android 发短信、打电话、发邮件

短信

1.发送短信

需要权限 android.permission.SEND_SMS

使用android.telephony.SmsManager类

普遍使用的方式

private void sendSmsMessage(String address,String message)throws Exception    {        SmsManager smsMgr = SmsManager.getDefault();        Intent sent = new Intent();        sent.setAction("com.send");        PendingIntent sentIntent = PendingIntent.getBroadcast(this, 0, sent, 0);        Intent delivery = new Intent();        delivery.setAction("com.delivery");        PendingIntent deliveryIntent = PendingIntent.getBroadcast(this, 0, delivery , 0);        smsMgr.sendTextMessage(address, null, message, sentIntent, deliveryIntent);    } BroadcastReceiver send = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {if("com.send".equals(intent.getAction()))Toast.makeText(TelephonyDemo.this, "SMS send  success",                 Toast.LENGTH_LONG).show();}}; BroadcastReceiver delivery = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {if("com.delivery".equals(intent.getAction()))Toast.makeText(TelephonyDemo.this, "SMS delivery success",                 Toast.LENGTH_LONG).show();}};

另两种方式

sendDataMessage()接受一个附加参数以指定一个端口号，还会接受一个字节数组（不是一个String 消息）。

sendMultipartTextMessage()支持在整条消息大于SMS规范所允许的大小时发送文本消息。

SmsManager类提供了divideMessage()方法来帮助将较长的消息拆分为多个部分。

2.监视传入的SMS消息

需要权限：android.permission.RECEIVE_SMS

当设备收到SMS消息时，android会发出广播。该广播的action是android.provider.Telephony.SMS_RECEIVED

该action在文档上找不到，在源码的android.provider包下能找到Telephony类，其中有这么个action,同时有参数说明

  /**             * Broadcast Action: A new text based SMS message has been received             * by the device. The intent will have the following extra             * values:</p>             *             * <ul>             *   <li><em>pdus</em> - An Object[] od byte[]s containing the PDUs             *   that make up the message.</li>             * </ul>             *             * <p>The extra values can be extracted using             * {@link #getMessagesFromIntent(Intent)}.</p>             *             * <p>If a BroadcastReceiver encounters an error while processing             * this intent it should set the result code appropriately.</p>             */            @SdkConstant(SdkConstantType.BROADCAST_INTENT_ACTION)            public static final String SMS_RECEIVED_ACTION =                    "android.provider.Telephony.SMS_RECEIVED";

具体实现

<receiver android:name="MySMSMonitor"><intent-filter><action android:name="android.provider.Telephony.SMS_RECEIVED" /></intent-filter></receiver>public class MySMSMonitor extends BroadcastReceiver {private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";@Override    public void onReceive(Context context, Intent intent)    {if(intent!=null && intent.getAction()!=null &&         ACTION.compareToIgnoreCase(intent.getAction())==0)    {        Object[]pduArray = (Object[]) intent.getExtras().get("pdus");        SmsMessage[] messages = new SmsMessage[pduArray.length];        for (int i = 0; i<pduArray.length; i++) {            messages[i] = SmsMessage.createFromPdu((byte[])pduArray [i]);            Log.d("MySMSMonitor", "From: " + messages[i].getOriginatingAddress());            Log.d("MySMSMonitor", "Msg: " + messages[i].getMessageBody());        }        Log.d("MySMSMonitor","SMS Message Received.");    }}}

访问SMS文件夹

需要权限 android.permission.READ_SMS

要读取SMS消息，必须对SMS收件箱进行查询。如下所示

public class SMSInboxDemo extends ListActivity {    private ListAdapter adapter;    private static final Uri SMS_INBOX = Uri.parse("content://sms/inbox");    @Override    public void onCreate(Bundle bundle) {        super.onCreate(bundle);        Cursor c = getContentResolver()                .query(SMS_INBOX, null, null, null, null);        startManagingCursor(c);        String[] columns = new String[] { "body" };        int[] names = new int[] { R.id.row };        adapter = new SimpleCursorAdapter(this, R.layout.sms_inbox, c, columns,                names);        setListAdapter(adapter);    }}

以下是完整的SMS文件夹列表和每个文件夹的URI

所有文件夹 content://sms/all

收件箱 content://sms/inbox

已发送 content://sms/sent

草稿 content://sms/draft

发件箱 content://sms/outbox

发送失败 content://sms/failed

排队消息 content://sms/queued

未送达 content://sms/undelivered

对话 content://sms/conversations

发送电子邮件

android没有提供API来发送电子邮件，必须使用已注册的电子邮件应用程序。可以使用ACTION_SEND来启动电子邮件应用程序

 Intent emailIntent=new Intent(Intent.ACTION_SEND);        String subject = "Hi!";        String body = "hello from android....";        String[] extra = new String[]{"aaa@bbb.com"};              emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);        emailIntent.putExtra(Intent.EXTRA_TEXT, body);emailIntent.putExtra(Intent.EXTRA_EMAIL, extra);        emailIntent.setType("message/rfc822");        startActivity(emailIntent);

可以向电子邮件Intent添加的其他"extra"消息包括EXTRA_CC(抄送)、EXTRA_BCC(密送)。如果希望在邮件中发送电子邮件附件。可以使用以下代码。

emailIntent.putExtra(Intent.EXTRA_STREAM,Uri.fromFile(new File(myFileName)));

打电话

播出电话的最简单方法是使用以下代码

Intent intent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:12345678911"));startActivity(intent);

这段代码需要android.permission.CALL_PHONE权限。如果没有此权限，可以将Intent的操作更改为Intent.ACTION_VIEW.这会导致Dialer应用程序显示要拨打的目标号码，用户需要按下Send按钮才能开始呼叫。

监听电话状态

监听电话状态最简单的办法是在"android.intent.action.PHONE_STATE"上实现一个广播接收程序。可采用与上面监听传入的SMS消息相同的方式。

该action可以在文档中找到

http://developer.android.com/reference/android/telephony/TelephonyManager.html#ACTION_PHONE_STATE_CHANGED

另一种方式是使用TelephonyManager

 private TelephonyManager teleMgr = null; private MyPhoneStateListener myListener = null;@Override    protected void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);                teleMgr =                 (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);        myListener = new MyPhoneStateListener();    } @Override    public void onResume() {    super.onResume();    Log.d("PhoneCallDemo", "In onResume");        teleMgr.listen(myListener, PhoneStateListener.LISTEN_CALL_STATE);    }        @Override    public void onPause() {    super.onPause();    Log.d("PhoneCallDemo", "In onPause");        teleMgr.listen(myListener, PhoneStateListener.LISTEN_NONE);    }public class MyPhoneStateListener extends PhoneStateListener    {        @Override        public void onCallStateChanged(int state, String incomingNumber) {            super.onCallStateChanged(state, incomingNumber);            switch(state)            {                case TelephonyManager.CALL_STATE_IDLE:                    logText = "call state idle...incoming number is["+                                incomingNumber+"]\n" + logText;                    break;                case TelephonyManager.CALL_STATE_RINGING:                logText = "call state ringing...incoming number is["+                                incomingNumber+"]\n" + logText;                    break;                case TelephonyManager.CALL_STATE_OFFHOOK:                logText = "call state Offhook...incoming number is["+                                incomingNumber+"]\n" + logText;                    break;                default:                logText = "call state ["+state+"]incoming number is["+                                incomingNumber+"]\n" + logText;                    break;            }            print(logText);        }    }
