[android adb shell] 怎麼解鎖圖案鎖屏(pattern lock)的手機？
所謂的防水手機由於沖洗螢幕進水而觸控失靈了，幸好adb是開啟的，還能用usb連上，然而問題來了，我加了圖案鎖屏，雖然adb shell能進，但死活操作不了啊。。。
首先，要確定觸控事件的裝置，我的手機是event2
其次，解析度肯定得搞清楚，可參考 https://blog.csdn.net/u011967006/article/details/53760678 獲取解析度。
stackoverflow上找到如下資料：
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
然後就是不停嘗試了，不同手機貌似不太一致。
如下是個圖案 “Z”，最後居然一口氣畫了出來。一開始還以為中間斷線沒法完成了。
