Android開發-藍牙遙控器（字符串形式發送）-應用例程

一、例程簡介

    1、應用界面圖（主界面、設置界面）

 

    2、實現功能：

        （1）打開應用，顯示主界面，檢測藍牙功能是否打開，否則詢問打開；

        （2）打開藍牙功能後，點擊“連接設備：”下的按鈕選擇已匹配的藍牙設備進行連接；

        （3）若藍牙設備未匹配，可點擊旁邊的 […] 按鈕打開系統藍牙設置界面，進行藍牙匹配；

        （4）點擊中央的上、下、左、右和中間按鈕，可發送不同的藍牙字符串消息；

        （5）藍牙消息內容可通過點擊 [設置] 按鈕在設置界面中設置，設置的數據重啓應用後依然有效；

        （6）其中，中間按鈕具有長按按下、長按釋放和點擊三種不同效果；

        （7）本應用還附帶來電監聽功能，有來電時，會自動發送藍牙消息；

        （8）點擊 [退出] 按鈕，關閉藍牙連接，並且關閉安卓設備藍牙功能。
