android - SQLite アクセス テーブル コンテンツ

Question

次のクラスを使用してテーブルにデータを正常に挿入しましたが、それらのデータにアクセスする方法がわかりません。また、データテーブルとその列の内容を次のように配列リストに入れたい

column1--->array1
column1--->array2
column1--->array3
column1--->array4

public class SQLiteAdapter {

 public static final String MYDATABASE_NAME = "MY_DATABASE";
 public static final String MYDATABASE_TABLE = "MY_TABLE";
 public static final int MYDATABASE_VERSION = 1;
 public static final String KEY_ID = "_id";
 public static final String KEY_CONTENT1 = "Content1";
 public static final String KEY_CONTENT2 = "Content2";
 public static final String KEY_CONTENT3 = "Content3";
 public static final String KEY_CONTENT4 = "Content4";



 //create table MY_DATABASE (ID integer primary key, Content text not null);
 private static final String SCRIPT_CREATE_DATABASE =
  "create table " + MYDATABASE_TABLE + " ("
  + KEY_ID + " integer primary key autoincrement, "
  + KEY_CONTENT1 + " text not null, "
  + KEY_CONTENT2 + " text not null, "
  + KEY_CONTENT3 + " text not null, "
  + KEY_CONTENT4 + " text not null);";
