读取短信的Kotlin代码:

1-将此权限添加到AndroidManifest.xml:

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

创建BroadCastreceiver类:

package utils.broadcastreceivers

import android.content.BroadcastReceiver
import android.content.Context
import android.content.Intent
import android.telephony.SmsMessage
import android.util.Log

class MySMSBroadCastReceiver : BroadcastReceiver() {
override fun onReceive(context: Context?, intent: Intent?) {
    var body = ""
    val bundle = intent?.extras
    val pdusArr = bundle!!.get("pdus") as Array<Any>
    var messages: Array<SmsMessage?>  = arrayOfNulls(pdusArr.size)

 // if SMSis Long and contain more than 1 Message we'll read all of them
    for (i in pdusArr.indices) {
        messages[i] = SmsMessage.createFromPdu(pdusArr[i] as ByteArray)
    }
      var MobileNumber: String? = messages[0]?.originatingAddress
       Log.i(TAG, "MobileNumber =$MobileNumber")         
       val bodyText = StringBuilder()
        for (i in messages.indices) {
            bodyText.append(messages[i]?.messageBody)
        }
        body = bodyText.toString()
        if (body.isNotEmpty()){
       // Do something, save SMS in DB or variable , static object or .... 
                       Log.i("Inside Receiver :" , "body =$body")
        }
    }
 }

3-获得短信权限如果Android 6及以上:

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && 
    ActivityCompat.checkSelfPermission(context!!,
            Manifest.permission.RECEIVE_SMS
        ) != PackageManager.PERMISSION_GRANTED
    ) { // Needs permission

            requestPermissions(arrayOf(Manifest.permission.RECEIVE_SMS),
            PERMISSIONS_REQUEST_READ_SMS
        )

    } else { // Permission has already been granted

    }

4-将此请求代码添加到Activity或fragment:

 companion object {
    const val PERMISSIONS_REQUEST_READ_SMS = 100
   }

5- Override检查权限请求结果fun:

 override fun onRequestPermissionsResult(
    requestCode: Int, permissions: Array<out String>,
    grantResults: IntArray
) {
    when (requestCode) {

        PERMISSIONS_REQUEST_READ_SMS -> {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                Log.i("BroadCastReceiver", "PERMISSIONS_REQUEST_READ_SMS Granted")
            } else {
                //  toast("Permission must be granted  ")
            }
        }
    }
}

这篇文章有点老了，但这里有另一个简单的解决方案来获得Android中与SMS内容提供商相关的数据:

使用这个lib: https://github.com/EverythingMe/easy-content-providers

Get all SMS: TelephonyProvider telephonyProvider = new TelephonyProvider(context); List<Sms> smses = telephonyProvider.getSms(Filter.ALL).getList(); Each Sms has all fields, so you can get any info you need: address, body, receivedDate, type(INBOX, SENT, DRAFT, ..), threadId, ... Gel all MMS: List<Mms> mmses = telephonyProvider.getMms(Filter.ALL).getList(); Gel all Thread: List<Thread> threads = telephonyProvider.getThreads().getList(); Gel all Conversation: List<Conversation> conversations = telephonyProvider.getConversations().getList();

它与列表或光标一起工作，有一个示例应用程序来查看它的外观和工作方式。

事实上，有一个支持所有Android内容提供者，如:联系人，呼叫日志，日历，… 完整的文档，所有选项:https://github.com/EverythingMe/easy-content-providers/wiki/Android-providers

希望它也有帮助:)

这是一个微不足道的过程。您可以在源代码SMSPopup中看到一个很好的例子

检查以下方法:

SmsMmsMessage getSmsDetails(Context context, long ignoreThreadId, boolean unreadOnly)
long findMessageId(Context context, long threadId, long _timestamp, int messageType
void setMessageRead(Context context, long messageId, int messageType)
void deleteMessage(Context context, long messageId, long threadId, int messageType)

下面是阅读的方法:

