[android adb shell] 怎么解锁图案锁屏(pattern lock)的手机？

所谓的防水手机由于冲洗屏幕进水而触摸失灵了，幸好adb是打开的，还能用usb连上，然而问题来了，我加了图案锁屏，虽然adb shell能进，但死活操作不了啊。。。

首先，要确定触摸事件的设备，我的手机是event2

其次，分辨率肯定得搞清楚，可参考 https://blog.csdn.net/u011967006/article/details/53760678 获取分辨率。

stackoverflow上找到如下资料：

For touch events only 2 event types are used:
EV_ABS (3)
EV_SYN (0)

Touching the display (in case of Type A protocol) will result in an input report (sequence of input events) containing the following event codes:
ABS_MT_TRACKING_ID (57) - ID of the touch (important for multi-touch reports)
ABS_MT_POSITION_X (53) - x coordinate of the touch
ABS_MT_POSITION_Y (54) - y coordinate of the touch
ABS_MT_TOUCH_MAJOR (48) - basically width of your finger tip in pixels
ABS_MT_PRESSURE (58) - pressure of the touch
SYN_MT_REPORT (2) - end of separate touch data
SYN_REPORT (0) - end of report

然后就是不停尝试了，不同手机貌似不太一致。

如下是个图案 “Z”，最后居然一口气画了出来。一开始还以为中间断线没法完成了。
