Android监听手机短信的示例代码

本文介绍了Android监听手机短信的示例代码，分享给大家，具体如下：

以下情况可能会导致短信拦截失败:

1. 小米,360等品牌手机拦截短信,短信的优先级给了系统
2. 用户禁用短信权限
3. 手机连接电脑,被电脑端的手机助手类软件截获
4. 手机内装有QQ通讯录之类的管理联系人,短信的应用,被截获.

前提--权限：

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

定义短信广播接收者

public class SMSBroadcastReceiverextends BroadcastReceiver{

  private static OnReceivedMessageListener mOnReceivedMessageListener;
  public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";

  public SMSBroadcastReceiver(){
    super();
  }

  @Override
  public void onReceive(Context context, Intent intent){
    if (intent.getAction().equals(SMS_RECEIVED_ACTION)) {
      Object[] pdus = (Object[]) intent.getExtras().get("pdus");
      for(Object pdu:pdus) {
        SmsMessage smsMessage = SmsMessage.createFromPdu((byte [])pdu);
        String sender = smsMessage.getDisplayOriginatingAddress();
        String content = smsMessage.getDisplayMessageBody();
        long date = smsMessage.getTimestampMillis();
        Date tiemDate = new Date(date);
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String time = simpleDateFormat.format(tiemDate);
        //过滤不需要读取的短信的发送号码
        if ("106902780116481".equals(sender)) {
          mOnReceivedMessageListener.onReceived(getDynamicPassword(content));
          abortBroadcast();
        }
      }
    }
  }

  public interface OnReceivedMessageListener{
    void onReceived(String message);
  }

  public void setOnReceivedMessageListener(OnReceivedMessageListener onReceivedMessageListener){
    this.mOnReceivedMessageListener = onReceivedMessageListener;
  }

  /**
   * 从字符串中截取连续6位数字组合 ([0-9]{" + 6 + "})截取六位数字 进行前后断言不能出现数字 用于从短信中获取动态密码
   * @param str 短信内容
   * @return 截取得到的6位动态密码
   */
  public String getDynamicPassword(String str){
    // 6是验证码的位数,一般为六位
    Pattern continuousNumberPattern = Pattern.compile("(?<![0-9])([0-9]{" + 6 + "})(?![0-9])");
    Matcher m = continuousNumberPattern.matcher(str);
    String dynamicPassword = "";
    while (m.find()) {
      dynamicPassword = m.group();
    }
    return dynamicPassword;
  }
}

注册广播

SMSBroadcastReceiver = mSMSBroadcastReceiver = new SMSBroadcastReceiver();
IntentFilter intentFilter = new IntentFilter(SMSBroadcastReceiver.SMS_RECEIVED_ACTION);
intentFilter.setPriority(Integer.MAX_VALUE);
this.registerReceiver(mSMSBroadcastReceiver, intentFilter);
ToastManager.getInstance().showLongToast("注册短信监听");

mSMSBroadcastReceiver.setOnReceivedMessageListener(new SMSBroadcastReceiver.OnReceivedMessageListener() {
 @Override
 public void onReceived(String message){
 //do something
 }
});

方式二:监听短信数据库

内容提供者中对外通信方式有3种:

方式1:定义为Activity的内部类,直接在onChang()方法中处理业务逻辑,比如收到短信之后设置给EditText

1. 优点:方便
2. 缺点:耦合度高,复用性差

方式2:定义接口,Activity实现这个接口,拿到回调,处理业务逻辑

1. 优点:耦合度低,复用性高
2. 缺点没用充分利用Handler资源

代码如下:

/**
 * Created by wxw on 2016/9/24 10:34
 * function: 监听短信数据库
 * e-mail:wangxw725@163.com
 */
public class SmsContentObserverextends ContentObserver{
  private Cursor cursor = null;
  private Context mContext;
  private String[] projection = new String[]{"_id","body"};
  private OnMessageObservedListener mOnMessageObservedListener;

  public SmsContentObserver(Context context,Handler handler){
    super(handler);
    this.mContext = context;
  }

  public interface OnMessageObservedListener{
    void onObservedMessage(String message);
  }
  public void setOnMessageObservedListener(OnMessageObservedListener onMessageObservedListener){
    this.mOnMessageObservedListener = onMessageObservedListener;
  }

  @Override
  public void onChange(boolean selfChange){
    super.onChange(selfChange);

    cursor = mContext.getContentResolver().query(Uri.parse("content://sms/inbox"), projection,null, null, "_id desc");

    if (cursor != null && cursor.getCount() > 0) {
      cursor.moveToNext();
      int smsbodyColumn = cursor.getColumnIndex("body");
      String smsBody = cursor.getString(smsbodyColumn);
      mOnMessageObservedListener.onObservedMessage(getDynamicPassword(smsBody));
    }
    cursor.close();
  }

  private String getDynamicPassword(String str){
    Pattern continuousNumberPattern = Pattern.compile("(?<![0-9])([0-9]{" + 6 + "})(?![0-9])");
    Matcher m = continuousNumberPattern.matcher(str);
    String dynamicPassword = "";
    while (m.find()) {
      dynamicPassword = m.group();
    }
    return dynamicPassword;
  }
}

方式3:通过Handler发送消息,在Activity中进行业务逻辑处理

代码如下:

/**
 * Created by wxw on 2016/9/24 10:34
 * function: 监听短信数据库
 * e-mail:wangxw725@163.com
 */
public class SmsContentObserverextends ContentObserver{
  private Cursor cursor = null;
  private Context mContext;
  private Handler mHandler;
  private String[] projection = new String[]{"_id","body"};

  public SmsContentObserver(Context context,Handler handler){
    super(handler);
    this.mContext = context;
    this.mHandler = handler;
  }

  @Override
  public void onChange(boolean selfChange){
    super.onChange(selfChange);
    cursor = mContext.getContentResolver().query(Uri.parse("content://sms/inbox"), projection,null, null, "_id desc");

    if (cursor != null && cursor.getCount() > 0) {
      cursor.moveToNext();
      int smsbodyColumn = cursor.getColumnIndex("body");
      String smsBody = cursor.getString(smsbodyColumn);
      mHandler.obtainMessage(1,getDynamicPassword(smsBody)).sendToTarget();
    }
    cursor.close();
  }

  private String getDynamicPassword(String str){
    Pattern continuousNumberPattern = Pattern.compile("(?<![0-9])([0-9]{" + 6 + "})(?![0-9])");
    Matcher m = continuousNumberPattern.matcher(str);
    String dynamicPassword = "";
    while (m.find()) {
      dynamicPassword = m.group();
    }
    return dynamicPassword;
  }
}

注册观察者

smsContentObserver = new SmsContentObserver(this, smsHandler);
getContentResolver().registerContentObserver(Uri.parse("content://sms/"), true, smsContentObserver);

handler中处理消息

private Handler smsHandler = new Handler(){
 @Override
 public void handleMessage(Message msg){

 switch (msg.what){
  case 0:
  ......
  break;
  case 1:
  LogUtils.x("Activity收到了短息码:"+(String)msg.obj);
  lf.mEtPassword.setText((String)msg.obj);
  break;
 }
 }
};

注销观察者

@Override
protected void onDestroy(){
 super.onDestroy();
 ......
 if(smsContentObserver!=null){
 getContentResolver().unregisterContentObserver(smsContentObserver);
 smsContentObserver = null;
 }
}

遗留问题

观察者会多次回调onChang方法()
