Android 用Intent調用系統中經常被用到的組件

調用系統音樂播放器

Intent internt = new Intent(Intent.ACTION_VIEW);
internt.setDataAndType(Uri.parse(item.url), "audio/mp3");
internt.setComponent(new ComponentName("com.android.music","com.android.music.MediaPlaybackActivity"));
startActivity(internt);

調用系統視頻播放器

Intent intent = new Intent(Intent.ACTION_VIEW);
intent .setDataAndType(Uri.parse("/sdcard/a.mp4"), "video/mp4");
startActivity(intent );

 

發送SMS/MMS
調用發送短信的程序

Intent it = new Intent(Intent.ACTION_VIEW);
it.putExtra("sms_body", "The SMS text");
it.setType("vnd.android-dir/mms-sms");
startActivity(it);

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： 直接發送短信 

EditText num=(EditText)findViewById(R.id.num);

                EditText content=(EditText)findViewById(R.id.content);

                String mobile=num.getText().toString();

                String smstext=content.getText().toString();

                //獲取SmsManager

                SmsManager sms=SmsManager.getDefault();

                //如果內容大於70字，則拆分為多條

                List<String> texts=sms.divideMessage(smstext);

                //逐條發送短信

                for(String text:texts)

                {

                    sms.sendTextMessage(mobile, null, text, null, null);

                }                

                //發送結果提示

                Toast.makeText(SendSMS.this, "發送成功", Toast.LENGTH_LONG).show();

 

關於SmsManager

SDK中的介紹：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： 短信中心號碼，null為默認中心號碼

sentIntent： 當消息發出時，成功或者失敗的信息報告通過PendingIntent來廣播。如果該參數為空，則發信程序會被所有位置程序檢查一遍，這樣會導致發送時間延長。

deliveryIntent： 當消息發送到收件人時，該PendingIntent會被廣播。pdu數據在狀態報告的extended data ("pdu")中。

如果收件人或者信息為空則拋出 IllegalArgumentException 。

public ArrayList<String> divideMessage (String text)

將大於70字的短信分割為多條。

參數：text    the original message. Must not be null.

返回：an ArrayList of strings that, in order, comprise the original message

sendDataMessage 參數與上類似，只是用於發送Data。

sendMultipartTextMessage發送多條短信，發送內容必須是用divideMessage分割好了的。

 分享軟件

intent=new Intent(Intent.ACTION_SENDTO,Uri.parse("smsto:"+""));
intent.putExtra("sms_body", "我在安卓市場發現了個好東東【通訊錄】，快來......下載吧！！安卓市場里面還有很多應用來看看吧！");
startActivity(intent); 

 

發送彩信

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);

 

撥打電話

調撥打電話界面

Uri telUri = Uri. parse ( "tel:100861" );
returnIt = new Intent(Intent. ACTION_DIAL , telUri);

直接撥打電話

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

 要使用這個必須在配置文件中加入<uses-permission id="android.permission.CALL_PHONE" />

聯系人
進入聯系人頁面

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW); 
intent.setData(People.CONTENT_URI);
startActivity(intent);

打開聯系人列表 

//第一種
Intent i = new Intent(); 
i.setAction(Intent.ACTION_GET_CONTENT); 
i.setType("vnd.android.cursor.item/phone"); 
startActivityForResult(i, REQUEST_TEXT); 

//第二種
Uri uri = Uri.parse("content://contacts/people"); 
Intent it = new Intent(Intent.ACTION_PICK, uri); 
startActivityForResult(it, REQUEST_TEXT);

 

查看指定聯系人

Uri personUri = ContentUris.withAppendedId 
(People.CONTENT_URI, info.id);//info.id聯系人ID 
Intent intent = new Intent(); 
intent.setAction(Intent.ACTION_VIEW);
intent.setData(personUri);
startActivity(intent);

 

顯示網頁:

Uri uri = Uri.parse("http://www.google.com");
Intent it = new Intent(Intent.ACTION_VIEW,uri);
startActivity(it);

 

web瀏覽器

Uri uri= Uri. parse ( "http://kuikui.javaeye.com" );
returnIt = new Intent(Intent. ACTION_VIEW , uri );

 

顯示地圖:

Uri uri = Uri.parse("geo:38.899533,-77.036476");
Intent it = new Intent(Intent.Action_VIEW,uri);
startActivity(it);

 

發郵件

returnIt = new Intent(Intent. ACTION_SEND );

String[] tos = { "[e-mail]" };

String[] ccs = { "[e-mail]" };

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" );//真機上使用這行

//returnIt.setType("text/plain");//模擬器請使用這行
Intent. createChooser ( returnIt , "Choose Email 
Client" );

 

直接發郵件

Uri smsToUri = Uri. parse ( "smsto://100861" );
returnIt = new Intent(Intent. ACTION_SENDTO ,
smsToUri);
returnIt.putExtra( "sms_body" , "shenrenkui" );

發彩信

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

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"));

播放多媒體

Intent it = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.parse("file:///sdcard/song.mp3");

f=d&saddr=startLat%20startLng&daddr=endLat
%20endLng&hl=en");
Intent it = new Intent(Intent.ACTION_VIEW,uri );
startActivity(it);

null );
returnIt = new Intent(Intent. ACTION_PACKAGE_ADDED ,
installUri);

Uninstall 程序

Uri uri = Uri.fromParts("package", strPackageName,
