java发送和接收短信以验证手机号码

Question

我正在尝试不使用第三方进行手机号码验证。为此，我的逻辑是：-

• 用户使用国家/地区代码输入其手机号码
• 当他们点击verify按钮时，intent会向用户定义的手机号码发送一条带有随机唯一id的短信
• 之后，应用程序广播将等待2分钟，当它收到短信，然后用户可以登录或注册

这个逻辑是正确的还是需要修改

要发送短信，我正在使用此代码，但不知道如何接收和验证该号码

 String phoneNumber = "9999999999";
 String smsBody = "Message from the API";

 // Get the default instance of SmsManager
 SmsManager smsManager = SmsManager.getDefault();
 // Send a text based SMS
 smsManager.sendTextMessage(phoneNumber, null, smsBody, null, null);

更新：-

未在三星设备上接收信息

this requires 安卓.permission.INTERACT_ACROSS_USERS_FULL

Answer 1

首先，我生成一个范围在10000到99999之间的随机数

 Random rNo = new Random();
 final int code = rNo.nextInt((99999 - 10000) + 1) + 10000;

接下来，我会显示一个弹出窗口，提示用户手机将发送一条消息来验证号码。这是使用AlertDialog完成的

final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Verify Phone Number");
builder.setMessage("An sms will be sent to the number " + phNo + " for verification. Charges will apply as per your plan");
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(final DialogInterface dialog, int which) {
                //code to send sms here with the code value
                final ProgressDialog progressdialog = ProgressDialog.show(getActivity(), "Waiting for SMS", "Please hold on");

                final CountDownTimer timer = new CountDownTimer(120000, 1000) {
                    @Override
                    public void onTick(long millisUntilFinished) {
                    Log.v("ranjapp", "Ticking " + millisUntilFinished / 1000);
                     progressdialog.setMessage("Waiting for the message " + millisUntilFinished / 1000);
                    }

                    @Override
                    public void onFinish() {
                     getActivity().unregisterReceiver(receiver);
                     progressdialog.dismiss();

                    }
                }.start();

                receiver = new BroadcastReceiver() {
                    @Override
                    public void onReceive(Context context, Intent intent) {
                        Bundle bundle = intent.getExtras();
                        if (bundle != null) {
                            if (readSMS(intent, code)) {
                                Log.v("ranjapp", "SMS read");
                                timer.cancel();
                                try {
                                    getActivity().unregisterReceiver(receiver);
                                } catch (Exception e) {
                                }
                            }
                        }
                    }
                };
     getActivity().registerReceiver(receiver, new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));
            }
        }

);
builder.setNegativeButton("CANCEL", new DialogInterface.OnClickListener()

        {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        }

);
builder.show();

以上代码说明：

在用户确认发送短信后，会向输入的号码发送带有代码的短信，该号码应该是用户自己使用的号码。因此，我们将等待一条带有代码的短信，接收短信并读取其内容，我们将创建一个BroadCastReceiver来监听传入的短信

现在我们还需要启动一个计时器，这样我们只需要等待2分钟的短信，所以我们启动一个CountDownTimer2分钟，在2分钟结束时，倒计时将注销接收器。即使在收到的短信中收到了代码，接收者也会被注销，这样我们就可以释放资源了

readSMS的代码，如果发现该代码为true，则返回，否则返回false

boolean readSMS(Intent intent, int code) {
        try {
            Bundle bundle = intent.getExtras();
            if (bundle != null) {
                Object[] pdusObj = (Object[]) bundle.get("pdus");
                for (int i = 0; i < pdusObj.length; i++) {
                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();
                    String senderNum = phoneNumber;
                    String message = currentMessage.getDisplayMessageBody();
                    if (message.contains(String.valueOf(code)))
                        return true;
                }
            }
        } catch (Exception e) {
            Log.v("ranjapp", "Exception here " + e.toString());
            return false;
        }
        return false;
    }

要发送短信，请使用以下方法：

public static void sendSMS(Context context, String incomingNumber, String sms) {
        DateTimeFormatter dtfOut = DateTimeFormat.forPattern("YYYY-MM-dd HH:MM:SS");
        SmsManager smsManager = SmsManager.getDefault();                                      //send sms
        try {
            ArrayList<String> parts = smsManager.divideMessage(sms);
            smsManager.sendMultipartTextMessage(incomingNumber, null, parts, null, null);

            RecContDBHelper recContDBHelper = new RecContDBHelper(context);
            recContDBHelper.insertRecord(new ContactData("", incomingNumber, dtfOut.print(MutableDateTime.now())));
            Log.v("ranjith", "Sms to be sent is " + sms);
        } catch (Exception e) {
            Log.v("ranjith", e + "");
        }
    }

在AndroidManifest中。xml您需要具有以下权限：

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

Answer 2

您可以使用内容提供商访问sms收件箱

    ContentResolver contentResolver =getContentResolver();
    Uri uri = Uri.parse("content://sms/inbox");
    //query here
