首先输入Command查看你的input配置~

adb shell dumpsys input

下面给出我设备输出的一部分!!

INPUT MANAGER (dumpsys input)

      ConfigurationFile: /system/usr/idc/Fts-touchscreen.idc
      HaveKeyboardLayoutOverlay: false 

从上面可以看到"4: Fts-touchscreen",这货就是我的触摸屏啦(??? )
我们看下他的配置文件,就是这货"ConfigurationFile: /system/usr/idc/Fts-touchscreen.idc"
提示下,如果配置文件那显示为空的话,你就直接用你触摸屏的名字就行了,比如我的就是这样!!!
然后我们把官方包里面的/system/usr/idc/Fts-touchscreen.idc给替换过去就搞定了
