Android 手機紅外遙控器實現（轉）

源：http://www.cnblogs.com/xiaochao1234/p/3615467.html

　　經過連續幾天的編制，安卓手機代碼終於完成了，目前已經將我宿舍，家里，集控室的紅外遙控電氣設備完好的遙控了，另外還遙控了我的D7000相機，不錯終於完工了。 代碼分為二類： 各種電視、相機、等等遙控編碼最簡單，只要將按鍵的編碼復制下來，直接變成手機發射碼就可以了。（這種編碼單個按鍵只發射單個信息） 最難的是空調編碼，由於空調編碼是將單個按鍵要發射所有控制信息，如增加一度溫度，同時要將控制模式、溫度、風量等等所有信息一同發射出去，還有檢驗碼，通過長時間實驗，如果像一般模仿遙控器的設備（例如萬能遙控器）編碼是將各種組合分別保存起來，這要就很長，也很麻煩，但用第一種方法實現起來就很容易。第二種方法主要是找規律比較麻煩，而且要再程序中變成組合再變成安卓發射碼，比較麻煩。 經過摸索     格力遙控器編碼規則如下（前面的資料是網上搜集來的，這里是自己總結的）：
