Android监听手机短信的示例代码

2019年07月24日  | 移动技术网移动技术  | 我要评论

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()
