获得光标字符串数组

问题描述

我有45个不同的条目的SQLite数据库，每个：

I have a SQLite Database with 45 different entries, each with:

public static final String TABLE = "Table";
public static final String COLUMN_ID = "_id";
public static final String COLUMN_HOUR = "hour";
public static final String COLUMN_WEEK = "week";
public static final String COLUMN_DAY = "day";
public static final String COLUMN_NAME = "name";
public static final String COLUMN_DESCRIPTION = "description";
public static final String COLUMN_COLOUR = "colour";
public static final String COLUMN_ROOM = "room";

现在我要读出所有。我这样做有以下内容：

now I want to read out all. I Do this with following:

public Cursor fetchAllSubject(){
    Cursor mCursor = database.query(true, TABLE, new String[] {
            COLUMN_ID, COLUMN_HOUR, COLUMN_WEEK, COLUMN_DAY, COLUMN_NAME, COLUMN_DESCRIPTION, COLUMN_COLOUR, COLUMN_ROOM},null
            , null, null, null, null, null);
    if (mCursor != null) {
        mCursor.moveToFirst();
    }
    return mCursor;
}

在一个其它的类我有这个code读全力以赴：

In a other class I have this code to read all out:

dao = new DAO(this);
Cursor subjectList = dao.fetchAllSubject();

现在我想为每个条目ID为一个数组，小时，星期，......但我不知道该怎么做。
我第一次尝试了以下内容：

Now I want to have for each entry an array with ID, Hour, week, ... but I have no idea how to do that.My first try was following:

ArrayList<String> mo1h = new ArrayList<String>();
subjectList.moveToFirst();
while(!subjectList.isAfterLast()) {
     mo1h.add(subjectList.getString(subjectList.getColumnIndex(dao.COLUMN_ID)));
     mo1h.add(subjectList.getString(subjectList.getColumnIndex(dao.COLUMN_HOUR)));
     mo1h.add(subjectList.getString(subjectList.getColumnIndex(dao.COLUMN_WEEK)));
     mo1h.add(subjectList.getString(subjectList.getColumnIndex(dao.COLUMN_DAY)));
     mo1h.add(subjectList.getString(subjectList.getColumnIndex(dao.COLUMN_NAME)));
     mo1h.add(subjectList.getString(subjectList.getColumnIndex(dao.COLUMN_DESCRIPTION)));
     mo1h.add(subjectList.getString(subjectList.getColumnIndex(dao.COLUMN_COLOUR)));
     mo1h.add(subjectList.getString(subjectList.getColumnIndex(dao.COLUMN_ROOM)));
     subjectList.moveToNext();
}

但一切都在mo1h，我不知道如何devide它。
最好的将是为每个一个String []。有任何人的想法？
谢谢！

But everything is in mo1h, and I dont know how to devide it.The best would be to have a String[] for each. Has anybody an Idea?Thanks!

推荐答案

您可以在创建的 Bean类，然后创建一个的ArrayList （集合类）

You can create on Bean class and then create one ArrayList (Collection class)

public class Bean
{
   public Bean();
   String id, hour, week, day, name, description, color, room;
}

现在创建的Bean列表

now create list of Bean

ArrayList<Bean> mo1h = new ArrayList<Bean>();
subjectList.moveToFirst();
while(!subjectList.isAfterLast()) {
Bean b = new Bean();
   b.id = subjectList.getString(subjectList.getColumnIndex(dao.COLUMN_ID));
   b.hour =subjectList.getString(subjectList.getColumnIndex(dao.COLUMN_HOUR));
   ...
   ...
   // all your column
   mo1h.add(b);
}
