[Android] Intent 用法大公開 (2010-02-24 17:30)
分类: Android
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。
顯示網頁
- Uri uri = Uri.parse("http://google.com");
- Intent it = new Intent(Intent.ACTION_VIEW, uri);
- startActivity(it);
顯示地圖
- Uri uri = Uri.parse("geo:38.899533,-77.036476");
- Intent it = new Intent(Intent.ACTION_VIEW, uri);
- startActivity(it);
- //其他 geo URI 範例
- //geo:latitude,longitude
- //geo:latitude,longitude?z=zoom
- //geo:0,0?q=my+street+address
- //geo:0,0?q=business+near+city
- //google.streetview:cbll=lat,lng&cbp=1,yaw,,pitch,zoom&mz=mapZoom

Simple:
Install from native apk
Intent promptInstall =newIntent(Intent.ACTION_VIEW)
.setData(Uri.parse("file:///path/to/your.apk"))
.setType("application/vnd.android.package-archive";
startActivity(promptInstall);
Install from Market
Intent goToMarket =newIntent(Intent.ACTION_VIEW)
.setData(Uri.parse("market://details?id=com.package.name"));
startActivity(goToMarket);
