读取特定号码的收件箱信息并在活动中显示它们

Question

我试图从收件箱中读取消息并在活动中显示它们。我的活动包含一个按钮和列表视图。当我点击按钮时，所有来自收件箱的消息都会显示。但我的要求是我需要查看来自特定号码的消息。当我从该号码获取消息时，我的应用程序不在运行，当我点击按钮时，只有特定的消息（与特定号码相关）必须更新。

这是相关代码。

myActivity.java：

public class SecureMessagesActivity extends Activity implements OnClickListener, OnItemClickListener {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setTheme( android.R.style.Theme_Light );
        setContentView(R.layout.main);
        this.findViewById( R.id.UpdateList ).setOnClickListener( this );
    }

    ArrayList<String> smsList = new ArrayList<String>();

    public void onItemClick( AdapterView<?> parent, View view, int pos, long id ) {
        try {
            String[] splitted = smsList.get( pos ).split("\n"); 
            String sender = splitted[0];
            String encryptedData = "";

            for ( int i = 1; i < splitted.length; ++i ) {
                encryptedData += splitted[i];
            }
            String data = sender + "\n" + StringCryptor.decrypt( new String(SmsReceiver.PASSWORD), encryptedData );
            Toast.makeText( this, data, Toast.LENGTH_SHORT ).show();
        } 
        catch (Exception e) {
                e.printStackTrace();
        }
    }

    public void onClick( View v ) {
        ContentResolver contentResolver = getContentResolver();
        Cursor cursor = contentResolver.query( Uri.parse( "content://sms/inbox" ), null, null, null, null);

        int indexBody = cursor.getColumnIndex( SmsReceiver.BODY );
        int indexAddr = cursor.getColumnIndex( SmsReceiver.ADDRESS );

        if ( indexBody < 0 || !cursor.moveToFirst() ) return;

        smsList.clear();

        do {
            String str = "Sender: " + cursor.getString( indexAddr ) + "\n" + cursor.getString( indexBody );
            smsList.add( str );
        }
        while( cursor.moveToNext() );

        ListView smsListView = (ListView) findViewById( R.id.SMSList );
        smsListView.setAdapter( new ArrayAdapter<String>( this, android.R.layout.simple_list_item_1, smsList) );
        smsListView.setOnItemClickListener( this );
    }
} 

SmsReceiver.java：

public class SmsReceiver extends BroadcastReceiver {
    public static final String SMS_EXTRA_NAME = "pdus";
    public static final String SMS_URI = "content://sms";

    public static final String ADDRESS = "address";
    public static final String PERSON = "person";
    public static final String DATE = "date";
    public static final String READ = "read";
    public static final String STATUS = "status";
    public static final String TYPE = "type";
    public static final String BODY = "body";
    public static final String SEEN = "seen";

    public static final int MESSAGE_TYPE_INBOX = 1;
    public static final int MESSAGE_TYPE_SENT = 2;

    public static final int MESSAGE_IS_NOT_READ = 0;
    public static final int MESSAGE_IS_READ = 1;

    public static final int MESSAGE_IS_NOT_SEEN = 0;
    public static final int MESSAGE_IS_SEEN = 1;


    public static final byte[] PASSWORD = new byte[]{ 0x20, 0x32, 0x34, 0x47, (byte) 0x84, 0x33, 0x58 };

    public void onReceive( Context context, Intent intent ) {

        Bundle extras = intent.getExtras();
        String messages = "";

        if ( extras != null ) {
            Object[] smsExtra = (Object[]) extras.get( SMS_EXTRA_NAME );
            ContentResolver contentResolver = context.getContentResolver();

            for ( int i = 0; i < smsExtra.length; ++i ) {
                SmsMessage sms = SmsMessage.createFromPdu((byte[])smsExtra[i]);

                String body = sms.getMessageBody().toString();
                String address = sms.getOriginatingAddress();

                messages += "SMS from " + address + " :\n";                    
                messages += body + "\n";
                putSmsToDatabase( contentResolver, sms );
            }

            // Display SMS message
            Toast.makeText( context, messages, Toast.LENGTH_SHORT ).show();
        }