SmsMmsMessage getSmsDetails(Context context,
                            long ignoreThreadId, boolean unreadOnly)
{
   String SMS_READ_COLUMN = "read";
   String WHERE_CONDITION = unreadOnly ? SMS_READ_COLUMN + " = 0" : null;
   String SORT_ORDER = "date DESC";
   int count = 0;
   // Log.v(WHERE_CONDITION);
   if (ignoreThreadId > 0) {
      // Log.v("Ignoring sms threadId = " + ignoreThreadId);
      WHERE_CONDITION += " AND thread_id != " + ignoreThreadId;
   }
   Cursor cursor = context.getContentResolver().query(
                      SMS_INBOX_CONTENT_URI,
                      new String[] { "_id", "thread_id", "address", "person", "date", "body" },
                      WHERE_CONDITION,
                      null,
                      SORT_ORDER);
   if (cursor != null) {
      try {
         count = cursor.getCount();
         if (count > 0) {
            cursor.moveToFirst();
            // String[] columns = cursor.getColumnNames();
            // for (int i=0; i<columns.length; i++) {
            // Log.v("columns " + i + ": " + columns[i] + ": " + cursor.getString(i));
            // }                                         
            long messageId = cursor.getLong(0);
            long threadId = cursor.getLong(1);
            String address = cursor.getString(2);
            long contactId = cursor.getLong(3);
            String contactId_string = String.valueOf(contactId);
            long timestamp = cursor.getLong(4);

            String body = cursor.getString(5);                             
            if (!unreadOnly) {
                count = 0;
            }

            SmsMmsMessage smsMessage = new SmsMmsMessage(context, address,
                          contactId_string, body, timestamp,
                          threadId, count, messageId, SmsMmsMessage.MESSAGE_TYPE_SMS);
            return smsMessage;
         }
      } finally {
         cursor.close();
      }
   }               
   return null;
}

第一步:首先我们必须在清单文件中添加权限 就像

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

步骤2:添加服务短信接收类，用于接收短信

<receiver android:name="com.aquadeals.seller.services.SmsReceiver">
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
    </intent-filter>
</receiver>

步骤3:添加运行时权限

private boolean checkAndRequestPermissions()
{
    int sms = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS);

    if (sms != PackageManager.PERMISSION_GRANTED)
    {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, REQUEST_ID_MULTIPLE_PERMISSIONS);
        return false;
    }
    return true;
}

第四步:在应用程序中添加这些类并进行测试 接口类

public interface SmsListener {
   public void messageReceived(String messageText);
}

SmsReceiver.java

public class SmsReceiver extends BroadcastReceiver {
    private static SmsListener mListener;
    public Pattern p = Pattern.compile("(|^)\\d{6}");
    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle data  = intent.getExtras();
        Object[] pdus = (Object[]) data.get("pdus");
        for(int i=0;i<pdus.length;i++)
        {
            SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);
            String sender = smsMessage.getDisplayOriginatingAddress();
            String phoneNumber = smsMessage.getDisplayOriginatingAddress();
            String senderNum = phoneNumber ;
            String messageBody = smsMessage.getMessageBody();
            try{
                if(messageBody!=null){
                    Matcher m = p.matcher(messageBody);
                    if(m.find()) {
                        mListener.messageReceived(m.group(0));
                    }
                }
            }
            catch(Exception e){}
        }
    }
    public static void bindListener(SmsListener listener) {
        mListener = listener; 
    }
}

使用内容解析器(" Content://sms/inbox")来读取收件箱中的sms。

// public static final String INBOX = "content://sms/inbox";
// public static final String SENT = "content://sms/sent";
// public static final String DRAFT = "content://sms/draft";
Cursor cursor = getContentResolver().query(Uri.parse("content://sms/inbox"), null, null, null, null);

if (cursor.moveToFirst()) { // must check the result to prevent exception
    do {
       String msgData = "";
       for(int idx=0;idx<cursor.getColumnCount();idx++)
       {
           msgData += " " + cursor.getColumnName(idx) + ":" + cursor.getString(idx);
       }
       // use msgData
    } while (cursor.moveToNext());
} else {
   // empty box, no SMS
}

请添加READ_SMS权限。

String WHERE_CONDITION = unreadOnly ? SMS_READ_COLUMN + " = 0" : null;

改变了:

String WHERE_CONDITION = unreadOnly ? SMS_READ_COLUMN + " = 0 " : SMS_READ_COLUMN + " = 1 ";
