Question

我正在Mac OS Mojave上使用android oreo。
我试图在应用程序中获取输入文本，然后遇到“ cdfinger_input”，它似乎与我在手机上键入的文本有关。我不知道我是否正确，因为我无法在互联网上找到有关它的任何信息。

这是我使用终端及其输出在adb shell中键入的内容。

我只想了解“ cdfinger_input”代表的事件类型。

Answer 1

cdfinger_input只是一个设备名称。它不代表任何东西。它只是设备制造商任意选择的字符串。如果我猜到了，我会说所涉及的设备是指纹传感器。

但是您不必猜测，而应该使用getevent -il /dev/input/event2命令来查看设备支持的所有事件的实际列表。

cdfinger_input在adb shell getevent中代表什么类型的事件
