Android Intent的几种用法全面总结

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：

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);

Uri uri = Uri.parse("mailto:[e-mail]");
Intent it = new Intent(Intent.ACTION_SENDTO, uri);
startActivity(it);

Intent it = new Intent(Intent.ACTION_SEND);

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={"[e-mail]"};    
String[] ccs={"[e-mail]"};    
it.putExtra(Intent.EXTRA_EMAIL, tos);    
it.putExtra(Intent.EXTRA_CC, ccs);

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);

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

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