Android开发app实现发送短信功能

程序使用手机发短信的方法

短信收发：

◆发送短信只需要几行代码，如下：

SmsManager sms = SmsManager.getDefault();

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

sms.sendTextMessage(phoneNumber, null, MsgStr, pi, null);

其中参数phoneNumber和MsgStr均是String类型，表示接收方的电话号码和短信内容

◆接收短信主要是继承BroadcaseReceiver 类 ,覆盖onReceive 函数：

package com.android.TinySMS;

import android.app.Activity;

import android.app.PendingIntent;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.os.Bundle;

import android.telephony.gsm.SmsManager;

import android.view.View;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;

public class TinySMS extends Activity {

public static final String SMS_ACTION = "com.android.TinySMS.RESULT";

// private TextView message;

private Button snd;

private EditText tel;

private EditText txt;

private SentReceiver receiver = new SentReceiver();

private class SentReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

if (intent.getAction().equals(SMS_ACTION)) {

int code = getResultCode();

//短消息发送成功

if(code == Activity.RESULT_OK)

Toast.makeText(TinySMS.this, R.string.msg_sent,

Toast.LENGTH_SHORT).show();

}

};

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

tel = (EditText) findViewById(R.id.EditText01);

tel.setText("5554"); //模拟器之间互发短信

txt = (EditText) findViewById(R.id.EditText02);

txt.setText("我用自己的程序试试发短信。");

snd = (Button) findViewById(R.id.Button01);

snd.setOnClickListener(new View.OnClickListener() {

public void onClick(View arg0) {

String phoneNo = tel.getText().toString();

String message = txt.getText().toString();

if (phoneNo.length()>0 && message.length()>0){

sendSMS(phoneNo, message);

} else {

Toast.makeText(TinySMS.this,

"请重新输入电话号码和短信内容",

Toast.LENGTH_LONG).show();

}

});

}

private void sendSMS(String address, String content)

{

SmsManager manager = SmsManager.getDefault();

Intent i = new Intent(SMS_ACTION);

//生成PendingIntent，当消息发送完成，接收到广播

PendingIntent sentIntent = PendingIntent.getBroadcast(

this,

PendingIntent.FLAG_ONE_SHOT);

manager.sendTextMessage(

address,

null,

content,

sentIntent,

null);

}

如果要收发短信，还需在AndroidManifest.xml中声明权限：

<uses-permission android:name="android.permission.READ_SMS"></uses-permission>

<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
