How to use Intent to send an email, SMS, open a web browser, show map, etc.?
Intent 應該算是 Andorid 中特有的東西。你可以在 Intent 中,指定要應用程式執行的動作 (view, edit, dial),以及應用程式執行該動作時,所需要的資料。都指定好後,只要透過 startActivity(),Android 系統會自動尋找,最符合你指定要求的應用程式,並喚起執行該應用程式。
不過,這部份的文件還不是很完整。Reference of Available Intents 有列一些。底下是我收集的一些用法,分享出來給有需要的你。有些還沒有實際驗證過,如果發現有錯誤,或有新的用法,也請告訴我。
