Question

我想查询具有特定参考号+“ 0”或“ 3”的数据库。我的下面的代码返回奇怪的结果。什么是正确的查询方式？

        MyBaseVoyageFragment.java
        String broadcastTAG = BROADCAST_TAG + owner + String.valueOf(direction);
        if (intent != null) { // put the receiving data on intent
            Log.e("received", intent.getAction()); // succesfull action
            String intentAction = intent.getAction();
            if (intentAction.equals(broadcastTAG)) {

                parseIntentDataAndLoadVoyagesAdapter = new ParseIntentDataAndLoadVoyagesAdapter(intent);
                parseIntentDataAndLoadVoyagesAdapter.execute("");  // asenkron görevi çalıştır.
                //loadVoyagesToAdapter();
            } else if (intentAction.equals(BROADCAST_TAG + owner + "Error")) {
                showLoadingDialog(false);
                setErrorView(intent.getIntExtra("data", 0));
            }
        }

您说的是特定的参考编号+“ 1”或“ 3”。但是，当您编写选择查询时，此处传递的是“ 0”而不是“ 1”

 cursor = db.query(TABLE_PAPER, new String[] {KEY_PAPER_ID,
            KEY_PAPER_AMOUNT,
            KEY_PAPER_DATE,
            KEY_PAPER_REFERENCE,
            KEY_PAPER_PAID},KEY_PAPER_REFERENCE + "=?" + " AND " + KEY_PAPER_PAID + "=?" + " OR " + KEY_PAPER_PAID + "=?",
    new String[]{String.valueOf(rowId), "1", "3"},
    null, null, "date DESC");

您应在查询中传递“ 1”而不是“ 0”。
