Question

我正在隐藏一个具有特定employee_number的行，现在当我这样做时，正在跳过的行正在填充来自其前一行的数据。不知道怎么没有这个重复，只是跳过它？

CustomCursorWrapper.java：

public class CustomCursorWrapper extends CursorWrapper {

    private String mStartingEmployeeID = "startingNumber";
    Employee employee;


    public CustomCursorWrapper(Cursor cursor) {
        super(cursor);
    }

    @Override
    public int getCount() {

        //if you want to exclude just one row
        return super.getCount() - 1;
    }

    @Override
    public boolean moveToPosition(int position) {
        if(!super.moveToPosition(position))
            return false;

        if(mStartingEmployeeID.equals(getString(getColumnIndex("Employee_number")))) {
            //if this is the row you wanna skip
            return super.moveToPosition(position + 1);
        }
        Log.d("WRAPPER", String.valueOf(position));
        return true;
    }
}

另外，当我查看我放在这里的日志时，这些职位又回来了：

最好和最合适的解决方案是使用SQLite过滤器子句语句查询数据库以排除您不想要的行。这样，你就不必编写一堆黑客来跳过一行。

例如

getReadableDatabase().rawQuery("SELECT * FROM TABLE_NAME WHERE COLUMN != employeeId",null);

将返回一个光标，其中包含与传入的员工ID匹配的所有行。

跳过1时，CursorWrapper正在重复行
