Android(安卓)发短信功能实现

在自己的应用增加发短信功能有两种方式：

1，跳转到系统短信页面发送，调用如下代码即可。

Intent intent = new Intent(Intent.ACTION_SENDTO, Uri

.parse("smsto:" + telnum));

// 如果需要将内容传过去增加如下代码

intent .putExtra("sms_body", body);
startActivity(intent);

2，调用系统发短信接口sendTextMessage。activity如下：

布局文件就是两个输入框和一个发送按钮。

AndroidManifest.xml需要权限

public class MainTestActivity extends Activity {

private static final String SENT_SMS_ACTION = "demo_sms_send_action";
private static final String KEY_PHONENUM = "phone_num";
private EditText mPhoneNumberEdit;
private EditText mContentEdit;
private Button mSendBtn;
protected Context mContext;
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_test);
mContext = this;;
mPhoneNumberEdit = (EditText) findViewById(R.id.phonenumber);
mContentEdit = (EditText) findViewById(R.id.content);
mSendBtn = (Button) findViewById(R.id.send);
mSendBtn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
String phone = mPhoneNumberEdit.getText().toString().trim();
String content = mContentEdit.getText().toString().trim();
if (TextUtils.isEmpty(phone) && TextUtils.isEmpty(content)) {
Toast.makeText(mContext, "input message!", Toast.LENGTH_LONG).show();
return;
}
sendSMS(phone,content);
}

});

//注册短信发送状态的广播

mReceiver = new SMSSendResultReceiver();
IntentFilter filter = new IntentFilter(SENT_SMS_ACTION);
registerReceiver(mReceiver, filter);
}

/**
* 直接调用短信接口发短信如果群发可以循环调用
* @param phoneNumber
* @param message
*/
public void sendSMS(String phoneNumber,String message){
//获取短信管理器
android.telephony.SmsManager smsManager = android.telephony.SmsManager.getDefault();
//拆分短信内容（手机短信长度限制）
List divideContents = smsManager.divideMessage(message);
Intent itSend = new Intent(SENT_SMS_ACTION);
itSend.putExtra(KEY_PHONENUM, phoneNumber);
PendingIntent sentPI = PendingIntent.getBroadcast(getApplicationContext(), 0, itSend, PendingIntent.FLAG_UPDATE_CURRENT);
for (String text : divideContents) {
smsManager.sendTextMessage(phoneNumber, null, text, sentPI, null);
}

}

SMSSendResultReceiver mReceiver;

// 监听短信发送状态

class SMSSendResultReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
if (SENT_SMS_ACTION.equals(intent.getAction())) {
String phoneNum = intent.getStringExtra(KEY_PHONENUM);
switch(getResultCode())
{

case Activity.RESULT_OK:

// 发送成功

Toast.makeText(context, "Send Message to "+phoneNum+" success!", Toast.LENGTH_LONG).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
case SmsManager.RESULT_ERROR_RADIO_OFF:
case SmsManager.RESULT_ERROR_NULL_PDU:

default:

// 发送失败

Toast.makeText(context, "Send Message to "+phoneNum+" fail!", Toast.LENGTH_LONG).show();
break;
}
}
}
}

@Override
protected void onDestroy() {
super.onDestroy();
if (mReceiver != null) {
unregisterReceiver(mReceiver);
}
}

}

sendTextMessage的参数说明：

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。
