Intent的几种用法

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。

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);

 

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);

 

路径规划:

1.        Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");

2.        Intent it = new Intent(Intent.ACTION_VIEW,URI);

3.        startActivity(it);

 

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); 

 

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 android:name="android.permission.CALL_PHONE" />

 

 

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);

4.        it.setType("text/plain");  

5.        startActivity(Intent.createChooser(it, "Choose Email Client")); 

 

1.        Intent it=new Intent(Intent.ACTION_SEND);    

2.        String[] tos={"[e-mail]"};
