Android SQLite 多表输入

Question

我有一个预算程序，它使用多个表来存储信息。当我尝试一次向多个表添加信息时，我最终只让第一个表接收任何信息。这是我使用的代码：

public SQLiteDatabase createBudget(String bname, String bpay, String bamount,
                String bmemo) {
            // TODO Auto-generated method stub
            ContentValues t1 = new ContentValues();
            ContentValues t2 = new ContentValues();
            ContentValues t4 = new ContentValues();
            t1.put(KEY_NAME, bname);
            t1.put(KEY_PAYDAY,bpay);
            t2.put(KEY_AMOUNT, bamount);
            t4.put(KEY_MEMO, bmemo);
            ourDatabase.insert(DATABASE_TABLE1, null, t1);
            ourDatabase.insert(DATABASE_TABLE2, null, t2);
            ourDatabase.insert(DATABASE_TABLE4, null, t4);
            return ourDatabase;
        }

我完全不知道该怎么做。我曾尝试在网上查找，但我发现的内容是针对单表数据库的。我将不胜感激任何帮助。这是 LogCat 内容：

Answer 1

我认为问题是“Budget_Items.edit_date 可能不是 NULL”。您的数据库中有一个 NOT NULL 列，并尝试在 Budget_Items.edit_date 列中插入一行而不给出值

Answer 2

你的约束异常在这里非常明显

android.database.sqlite.SQLiteConstraintException：Budget_Items.edit_date 不能为 NULL（代码 19）

尝试在您的调用周围放置一个 try catch 块以找出确切的错误。
