Android 从收件箱搜索邮件未成功

我希望根据特定的号码从收件箱中获取有关邮件的信息。我正在使用以下代码来实现此目标，但未按预期方式工作：

public void SendTheSmsToTheFolder(String NameOfContact,String Number,String FolderAddress,long TimeLimit)
    {
        m_NameOfContact = NameOfContact;
        String SMS_URI_INBOX = "content://sms/inbox"; 
        Uri l_uri = Uri.parse(SMS_URI_INBOX); 

        Cursor l_SendTheSmsToTheFolderCursor = getContentResolver().query(l_uri, null, "address=?",new         String[]{Number.trim()},null);
        if (l_SendTheSmsToTheFolderCursor.moveToFirst())
        {  
            int l_index_Address = l_SendTheSmsToTheFolderCursor.getColumnIndex("address");  
            int l_index_Person = l_SendTheSmsToTheFolderCursor.getColumnIndex("person");  
            int l_index_Body = l_SendTheSmsToTheFolderCursor.getColumnIndex("body");  
            int l_index_Date = l_SendTheSmsToTheFolderCursor.getColumnIndex("date");  
            do 
            {  
                String l_strAddress = l_SendTheSmsToTheFolderCursor.getString(l_index_Address);  
                String l_strbody = l_SendTheSmsToTheFolderCursor.getString(l_index_Body);  
                long l_longDate = l_SendTheSmsToTheFolderCursor.getLong(l_index_Date);  

                Log.v("Message: ","Body of the message is "+l_strbody);
            } while (l_SendTheSmsToTheFolderCursor.moveToNext());  
        }
}

我很确定盒子里有这个电话号码的信息，我已经核对过这个事实。但是，我的光标计数始终显示为0。我不知道问题出在哪里。我搜索了很多次，但无法找到答案。请帮助我。提前感谢。

如果您想搜索特定号码的邮件，可以尝试此代码

 Uri uri = Uri.parse("content://sms/inbox");
    ContentResolver contentResolver = context.getContentResolver();
    String where = "address="+ phNum; //here you can use that particular number
    Cursor cursor = contentResolver.query(uri, new String[] { "_id", "thread_id"}, where, null,null);

这对我很有效。让我知道它是否解决了你的问题
