本文講的是通過使用代碼，可以控制手機的屏幕和物理按鍵，也就是說不只是在某壹個APP裏去操作，而是整個手機系統。
更多問題解決辦法請參考android學習手冊,例子、源碼、文檔全部搞定，采用androidstudo的目錄結構，360手機助手中下載。下面是截圖。
getevent/sendevent
getevent&sendevent 是Android系統下的壹個工具，可以模擬多種按鍵和觸屏操作，產生的是raw event，raw event經過event hub處理產生最終的gesture事件。getevent用於獲取當前系統input設備的壹些參數和實時事件的數據；sendevent用於發送input事件，這倆命令的作用就是相當於解放了手，可以通過命令直接調用Linux底層來控制手機，工具的源碼位於Android SDK的system/core/toolbox下（sendevent.c getevent.c）。
getevent
用法說明：
[plain] view plain copy print?
#?getevent?-h
Usage:?getevent?[-t]?[-n]?[-s?switchmask]?[-S]?[-v?[mask]]?[-p]?[-q]?[-c?count]?[-r]?[device]
-t:?show?time?stamps
-n:?don't?print?newlines
-s:?print?switch?states?for?given?bits
-S:?print?all?switch?states
-v:?verbosity?mask?(errs=1,?dev=2,?name=4,?info=8,?vers=16,?pos.?events=32)
-p:?show?possible?events?(errs,?dev,?name,?pos.?events)
-q:?quiet?(clear?verbosity?mask)
-c:?print?given?number?of?events?then?exit
-r:?print?rate?events?are?received
# getevent -h
Usage: getevent [-t] [-n] [-s switchmask] [-S] [-v [mask]] [-p] [-q] [-c count] [-r] [device]
-t: show time stamps
-n: don't print newlines
-s: print switch states for given bits
-S: print all switch states
-v: verbosity mask (errs=1, dev=2, name=4, info=8, vers=16, pos. events=32)
-p: show possible events (errs, dev, name, pos. events)
-q: quiet (clear verbosity mask)
-c: print given number of events then exit
-r: print rate events are received
其中?[-t]?參數顯示事件的時間戳，[-n]?取消事件顯示時的換行符，[-s switchmask]?得到指定位的開關狀態，[-S]?得到所有開關的狀態，[-v [mask]]?根據mask的值顯示相關信息，後面詳細介紹mask的使用方法，[-p]?顯示每個設備支持的事件類型和編碼，[-q]?只顯示事件數據，[-c count]?只顯示count次事件的數據，[-r]?顯示事件接收頻率。

可以看到 [-p] 參數顯示出來當前系統存在的所有input設備，並且把每個設備支持的事件類型以及編碼都列舉了出來。
每壹個device相當於手機所支持的input設備，每個device裏面的events下：KEY(0001) 、ABS(0003)、SYN(0000)等表示該設備所支持的事件類型：EV_SYN?[0000] (同步事件)，EV_KEY?[0001] (按鍵事件)，EV_ABS?[0003] (絕對值事件)
舉例event0中的KEY類型：
[java] view plain copy print?
KEY?(0001):?0066008b009e00d9
KEY?(0001):?0066008b009e00d9
表示sec_touchscreen支持的按鍵編碼有：KEY_HOME?[0066] (HOME鍵)，KEY_MENU?[008b] (MENU鍵)
KEY_BACK?[009e] (BACK鍵)，KEY_SEARCH?[00d9] (SEARCH鍵)
舉例event0中的ABS類型：
