Java 通过xml资源中包含的数组初始化sqlite表

我必须在android中初始化sqllite数据库。 以下是表格的结构：

    public static abstract class FeedEntry implements BaseColumns {
    public static final String TABLE_NAME = "entry";
    public static final String COLUMN_NAME_ENTRY_ID = "entryid";
    public static final String COLUMN_NAME_TITLE = "title";
}

String[] projection = {
            FeedReaderContract.FeedEntry._ID,
            FeedReaderContract.FeedEntry.COLUMN_NAME_TITLE,
    };
Cursor cursor = db.query(
            FeedReaderContract.FeedEntry.TABLE_NAME,  // The table to query
            projection,                               // The columns to return
            null,                                // The columns for the WHERE clause
            null,                            // The values for the WHERE clause
            null,                                     // don't group the rows
            null,                                    // don't filter by row groups
            sortOrder 


);


String result = "";

    DatabaseUtils.dumpCursor(cursor);
    int iRow = cursor.getColumnIndex(FeedReaderContract.FeedEntry._ID);
    int iName = cursor.getColumnIndex(FeedReaderContract.FeedEntry.COLUMN_NAME_TITLE); 
        for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()){
        result = result + cursor.getString(iRow) + " " + cursor.getString(iName) + "\n";
    }
    System.out.println(result);

我有一个array.xml文件，如下所示：

<?xml version="1.0" encoding="utf-8"?>

1 1
2 1
3 1
4 1

问题是没有得到预期的结果

S1 999 
S1 10 
S1 111 
S1 101

我得到以下信息：

<?xml version="1.0" encoding="utf-8"?>

1 1
2 1
3 1
4 1

实际上，

System.out.println（item）打印的每个项目

由一对两个值组成，如

11、21

等。我应该如何修改onCreate的java方法以获得正确的字符串对，比如

s1999

以下是我如何读取表中的数据：

    public static abstract class FeedEntry implements BaseColumns {
    public static final String TABLE_NAME = "entry";
    public static final String COLUMN_NAME_ENTRY_ID = "entryid";
    public static final String COLUMN_NAME_TITLE = "title";
}

String[] projection = {
            FeedReaderContract.FeedEntry._ID,
            FeedReaderContract.FeedEntry.COLUMN_NAME_TITLE,
    };
Cursor cursor = db.query(
            FeedReaderContract.FeedEntry.TABLE_NAME,  // The table to query
            projection,                               // The columns to return
            null,                                // The columns for the WHERE clause
            null,                            // The values for the WHERE clause
            null,                                     // don't group the rows
            null,                                    // don't filter by row groups
            sortOrder 


);


String result = "";

    DatabaseUtils.dumpCursor(cursor);
    int iRow = cursor.getColumnIndex(FeedReaderContract.FeedEntry._ID);
    int iName = cursor.getColumnIndex(FeedReaderContract.FeedEntry.COLUMN_NAME_TITLE); 
        for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()){
        result = result + cursor.getString(iRow) + " " + cursor.getString(iName) + "\n";
    }
    System.out.println(result);

：我有一个向数据库发送请求的游标，然后我打印游标的内容。

您的字符串拆分错误。要按空格分割字符串，请使用以下代码

str = "This is the string seperated by space";
String[] splited = str.split("\\s+");

@这是个小问题，谢谢。但是，我仍然存在错误输出的主要问题..制作ArrayList并逐个添加元素并检查。如何获取数据并打印它？邮政编码。@Rahul我添加了更多解释。。。
