java - 方法 updateGames 类中的 GamesActivity 不能为 App

转载作者：行者123 更新时间：2023-12-02 11:13:59

我正在尝试使用对话框中的一些附加 EditText 字段更新 SQLite 数据库表。我如何在更新游戏表的所有五行中收到以下错误消息。

错误:GamesActivity 类中的方法 updateGames 无法应用错误:GamesActivity 类中的 updateGames 方法无法应用于给定类型；必需:int,int,int,int,int,int,int,String发现:字符串，整数原因:实际参数列表和形式参数列表的长度不同

我知道我很可能错误地为 updateGame 方法创建了参数。由于我对 Javascript 和 Android 编程相当陌生，我似乎找不到纠正这个问题的方法。当我查看 DatabaseHelper 时，我可以看到该方法从未被调用或使用。我假设这是因为我的论点是错误的。

我在下面列出了我的代码。如果有人能看一下并指出我做错了什么，我将不胜感激。

最佳答案

我看起来你应该更换:-

        updateGames(inputScore.getText().toString(), position);
        updateGames(inputStrikes.getText().toString(), position);
        updateGames(inputSpares.getText().toString(), position);
        updateGames(inputSplits.getText().toString(), position);
        updateGames(inputSplitConversions.getText().toString(), position);
        updateGames(inputOpenFrames.getText().toString(), position);

与:-

        updateGames(
            Integer.parseInt(inputScore.getText().toString()),
            Integer.parseInt(inputScore.getText().toString()),
            Integer.parseInt(inputSpares.getText().toString()),
            Integer.parseInt(inputSplits.getText().toString()),
            Integer.parseInt(inputSplitConversions.getText().toString()),
            Integer.parseInt(inputOpenFrames.getText().toString()),
            position, 
            String.valueOf(System.currentTimeMillis()) //<<<<< FORMAT GUESSED
        );

这将适合 updateGames 方法的签名，即:-

    private void updateGames(
            int score, 
            int strikes, 
            int spares, 
            int splits, 
            int splitconversions, 
            int openframes, 
            int position, 
            String timestamp) {

        Games n = gamesList.get(position);
        n.setScore(score);
        n.setStrikes(strikes);
        n.setSpares(spares);
        n.setSplits(splits);
        n.setSplitConversions(splitconversions);
        n.setOpenFrames(openframes);
        n.setTimestamp(timestamp);
        db.updateGames(n);
        gamesList.set(position, n);
        mAdapter.notifyItemChanged(position);
        toggleEmptyGames();
    }

它使用db.updateGames(n);来更新数据库。
如果 EditText 中的值不正确(例如它们必须仅为数字)，那么您将收到解析异常。
注意您可能需要调整时间戳的格式以适应。
此外这是原则上的代码，尚未经过测试。
