手指的坐标一致的情况下移动指针(箭头).没有左键单击的鼠标HID

I have connected it to a device running Android 4.0.3 and the touch is correctly recognized as externale HID. PROBLEM: the tapping (pressing) is not recognized as selection/confirmation...the only thing that happens, when I tap the screen, is to move the pointer(arrow) in corrispondance of the coordinated of my finger..like I moved a mouse HID without left left clicking

我不可能滚动或选择某些内容->对我来说是一团糟:(

It's not possible for me to scroll or to select something --> big mess for me :(

请记住，我还有另一台带有集成USB TS的液晶显示器，该液晶显示器正常工作.我可以选择图标以防万一我点击它们，并且我可以滚动窗口等->就像鼠标始终单击鼠标左键->对我来说确定！！

Please keep in mind that I have another LCD with integrated USB TS that works proprerly. I can select icons in case I tap on them and I can scroll the windows etc -> exactely like a mouse with left button always clicked -> OK for me!!!

也许这是司机的事，但我没有具体想法.

Maybe it is a matter of drivers but I have no specific ideas.

P.s.我没有该设备的特定驱动程序.

P.s. I have no specific drivers for the device.

有人建议吗?请帮助我:)

Any suggestion guys? Please help me :)

提前谢谢！！！！

推荐答案

您需要为设备创建 .idc 配置文件.

You need to create .idc configuration file for your device.

此处描述的过程 http://source.android.com/tech/input/input-device-configuration-files.html

例如，如果您的设备名为XYZ触摸屏，则在/system/usr/idc/中创建文件 XYZ_Touchscreen.idc 内容如下:

For example if you have device with name XYZ Touchscreen, create file XYZ_Touchscreen.idc in /system/usr/idc/ with content like this:

# Basic Parameters
touch.deviceType = touchScreen
touch.orientationAware = 1
touch.gestureMode = default
device.external = 1
touch.usingJitterFilter = 1
