Android学习--多媒体功能：接收和发送短信

效果图：

拨打1008611后会有短信过来







几秒钟后，Toast出消息，短信送达，对方已接收



同一时间，这边用于测试的手机收到短信



代码如下：

MainActivity.java

package com.example.smstest;

import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity implements OnClickListener {

private TextView sender;
private TextView content;
private EditText to;// 接收人号码
private EditText msgInput;// 短信内容
private Button send;// 发送按钮

private IntentFilter receiveFilter, sendFilter, deliveryFilter;// 过滤器
private MessageReceiver messageReceiver;// 短信接收广播接收器，下面自定义这个广播
private SendStatusReceiver sendstatusReceiver;// 发送状态广播接收器,下面自定义这个广播
private DeliveryReceiver deliveryReceiver;// 短信送达状态广播，下面定义这个广播

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

receiveFilter = new IntentFilter();
receiveFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
receive
4000
Filter.setPriority(100);// 设置优先级，不设置则接收不到，我也不知道为什么
messageReceiver = new MessageReceiver();
registerReceiver(messageReceiver, receiveFilter);// 注册短信接收广播

sendFilter = new IntentFilter();
sendFilter.addAction("SENT_SMS_ACTION");
sendstatusReceiver = new SendStatusReceiver();
registerReceiver(sendstatusReceiver, sendFilter);// 注册发送状态广播

deliveryFilter = new IntentFilter();
deliveryFilter.addAction("SENT_SMS_ACTION");
deliveryReceiver = new DeliveryReceiver();
registerReceiver(deliveryReceiver, deliveryFilter);// 注册送达状态广播

sender = (TextView) findViewById(R.id.sender);

to = (EditText) findViewById(R.id.to);
msgInput = (EditText) findViewById(R.id.msg_input);
send = (Button) findViewById(R.id.send);
send.setOnClickListener(this);// 按钮事件在最下方写出，这里设置监听
}

class MessageReceiver extends BroadcastReceiver {// 定义短信接收广播
/*
* 首先从Intent参数中取出一个Bundle对象，然后使用pdu密钥来提取一个SMS pdus数组，其中
* 每一个pdu都表示一条短信消息。接着使用SmsMessage的createFromPdu()方法将每一个
* pdu字节数组转换为SmsMessage对象，调用这个对象的getOriginatingAddress()方法
* 就可以获取到发送短信的发送方号码，调用getMessageBody()方法就可以获取到短信的内容，然后
* 将获取到的发送方号码和短信内容显示在TextView上。

@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub\

Bundle bundle = intent.getExtras();

SmsMessage[] messages = new SmsMessage[pdus.length];
for (int i = 0; i < messages.length; i++) {
messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
String address = messages[0].getOriginatingAddress();// 获取发送方号码
String fullMessage = "";
for (SmsMessage message : messages) {
if (message != null) {// 1008611来的短信前面会留白，使头几个字节为空，所以在此做一个判断，空格不是空字节。
fullMessage += message.getMessageBody();// 获取短信内容
}
}
// 如果号码前面带有+86，那么字符串从第四个开始取，即删除“+86”
if (address.contains("+86")) {
address = address.substring(3);
}
sender.setText(address);
content.setText(fullMessage);
// Toast.makeText(context,"接收到了短信",
// Toast.LENGTH_SHORT).show();//定义优先级之前用于检测广播是否接收
this.abortBroadcast();
// 部分手机比如小米手机略屌，有个变态设定防止应用更改系统通知，
// 要修改进入小米短信应用,按菜单键,选择设置选项,拉倒最下面一行的高级设置选中打开,有个系统短信优先开关,把这个关闭,就能使用abortBroadcast方法拦截短信了。
}
}
}
