Intent的几种用法(转)

Intent应该算是Android中特有的东西。你可以在Intent中指定程序要执行的动作（比如：view,edit,dial），以及程序执行到该动作时所需要的资料。都指定好后，只要调用startActivity()，Android系统会自动寻找最符合你指定要求的应用程序，并执行该程序。

下面列出几种Intent的用法
显示网页:

1. Uri uri = Uri.parse("http://www.google.com");
2. Intent it  = new Intent(Intent.ACTION_VIEW,uri);
3. startActivity(it);

复制代码

显示地图:

1. Uri uri = Uri.parse("geo:38.899533,-77.036476");
2. Intent it = new Intent(Intent.Action_VIEW,uri);
3. startActivity(it);

复制代码

路径规划:

1. Uri uri = Uri.parse("http://maps.google.com/maps?f=dsaddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");
2. Intent it = new Intent(Intent.ACTION_VIEW,URI);
3. startActivity(it);

复制代码

拨打电话:
调用拨号程序

1. Uri uri = Uri.parse("tel:xxxxxx");
2. Intent it = new Intent(Intent.ACTION_DIAL, uri);  
3. startActivity(it);  

复制代码

1. Uri uri = Uri.parse("tel.xxxxxx");
2. Intent it =new Intent(Intent.ACTION_CALL,uri);
3. 要使用这个必须在配置文件中加入<uses-permission id="android.permission.CALL_PHONE" />

复制代码

发送SMS/MMS
调用发送短信的程序

1. Intent it = new Intent(Intent.ACTION_VIEW);   
2. it.putExtra("sms_body", "The SMS text");   
3. it.setType("vnd.android-dir/mms-sms");   
4. startActivity(it);  

复制代码

4. startActivity(it);  

复制代码

4. it.setType("text/plain");   
5. startActivity(Intent.createChooser(it, "Choose Email Client"));  

复制代码

1. Intent it=new Intent(Intent.ACTION_SEND);     
2. String[] tos={"me@abc.com"};     
3. String[] ccs={"you@abc.com"};     
4. it.putExtra(Intent.EXTRA_EMAIL, tos);

3. Intent it = new Intent(Intent.ACTION_VIEW, uri);  
4. startActivity(it);  
5. //where pkg_name is the full package path for an application  
6. //显示指定应用的详细页面（这个好像不支持了，找不到app_id）
7. Uri uri = Uri.parse("market://details?id=app_id");  
8. Intent it = new Intent(Intent.ACTION_VIEW, uri);  
9. startActivity(it);  
10. //where app_id is the application ID, find the ID  
11. //by clicking on your application on Market home  
12. //page, and notice the ID from the address bar

复制代码
using the following code snippet for searching through Google

How to use Intent to send an email, SMS, open a web browser, show map, etc.?

Activity 物件把Intent物件传送给Android,向Android诉说意图，由Android去物色及启动适当的Activity.除了Activity外，我们还可以用Intent物件来启动BoradcastReceiver和Service两个物件。

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);

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

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
