Android 用Intent调用系统中经常被用到的组件
调用系统音乐播放器
1 Intent internt = new Intent(Intent.ACTION_VIEW);2 internt.setDataAndType(Uri.parse(item.url), "audio/mp3");3 internt.setComponent(new ComponentName("com.android.music","com.android.music.MediaPlaybackActivity"));4 startActivity(internt);
调用系统视频播放器
1 Intent intent = new Intent(Intent.ACTION_VIEW);2 intent .setDataAndType(Uri.parse("/sdcard/a.mp4"), "video/mp4");3 startActivity(intent );
发送SMS/MMS
调用发送短信的程序
Intent it = "sms_body", "The SMS text""vnd.android-dir/mms-sms"
Uri uri = Uri.parse("smsto:0800000123");
Intent it = new Intent(Intent.ACTION_SENDTO, uri);
it.putExtra("sms_body", "The SMS text");
startActivity(it);
其二是使用SmsManager： 直接发送短信
EditText num=(EditText)findViewById(R.id.num);
EditText content=(EditText)findViewById(R.id.content);
String mobile=num.getText().toString();
String smstext=content.getText().toString(); //获取SmsManager
SmsManager sms=SmsManager.getDefault(); //如果内容大于70字，则拆分为多条
List<String> texts=sms.divideMessage(smstext); //逐条发送短信
for(String text:texts)
{
sms.sendTextMessage(mobile, null, text, null, null);
}
//发送结果提示
Toast.makeText(SendSMS.this, "发送成功", Toast.LENGTH_LONG).show();
关于SmsManager
SDK中的介绍：Manages SMS operations such as sending data, text, and pdu SMS messages. Get this object by calling the static method SmsManager.getDefault().
方法：
public void sendTextMessage (String destinationAddress, String scAddress, String text, PendingIntent sentIntent, PendingIntent deliveryIntent)
destinationAddress： 收件人地址
scAddress： 短信中心号码，null为默认中心号码
sentIntent： 当消息发出时，成功或者失败的信息报告通过PendingIntent来广播。如果该参数为空，则发信程序会被所有位置程序检查一遍，这样会导致发送时间延长。
deliveryIntent： 当消息发送到收件人时，该PendingIntent会被广播。pdu数据在状态报告的extended data ("pdu")中。
如果收件人或者信息为空则抛出 IllegalArgumentException 。
public ArrayList<String> divideMessage (String text)
将大于70字的短信分割为多条。
参数：text the original message. Must not be null.
返回：an ArrayList of strings that, in order, comprise the original message
sendDataMessage 参数与上类似，只是用于发送Data。
sendMultipartTextMessage发送多条短信，发送内容必须是用divideMessage分割好了的。
分享软件
intent=new Intent(Intent.ACTION_SENDTO,Uri.parse("smsto:"+""));
intent.putExtra("sms_body", "我在安卓市场发现了个好东东【通讯录】，快来......下载吧！！安卓市场里面还有很多应用来看看吧！");
startActivity(intent);
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);
拨打电话
调拨打电话界面
Uri telUri = Uri. parse ( "tel:100861" ); returnIt = new Intent(Intent. ACTION_DIAL , telUri);
直接拨打电话
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" />
联系人
进入联系人页面
Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setData(People.CONTENT_URI); startActivity(intent);
打开联系人列表
//第一种Intent i = new Intent();
i.setAction(Intent.ACTION_GET_CONTENT);
i.setType("vnd.android.cursor.item/phone");
startActivityForResult(i, REQUEST_TEXT);
//第二种Uri uri = Uri.parse("content://contacts/people");
Intent it = new Intent(Intent.ACTION_PICK, uri);
startActivityForResult(it, REQUEST_TEXT);
查看指定联系人
Uri personUri = ContentUris.withAppendedId (People.CONTENT_URI, info.id);//info.id联系人ID Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setData(personUri); startActivity(intent);
显示网页:
Uri uri = Uri.parse("http://www.google.com");
Intent it = new Intent(Intent.ACTION_VIEW,uri);
startActivity(it);
web浏览器
Uri uri= Uri. parse ( "http://kuikui.javaeye.com" ); returnIt = new Intent(Intent. ACTION_VIEW , uri );
显示地图:
Uri uri = Uri.parse("geo:38.899533,-77.036476");
Intent it = new Intent(Intent.Action_VIEW,uri);
startActivity(it);
发邮件
returnIt = new Intent(Intent. ACTION_SEND );
String[] tos = { "[email protected]" };
String[] ccs = { "[email protected]" };
returnIt .putExtra(Intent. EXTRA_EMAIL , tos);
returnIt .putExtra(Intent. EXTRA_CC , ccs);
returnIt .putExtra(Intent. EXTRA_TEXT , "body" );
returnIt .putExtra(Intent. EXTRA_SUBJECT , "subject" );
returnIt .setType( "message/rfc882" );//真机上使用这行//returnIt.setType("text/plain");//模拟器请使用这行Intent. createChooser ( returnIt , "Choose Email
Client" );
直接发邮件
Uri smsToUri = Uri. parse ( "smsto://100861" );
returnIt = new Intent(Intent. ACTION_SENDTO ,
smsToUri);
returnIt.putExtra( "sms_body" , "shenrenkui" );
发彩信
Ur i mmsUri = Uri. parse (
"content://media/external/images/media/23" );
returnIt = new Intent(Intent. ACTION_SEND );
returnIt.putExtra( "sms_body" , "shenrenkui" );
returnIt.putExtra(Intent. EXTRA_STREAM , mmsUri);
returnIt.setType( "image/png" )
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);

(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1");
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);

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);
安装
Uri installUri = Uri. fromParts ( "package" , " xxx " ,
null );
returnIt = new Intent(Intent. ACTION_PACKAGE_ADDED ,
installUri);
