Android Intent的几种用法总结【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:

  Uri uri = Uri.parse("http://www.google.com");

  Intent it = new Intent(Intent.ACTION_VIEW,uri);

  startActivity(it);

  显示地图:

  Uri uri = Uri.parse("geo:38.899533,-77.036476");

  Intent it = new Intent(Intent.Action_VIEW,uri);

  startActivity(it);

  路径规划:

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

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

  startActivity(it);

  拨打电话:

  调用拨号程序

  Uri uri = Uri.parse("tel:xxxxxx");

  Intent it = new Intent(Intent.ACTION_DIAL, uri);

  startActivity(it);

  Uri uri = Uri.parse("tel.xxxxxx");

  Intent it =new Intent(Intent.ACTION_CALL,uri);

  要使用这个必须在配置文件中加入<uses-permission id="android.permission.CALL_PHONE" />

  发送SMS/MMS

  调用发送短信的程序

  Intent it = new Intent(Intent.ACTION_VIEW);

  it.putExtra("sms_body", "The SMS text");

  it.setType("vnd.android-dir/mms-sms");

  startActivity(it);

  发送短信

  Uri uri = Uri.parse("smsto:0800000123");

  发送彩信

  Uri uri = Uri.parse("content://media/external/images/media/23");

  Intent it = new Intent(Intent.ACTION_SEND);
