使用片段和gridview android添加到收藏夹问题

Question

所以我的ViewPager上有Save to Favorite和HomeFragment按钮。当我点击按钮时，我想要存储图像，然后在另一个片段上检索，我使用FavGridAdapter。我尝试使用getter / setter作为位置，但它不起作用。以下是HomeFragment，FavGridAdapter和FavList（getter / setter）的代码。

HomeFragment

import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.List;

import android.app.Fragment;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.support.v4.view.ViewPager.OnPageChangeListener;
import android.support.v4.view.ViewPager.SimpleOnPageChangeListener;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;

public class HomeFragment extends Fragment {

private static int currentPage;
ViewPager viewPager;

public static HomeFragment newInstance() {
    return new HomeFragment();
}

public HomeFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_home, container,
            false);

    /*
     * ImageButton ib = (ImageButton) rootView.findViewById(R.id.buttonEnq);
     * ib.setOnClickListener(new OnClickListener() {
     * 
     * @Override public void onClick(View v) { InfoFragment infoFragment =
     * new InfoFragment(); //FragmentManager fm = getFragmentManager();
     * //fm.beginTransaction().replace(R.id.frame_container,
     * infoFragment).commit();
     * 
     * FragmentTransaction ft = getFragmentManager().beginTransaction();
     * //ft.setCustomAnimations(R.anim.abc_slide_out_bottom, 0);
     * ft.addToBackStack(null);
     * ft.replace(R.id.frame_container,infoFragment); ft.commit(); } });
     */

    viewPager = (ViewPager) rootView.findViewById(R.id.myfivepanelpager);
    ImageAdapter adapter1 = new ImageAdapter(this.getActivity());
    viewPager.setAdapter(adapter1);

    Button buttonFav = (Button)rootView.findViewById(R.id.buttonFav);
    buttonFav.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            int position = viewPager.getCurrentItem();

            //List<FavList> fav = new ArrayList<FavList>();
            FavList item=new FavList();
            item.setPosition(position);
            Log.e("error", "item:" +item);
            //fav.add(item);

            /*CommunityFragment fragment  = new CommunityFragment();
            Bundle bundle = new Bundle();
            bundle.putLong("position", position);
            Log.e("error", "bundle:"+bundle.toString());
            fragment.setArguments(bundle);*/
        }
    });

    return rootView;
}

@Override
public void onDetach() {
    super.onDetach();

    try {

        Field childFragmentManager = Fragment.class
                .getDeclaredField("mChildFragmentManager");
        childFragmentManager.setAccessible(true);
        childFragmentManager.set(this, null);

    } catch (NoSuchFieldException e) {
        throw new RuntimeException(e);
    } catch (IllegalAccessException e) {
        throw new RuntimeException(e);
    }
}
}

FavGridAdapter

import android.content.Context;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;

public class FavGridAdapter extends BaseAdapter {

private Context context;
int position1;

public FavGridAdapter(Context c,int position) {
    context = c;
    this.position1=position;
}

@Override
public int getCount() {
    return GalImages.length;
}

@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView;
    if (convertView == null) {
        imageView = new ImageView(context);
        imageView.setLayoutParams(new GridView.LayoutParams(300, 300));
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setPadding(0, 0, 0, 0);
    } else {
        imageView = (ImageView) convertView;
    }

    FavList item = new FavList();
    int i = item.getPosition();

    Log.e("error", "getpos:"+i);
    imageView.setImageResource(GalImages[i]);
    return imageView;
}

private int[] GalImages = new int[] { R.drawable.gw12, R.drawable.gw1,
        R.drawable.gw2, R.drawable.gw3, R.drawable.gw4, R.drawable.gw5,
        R.drawable.gw6, R.drawable.gw7, R.drawable.gw8, R.drawable.gw9,
        R.drawable.gw11, R.drawable.gw81 };
}

FavList

public class FavList {

int position;

public int getPosition() {
    return position;
}

public void setPosition(int position) {
    this.position = position;
}

public FavList() {
};



}

这是正确的方法吗？如果有其他技巧请告诉我。谢谢。
