基于Mobile SDK V4版固件開發大疆無人機手機端遙控器(3)

第三篇文章準備單獨拿出來寫，因為在大疆為人機的所有功能中，航線規劃的功能最為復雜，也相當的繁瑣，這里需要說仔細一點，可能會將代碼進行多步分解。

1航線規劃

航線打點

在地圖中手動選擇點位選擇完成航線打點；若打點位置錯了可進行點位刪除。

航點設置

可對航線點位進行設置，如飛行高度，速度（慢速:3m/s;中速: 7m/s;高速:10 m/s）、任務結束后操作及航向，點擊[設置]按鈕完成設置。

設置完成后會顯示總距離及飛行總時間。

航線上傳

點擊[上傳]按鈕，進行航線上傳?？梢赃M入本地存儲中選擇航線文件進行上傳，航線文件為 .kml結尾。

航線執行

點擊 [開始]按鈕，則可對航線進行執行。若中途需要暫停也可點擊[暫停]安裝進行暫停操作。

航線管理

按鈕即可進入航線管理界面。

獲取航線

點擊[獲取]按鈕，即可將航線信息展示到地圖界面中。

2主要功能代碼

創建activity_setting_route.xml及SettingRouteActivity文件。
