Answer 1

您必须单独执行SQL以创建两个表。

private static final String DATABASE_CREATE1, DATABASE_CREATE2

DATABASE_CREATE1 = "CREATE TABLE " + MENAGE .........

DATABASE_CREATE2 = "CREATE TABLE " + Equipements_MENAGE .........

在Database Helper类中，您必须执行这些查询。

    public void onCreate(SQLiteDatabase db) throws SQLException {
        try {
            db.execSQL(ClassName.DATABASE_CREATE1);
            db.execSQL(ClassName.DATABASE_CREATE2);
        } catch (SQLException e) {
            Log.wtf("SQL ERROR", e.getMessage());
        }
    }
