  • 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");

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

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

      startActivity(it);

      发送彩信

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

      Intent it = new Intent(Intent.ACTION_SEND);

      it.putExtra("sms_body", "some text");

      it.putExtra(Intent.EXTRA_STREAM, uri);

      it.setType("image/png");

      startActivity(it);

      发送Email

      Uri uri = Uri.parse("mailto:xxx@abc.com");

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

      startActivity(it);

      Intent it = new Intent(Intent.ACTION_SEND);

      it.putExtra(Intent.EXTRA_EMAIL, "me@abc.com");

      it.putExtra(Intent.EXTRA_TEXT, "The email body text");

      it.setType("text/plain");

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

      Intent it=new Intent(Intent.ACTION_SEND);

      String[] tos={"me@abc.com"};

      String[] ccs={"you@abc.com"};

      it.putExtra(Intent.EXTRA_EMAIL, tos);

      it.putExtra(Intent.EXTRA_CC, ccs);

      it.putExtra(Intent.EXTRA_TEXT, "The email body text");

      it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");

      it.setType("message/rfc822");

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

      添加附件

      Intent it = new Intent(Intent.ACTION_SEND);

      it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");

      it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/mysong.mp3");

      sendIntent.setType("audio/mp3");

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

      播放多媒体

      Intent it = new Intent(Intent.ACTION_VIEW);

      Uri uri = Uri.parse("file:///sdcard/song.mp3");

      it.setDataAndType(uri, "audio/mp3");

      startActivity(it);

      Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1");

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

      startActivity(it);

      Uninstall 程序

      Uri uri = Uri.fromParts("package", strPackageName, null);

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

      startActivity(it);
