android中发送短信很简单,
首先要在Mainfest.xml中加入所需要的权限:
1
2
3
|
<
uses-permission
android:name
=
"android.permission.SEND_SMS"
></
uses-permission
>
<
uses-permission
android:name
=
"android.permission.READ_SMS"
></
uses-permission
>
<
uses-permission
android:name
=
"android.permission.RECEIVE_SMS"
></
uses-permission
>
|
为了后面测试方便,干脆把SMS的所有权限加上。
方法1:

public
class
testSms
extends
Activity {
...
private
void
send1(String phone, String message){
PendingIntent pi = PendingIntent.getActivity(
this
,
0
,
new
Intent(
this
, testSms.
class
),
0
);
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phone,
null
, message, pi,
null
);
}
}
|
方法2:
如果想知道短信发送后的状态,需要两个Receiver来实现
1

private
void
send2(String number, String message){
String SENT =
"sms_sent"
;
String DELIVERED =
"sms_delivered"
;
PendingIntent sentPI = PendingIntent.getActivity(
this
,
0
,
new
Intent(SENT),
0
);
PendingIntent deliveredPI = PendingIntent.getActivity(
this
,
0
,
new
Intent(DELIVERED),
0
);
registerReceiver(
new
BroadcastReceiver(){
@Override
public
void
onReceive(Context context, Intent intent) {
switch
(getResultCode())
{
case
Activity.RESULT_OK:
Log.i(
"====>"
,
"Activity.RESULT_OK"
);
break
;
case
SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Log.i(
"====>"
,
"RESULT_ERROR_GENERIC_FAILURE"
);
break
;
case
SmsManager.RESULT_ERROR_NO_SERVICE:
Log.i(
"====>"
,
"RESULT_ERROR_NO_SERVICE"
);
break
;
case
SmsManager.RESULT_ERROR_NULL_PDU:
Log.i(
"====>"
,
"RESULT_ERROR_NULL_PDU"
);
break
;
case
SmsManager.RESULT_ERROR_RADIO_OFF:
Log.i(
"====>"
,
"RESULT_ERROR_RADIO_OFF"
);
break
;
}
}
},
new
IntentFilter(SENT));
registerReceiver(
new
BroadcastReceiver(){
@Override
public
void
onReceive(Context context, Intent intent){
switch
(getResultCode())
{
case
Activity.RESULT_OK:
Log.i(
"====>"
,
"RESULT_OK"
);
break
;
case
Activity.RESULT_CANCELED:
Log.i(
"=====>"
,
"RESULT_CANCELED"
);
break
;
}
}
},
new
IntentFilter(DELIVERED));
SmsManager smsm = SmsManager.getDefault();
smsm.sendTextMessage(number,
null
, message, sentPI, deliveredPI);
}
|
在模拟器上是看不到Receiver中的log信息的,据网上说在手机上是可以实现的,只可惜手中无机,也只能纸上谈兵了。
方法3:
上面都是发送文本文件,如果想发送一些非文本,比如加密数据,可以用以下方法:
1
2
3
4
5
6
|
private
void
send2(String number, String message){
SmsManager smsm = SmsManager.getDefault();
short
port =
1000
;
PendingIntent pi = PendingIntent.getBroadcast(test.
this
,
0
,
new
Intent(),
0
);
smsm.sendDataMessage(number,
null
, port, message.getBytes(), pi,
null
);
}
|
方法4:
调用系统的短信界面,这个方法需要用户自己输入接收方的电话号码
1
2
3
4
5
|
private
void
send(String message){
Intent sendIntent =
new
Intent(Intent.ACTION_VIEW);
sendIntent.putExtra(
"sms_body"
, message);
sendIntent.setType(
"vnd.android-dir/mms-sms"
);
}
|
这个方法自动设置接收方的号码
1
2
3
4
5
6
|
private
void
send1(String number, String message){
Uri uri = Uri.parse(
"smsto:"
+ number);
Intent sendIntent =
new
Intent(Intent.ACTION_VIEW, uri);
sendIntent.putExtra(
"sms_body"
, message);
startActivity(sendIntent);
}
|
短信的接受,需要实现BroadcastReceiver类,监听系统消息
首先在Mainfest.xml中加入申明,SmsReceiver为实现类
1
2
3
4
5
6
7
|
<
receiver
android:name
=
".SmsReceiver"
>
<
intent-filter
>
<
action
android:name
=
"android.provider.Telephony.SMS_RECEIVED"
/>
</
intent-filter
>
</
receiver
>
|
如果是方法3,使用sendDataMessage时需要加入
1
2
3
4
5
6
7
8
9
10
|
<
receiver
android:name
=
".SmsReceiver"
>
<
intent-filter
>
<
action
android:name
=
"android.intent.action.DATA_SMS_RECEIVED"
/>
<
data
android:scheme
=
"sms"
/>
<
data
android:host
=
"localhost"
/>
<
data
android:port
=
"1000"
/>
</
intent-filter
>
</
receiver
>
|
将其中的dat数据注释掉,模拟器上也可以接收到短信; port跟sendDataMessage中的端口值不一致时,也没有问题,太神奇了

public
class
SmsReceiver
extends
BroadcastReceiver {
@Override
public
void
onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
SmsMessage[] msgs =
null
;
String phone;
String message;
if
(bundle !=
null
){
Object[] pdus = (Object[])bundle.get(
"pdus"
);
msgs =
new
SmsMessage[pdus.length];
for
(
int
i =
0
; i < msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((
byte
[])pdus[i]);
phone = msgs[i].getOriginatingAddress();
message = msgs[i].getMessageBody();
}
}
}
}

如果是sendDataMessage发送:

@Override

void
onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
SmsMessage[] msgs =
null
;
String phone;
String message;
if
(bundle !=

){
Object[] pdus = (Object[])bundle.get(
"pdus"

msgs =
new
SmsMessage[pdus.length];
for
(
int
i =
0
; i < msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((
byte

phone = msgs[i].getOriginatingAddress();
byte
data[] = SmsMessage.createFromPdu((
byte
[])pdus[i]).getUserData();
message =
new
String(data);
}
}
}
}

不一样的地方是message的获取时使用getUserData()方法。
