نحوه گرفتن مقدار دیتابیس در اکتیویتی علاقه مندی ها(لطفا کمک کنید)

دوستان با چه کدی باید در اکتیویتی علاقمندی مقدار ذخیره شده دیتابیس رو فراخوانی کنم ؟

این اکتیویتی لیست ویو هست:

 package com.nemone.favoritelist;

import android.os.Bundle;
import android.util.Log;
import android.app.Activity;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.widget.Adapter;
import android.widget.ListView;

public class MainActivity extends Activity {

	private MyDatabase MyDatabase;
	public ListView listview;
	SQLiteDatabase mydb;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		MyDatabase = new MyDatabase(this);
		mydb = MyDatabase.getReadableDatabase();
		Cursor c = mydb.rawQuery("select id,name,category,like from list", null);
		int ids[] = new int[c.getCount()];
		String names[] = new String[c.getCount()];
		String cats[] = new String[c.getCount()];
		String likes[] = new String[c.getCount()];
		int i = 0;
		if(c.moveToFirst()) {
			do {
				ids[i] = c.getInt(0);
				names[i] = c.getString(1);
				cats[i] = c.getString(2);
				likes[i] = c.getString(3);
				i++;
			} while (c.moveToNext());
			c.close();
			mydb.close();
		}
		
		listview = (ListView) findViewById(R.id.listView1);
		MyAdapter adapter = new MyAdapter(this, names, cats, likes, ids);
		listview.setAdapter(adapter);
	}

}

اینم اکتیویتی myadapter:


package com.nemone.favoritelist;

import android.app.Activity;
import android.database.sqlite.SQLiteDatabase;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.TextView;

public class MyAdapter extends ArrayAdapter<String>{
	
	private final Activity context;
	String names[];
	String cats[];
	String likes[];
	int ids[];
	
	public MyAdapter(Activity context,String names[], String cats[], String likes[], int ids[]) {	
		super(context, R.layout.item, names);
		this.context = context;
		this.names = names;
		this.cats = cats;
		this.likes = likes;
		this.ids = ids;
	}

	@Override
	public boolean isEnabled(int position) {
		// TODO Auto-generated method stub
		return true;
	}

	@Override
	public View getView(final int position, View view, ViewGroup parent) {
	
		LayoutInflater inflater = context.getLayoutInflater();
		View rowView = inflater.inflate(R.layout.item, null, true);
		TextView txtName = (TextView) rowView.findViewById(R.id.txt_name);
		TextView txtCat = (TextView) rowView.findViewById(R.id.txt_numer);
		CheckBox favotite = (CheckBox) rowView.findViewById(R.id.favorite_check);
		txtName.setText(names[position]);
		txtCat.setText(cats[position]);
		if(likes[position].equals("no")) {
			favotite.setChecked(false);
		} else if (likes[position].equals("yes")) {
			favotite.setChecked(true);
		}
		Log.i("tag", "likes :"+likes[position]);
		favotite.setOnCheckedChangeListener(new OnCheckedChangeListener() {
			
			@Override
			public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
				// TODO Auto-generated method stub
				MyDatabase MyDatabase = new MyDatabase(context);
				SQLiteDatabase mydb = MyDatabase.getWritableDatabase();
				if(isChecked == true) {
					mydb.execSQL("update list set like = 'yes' where id = " + ids[position]);
				} else {
					mydb.execSQL("update list set like = 'no' where id = " + ids[position]);
				}
				mydb.close();
			}
		});
			
		return rowView;
	}
