数据不是从android SQLite中检索的

Question

我正在尝试从toast信息中的数组列表中的sq lite数据库中检索数据，但显示

[util.AllProfileElement @ 4b0ae658，util.AllProfileElement @ 4b0a258c，...........]

喜欢我的数据保存在数据库中，我通过Toast消息确认请帮助我摆脱这个 enter code here

数据库助手类：

package database;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;

   public class DatabaseHeleper extends SQLiteOpenHelper{

// Database Name
private static final String DATABASE_NAME = "profile.db";
// All Static variables
// Database Version
private static final int DATABASE_VERSION = 1;
//table name
public static final String PROFILE_TABLE_NAME = "profile_table";

// Table Columns names
public static final String COL_PROFILE_ID = "id";
public static final String COL_PROFILE_NAME = "name";
public static final String COL_PROFILEE_GENDER = "gender";
public static final String COL_PROFILE_BLOOD = "blood";
public static final String COL_PROFILE_AGE= "age";
public static final String COL_PROFILE_HEIGHT= "height";
public static final String COL_PROFILE_WEIGHT = "weight";

// table information
private static final String DATABASE_PROFILE_TABLE = "create table "+ PROFILE_TABLE_NAME  + 
        "( " + COL_PROFILE_ID + " integer primary key autoincrement, " + " "

        + COL_PROFILE_HEIGHT + " text not null," + " "          
        + COL_PROFILE_WEIGHT + " text not null);";



public DatabaseHeleper(Context thiscontext) {
    // TODO Auto-generated constructor stub
    super(thiscontext, DATABASE_NAME, null, DATABASE_VERSION);

}
@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL(DATABASE_PROFILE_TABLE);     
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    Log.w(DatabaseHeleper.class.getName(),  "Upgrading database from version " + oldVersion + " to " + newVersion + ", which will destroy all old data");       
    db.execSQL("DROP TABLE IF EXISTS " + DATABASE_PROFILE_TABLE);       
    onCreate(db);
