android - Android短信，按其线程ID分组

我正在实施一个SMS应用程序，到现在为止我已经实现了获取所有消息（发送，接收，草稿）及其联系电话，线程ID，联系电话ID，日期，类型。

这是我的代码：

Uri mSmsinboxQueryUri = Uri.parse("content://sms");
        Cursor cursor = _context.getContentResolver().query(
                mSmsinboxQueryUri,
                new String[] { "_id", "thread_id", "address", "date", "body",
                        "type" }, null, null, null);

        String[] columns = new String[] { "address", "thread_id", "date",
                "body", "type" };
        if (cursor.getCount() > 0) {

            while (cursor.moveToNext()) {

                String address = null, date = null, msg = null, type = null, threadId = null;

                address = cursor.getString(cursor.getColumnIndex(columns[0]));
                threadId = cursor.getString(cursor.getColumnIndex(columns[1]));
                date = cursor.getString(cursor.getColumnIndex(columns[2]));
                msg = cursor.getString(cursor.getColumnIndex(columns[3]));
                type = cursor.getString(cursor.getColumnIndex(columns[4]));

                Log.e("SMS-inbox", "\nTHREAD_ID: "
                        + threadId + "\nNUMBER: " + address + "\nTIME: " + date + "\nMESSAGE: " + msg + "\nTYPE: " + type);
            }
        }
    }

现在，我需要按线程ID（具有相同线程ID的消息）分隔这些消息。我怎样才能最好地做到这一点？谢谢！

最佳答案

首先，我不会单独保存这些字符串。

我要做的是一个像这样的课：

public class SmsMsg {
    private String address = null;
    private String threadId = null;
    private String date = null;
    private String msg = null;
    private String type = null;

    //c'tor
    public SmsMsg(Cursor cursor) {
       this.address = cursor.getString(cursor.getColumnIndex("address"));
       this.threadId = cursor.getString(cursor.getColumnIndex("thread_id"));
       this.date = cursor.getString(cursor.getColumnIndex("date"));
       this.msg = cursor.getString(cursor.getColumnIndex("body"));
       this.type = cursor.getString(cursor.getColumnIndex("type"));
    }
}

现在，只要SmsMsg是cursor.moveToNext()，就可以在while循环中实例化true的对象，并将其添加到您选择的List中。

现在，您可以将所需threadId的所有消息复制到其他List并按日期对它进行排序。这取决于您要使用它做什么。
