如何使用 Gmail.java 读取对话

Question

我需要阅读 gmail 消息/对话来为盲人制作一个程序。 我正在使用 Gmail.java 访问 gmail 数据库。问题是我不知道如何访问邮件正文。

有人可以帮助我吗？

我的代码的一小段摘录：

Uri uri = Uri.parse( Gmail.AUTHORITY_PLUS_CONVERSATIONS + 帐户 + “/”); 光标cursorConversacion = contentResolver.query( uri，Gmail.CONVERSATION_PROJECTION，空，空，空）；

    int j = 1;
    //Comprobamos que hay cursor
    if (cursorConversacion.moveToFirst()){

        Gmail gmail = new Gmail(mContext.getContentResolver());
        ConversationCursor cc = new ConversationCursor(gmail,account,cursorConversacion);

        do{
            String cuenta = cc.getAccount();
            String snippet = cc.getFromSnippetInstructions();
            String subject = cc.getSubject();
            String numMessages = "" +  cc.getNumMessages();
            String conversationID = "" + cc.getConversationId();

            Log.d("DEBUG","\n\n\n MENSAJES " + j + " \n\n" + 
                    " ID: " + conversationID +
                    " Num messages: " + numMessages + 
                    " Subject: " + subject + 
                    "\nCuenta: " + cuenta +
                    " snippet: " + snippet


            );

            //MessageCursor a partir de la conversacion
            Uri uriMessages = Uri.parse(
                    Gmail.AUTHORITY_PLUS_CONVERSATIONS + account + "/" + conversationID + "/messages");
            Cursor cursorMessages = contentResolver.query(
                    uri, Gmail.MESSAGE_PROJECTION, null, null, null);


            if (cursorMessages.moveToFirst()){
                int k=1;
                do{
                    MessageCursor mc = new MessageCursor(gmail, contentResolver, account, cursorMessages);
                    Log.d("DEBUG","Mensaje " + k + " " + mc.getBody());

                    k++;
                }while ( (k < 10) && (cursorMessages.moveToNext()) ) ;

            }



            j++;
        }while ( (j< 20) && (cursorConversacion.moveToNext()) );

    }

问题是我不知道如何访问邮件正文。

对对话的访问有效，但 messageCursor 无效。我知道/相信 messageCursor 的使用不是用于消息（对话的消息），并且我知道使用未注释的提供程序是一个坏主意（如果您有更好的提供程序）我，拜托！！！）但这是我发现解决我的问题的更好的解决方案。

寻求帮助，抱歉我的英语。

public void getMails(Context mContext){
    String account="[email protected]";
    ContentResolver contentResolver= mContext.getContentResolver();
    Cursor cursor = contentResolver.query(ACCOUNT_URI, null, null, null, null);



    Uri uri = Uri.parse(
            Gmail.AUTHORITY_PLUS_CONVERSATIONS + account + "/");
    Cursor cursorConversacion = contentResolver.query(
            uri, Gmail.CONVERSATION_PROJECTION, null, null, null);

    int j = 1;
    //check cursor
    if (cursorConversacion.moveToFirst()){

        Gmail gmail = new Gmail(mContext.getContentResolver());
        ConversationCursor cc = new ConversationCursor(gmail,account,cursorConversacion);

        do{ //extract some data for the example
            String cuenta = cc.getAccount();
            String snippet = cc.getFromSnippetInstructions();
            String subject = cc.getSubject();
            String numMessages = "" +  cc.getNumMessages();
            String conversationID = "" + cc.getConversationId();

            Log.d("DEBUG","\n\n\n MENSAJES " + j + " \n\n" + 
                    " ID: " + conversationID +
                    " Num messages: " + numMessages + 
                    " Subject: " + subject + 
                    "\nCuenta: " + cuenta +
                    " snippet: " + snippet


            );


            MessageCursor mc = new Gmail(contentResolver).getMessageCursorForConversationId(account, cc.getConversationId());


            if (mc.getCursor().moveToFirst()){
                int k=1;
                do{
                    //MessageCursor mc = new MessageCursor(gmail, contentResolver, account, cursorMessages);
                    Log.d("DEBUG","Mensaje " + k + " " + mc.getBody());
                    Log.d("DEBUG",mc.getFromAddress());

                    k++;
                }while ( (k < 10) && (mc.next()) ) ;

            }



            j++;
        }while ( (j< 20) && (cursorConversacion.moveToNext()) );

    }

此代码使用 Gmail.java（我的问题帖子中的链接），它是提取电子邮件正文的示例。您可以提取其他属性，例如 mailFrom 或发送日期