        // WARNING!!! 
        // If you uncomment next line then received SMS will not be put to incoming.
        // Be careful!
        // this.abortBroadcast(); 
    }

    private void putSmsToDatabase( ContentResolver contentResolver, SmsMessage sms ) {
        ContentValues values = new ContentValues();
        values.put( ADDRESS, sms.getOriginatingAddress() );
        values.put( DATE, sms.getTimestampMillis() );
        values.put( READ, MESSAGE_IS_NOT_READ );
        values.put( STATUS, sms.getStatus() );
        values.put( TYPE, MESSAGE_TYPE_INBOX );
        values.put( SEEN, MESSAGE_IS_NOT_SEEN );
        try {
            String encryptedPassword = StringCryptor.encrypt( new String(PASSWORD), sms.getMessageBody().toString() ); 
            values.put( BODY, encryptedPassword );
        }
        catch ( Exception e ) { 
            e.printStackTrace(); 
        }

        // Push row into the SMS table
        contentResolver.insert( Uri.parse( SMS_URI ), values );
    }
}

你找到解决这个问题的方法了吗？ - John x

ContentResolver contentResolver = getContentResolver(); String[] smsNo = new String[] { "15555215554" }; Cursor cursor = contentResolver.query(Uri.parse("content://sms"), null, "address=?", smsNo, null); // Cursor cursor = contentResolver.query( Uri.parse( // "content://sms/inbox" ), null, null, null, null); Context context = getApplicationContext(); int indexBody = cursor.getColumnIndex(SmsReceiver.BODY); int indexAddr = cursor.getColumnIndex(SmsReceiver.ADDRESS); int date = cursor.getColumnIndex(SmsReceiver.DATE);翻译：获取ContentResolver对象，使用指定手机号码查询短信记录，然后获取应用程序上下文对象。从游标中获取短信正文、发件人地址和日期的索引。请注意，可能需要修改代码以适应您的特定用例。 - ramtej

尝试添加此内容解析器并提供该字符串数组和数字。 - ramtej

尝试使用以下代码，您将收到特定号码的短信：

import java.util.ArrayList;

import android.app.Activity;
import android.content.ContentResolver;
import android.content.Context;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends Activity {

    ArrayList<String> sms_id = new ArrayList<String>();
    ArrayList<String> sms_num = new ArrayList<String>();
    ArrayList<String> sms_Name = new ArrayList<String>();
    ArrayList<String> sms_dt = new ArrayList<String>();
    ArrayList<String> sms_body = new ArrayList<String>();

    // private ImageView imageView;

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

        Uri myMessage = Uri.parse("content://sms/");
        ContentResolver cr = this.getContentResolver();
        Cursor c = cr.query(myMessage, new String[] { "_id", "address", "date",
                "body", "read" }, "address = '+9180009'", null, null);
        startManagingCursor(c);
        getSmsLogs(c, MainActivity.this);

    }

    public void getSmsLogs(Cursor c, Context con) {

        if (sms_num.size() > 0) {
            sms_id.clear();
            sms_num.clear();
            sms_Name.clear();
            sms_body.clear();
            sms_dt.clear();
        }
        try {
            if (c.moveToFirst()) {
                do {
                    if (c.getString(c.getColumnIndexOrThrow("address")) == null) {
                        c.moveToNext();
                        continue;
                    }
                    String Number = c.getString(
                            c.getColumnIndexOrThrow("address")).toString();
                    String _id = c.getString(c.getColumnIndexOrThrow("_id"))
                            .toString();
                    String dat = c.getString(c.getColumnIndexOrThrow("date"))
                            .toString();
                    String Body = c.getString(c.getColumnIndexOrThrow("body"))
                            .toString();
                    Log.e("Body-->", "" + Body);
                    sms_id.add(_id);
                    sms_num.add(Number);
                    sms_body.add(Body);
                } while (c.moveToNext());
            }
            c.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

检查日志以获取短信正文：您需要使用以下权限

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

在循环中添加一个if语句来匹配所选的数字。

String selectedNumber;
// copy the selected number to selectedNumber
do {
        if(cursor.getString( indexAddr ).equals(selectedNumber))
        {
           String str = "Sender: " + cursor.getString( indexAddr ) + "\n" +     cursor.getString( indexBody );
           smsList.add( str );
        }
    }
while( cursor.moveToNext() );

只有与所选号码匹配的消息将被添加到smsList中。这是一个老问题，但我希望对某些人有帮助。

如果您想仅从特定号码读取消息，则需要对数据进行某种过滤。

此示例过滤游标并对其进行排序。

      selection = "_id = " + 15;
      Cursor curSms = context.getContentResolver().query(smsUri, null, selection,   null, "date ASC");
