Java 更新SQLITE数据库中的信息

我试图通过使用sqlitedatabase更新listview上的信息，因此在我的更新类中，我得到了一个错误，它出现在图片上

以下是dbhelper方法代码：

 public int updateInformation(String old_name, String new_name,String old_hours, String new_hours, String old_department,String new_department,SQLiteDatabase sqLiteDatabase) {

    ContentValues contentValues = new ContentValues();
    contentValues.put(UserContract.NewUserInfo.Name,new_name);
    contentValues.put(UserContract.NewUserInfo.RenderedHours,new_hours);
    contentValues.put(UserContract.NewUserInfo.Department,new_department);

    String selection = UserContract.NewUserInfo.Name + " LIKE ?";
    String[] selection_args = {old_name};
    int count = sqLiteDatabase.update(UserContract.NewUserInfo.TABLE_NAME,contentValues,selection,selection_args);
    return count;

}

更新类别代码：

  public void updateContact(View view) {

    userDBHelper = new UserDBHelper(getApplicationContext());
    sqLiteDatabase = userDBHelper.getWritableDatabase();
    String name,hours,department;

    name = new_name.getText().toString();
    hours = new_hours.getText().toString();
    department = new_department.getText().toString();
int count = userDBHelper.updateInformation(search_id,NewName,NewHours,NewDepartment,sqLiteDatabase);

}
}

编辑：我将代码更改为：

public void updateContact(View view) {

    userDBHelper = new UserDBHelper(getApplicationContext());
    sqLiteDatabase = userDBHelper.getWritableDatabase();
    String name,hours,department;

    name = new_name.getText().toString();
    hours = new_hours.getText().toString();
    department = new_department.getText().toString();
    int count =  userDBHelper.updateInformation(search,name,hours,department,sqLiteDatabase);

}

 int count = userDBHelper.updateInformation(search_id,name,hours,department,sqLiteDatabase);

public int updateInformation(String old_name, String new_name, String new_hours,String new_department,SQLiteDatabase sqLiteDatabase)

我还是会犯错误，我不明白

第二次编辑：我现在明白了好吧，我只是错误地输入了更新联系人所需的字符串和参数，我将代码替换为：

public void updateContact(View view) {

    userDBHelper = new UserDBHelper(getApplicationContext());
    sqLiteDatabase = userDBHelper.getWritableDatabase();
    String name,hours,department;

    name = new_name.getText().toString();
    hours = new_hours.getText().toString();
    department = new_department.getText().toString();
    int count =  userDBHelper.updateInformation(search,name,hours,department,sqLiteDatabase);

}

 int count = userDBHelper.updateInformation(search_id,name,hours,department,sqLiteDatabase);

public int updateInformation(String old_name, String new_name, String new_hours,String new_department,SQLiteDatabase sqLiteDatabase)

DBHelper.updateInformation代码：

public int updateInformation(String old_name, String new_name, String new_hours,String new_department,SQLiteDatabase sqLiteDatabase)

我现在知道了，我的参数不匹配，我通过将代码更改为：

public void updateContact(View view) {

    userDBHelper = new UserDBHelper(getApplicationContext());
    sqLiteDatabase = userDBHelper.getWritableDatabase();
    String name,hours,department;

    name = new_name.getText().toString();
    hours = new_hours.getText().toString();
    department = new_department.getText().toString();
    int count =  userDBHelper.updateInformation(search,name,hours,department,sqLiteDatabase);

}

 int count = userDBHelper.updateInformation(search_id,name,hours,department,sqLiteDatabase);

public int updateInformation(String old_name, String new_name, String new_hours,String new_department,SQLiteDatabase sqLiteDatabase)

然后更改更新类中的代码：

int count = userDBHelper.updateInformation(search_id,name,hours,department,sqLiteDatabase);

数一数你的参数，你应该能够弄明白这一点。IDE会告诉你到底是怎么回事。你的两个参数：String old_department、String new_department丢失了，而且你在函数中添加了edittext而不是String check函数。实际上函数有七个参数，但你只传递了五个参数。我现在得到了，谢谢
