android 手機紅外遙控器實現

 通過連續幾天的編制，安卓手機代碼終於完成了，目前已經將我宿舍，家裏，集控室的紅外遙控電氣設備無缺的遙控了，另外還遙控了個人D7000相機，不錯終於完工了。
代碼分爲二類：
各類電視、相機、等等遙控編碼最簡單，只要將按鍵的編碼複製下來，直接變成手機發射碼就能夠了。（這種編碼單個按鍵只發射單個信息）
最難的是空調編碼，因爲空調編碼是將單個按鍵要發射全部控制信息，如增長一度溫度，同時要將控制模式、溫度、風量等等全部信息一同發射出去，還有檢驗碼，經過長時間實驗，若是像通常模仿遙控器的設備（例如萬能遙控器）編碼是將各類組合分別保存起來，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，並且要再程序中變成組合再變成安卓發射碼，比較麻煩。
通過摸索     格力遙控器編碼規則以下（前面的資料是網上搜集來的，這裏是本身總結的）：
