这是我发送短信的代码

import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class SMSTest extends Activity
{
Button btnSendSMS;
EditText txtPhoneNo;
EditText txtMessage;

在第一次创建活动时调用。

@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.sendingsms);
btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo);
txtMessage = (EditText) findViewById(R.id.txtMessage); 

btnSendSMS.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
String phoneNo = txtPhoneNo.getText().toString();
String message = txtMessage.getText().toString();
if (phoneNo.length()>0 && message.length()>0)
sendSMS(phoneNo, message);
else
Toast.makeText(getBaseContext(),
"Please enter both phone number and message.",
Toast.LENGTH_SHORT).show();
}
});
}

向另一台设备发送 SMS 消息

private void sendSMS(String phoneNumber, String message)
{

String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";

PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
new Intent(SENT), 0);

PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
new Intent(DELIVERED), 0);

//—when the SMS has been sent—
registerReceiver(new BroadcastReceiver(){
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS sent",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), "Generic failure",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(), "No service",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), "Null PDU",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), "Radio off",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(SENT));

//—when the SMS has been delivered—
registerReceiver(new BroadcastReceiver(){
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS delivered",
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(), "SMS not delivered",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(DELIVERED));

SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
}
}

此代码用于接收短信

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;

public class SmsReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
//—get the SMS message passed in—
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String str = "";
if (bundle != null)
{
//—retrieve the SMS message received—
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]);
str += "SMS from " + msgs[i].getOriginatingAddress();
str += " :";
str += msgs[i].getMessageBody().toString();
str += "\n";
}
//—display the new SMS message—
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
}
}
}

这是XML文件..

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Enter the phone number of recipient"
    />
    <EditText
    android:id="@+id/txtPhoneNo"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    />
    <TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Message"
    />
    <EditText
    android:id="@+id/txtMessage"
    android:layout_width="fill_parent"
    android:layout_height="150px"
    android:gravity="top"
    />
    <Button
    android:id="@+id/btnSendSMS"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Send SMS"
    />
    </LinearLayout>

非常基本的应用程序..我需要知道是否可以通过编码发送短信...如果不是，那么whatsApp如何允许我们免费发送短信..他们付费吗？？..或者我们可以使用一些API .. .

WhatsApp在应用程序中不使用基于运营商的短信，只是WhatsApp有自己的服务器，当你打开应用程序时，你连接到他们的服务器，当你的朋友也登录时，你们都连接到服务器，所以在这个当你们俩之间有一个开放的频道时，你用它来聊天和发送文件等

很简单，不是吗：）

WhatsApp 不会向其他设备发送短信。消息通过 IM 发送 - http://en.wikipedia.org/wiki/Extensible_Messaging_and_Presence_Protocol
