Android片段列表和GridView

我尝试在蜂巢中创建两个片段，列表和gridview。当我单击列表项时，gridview成功显示。但是，列表消失了。gridview应该显示在列表旁边。以下是我的代码：

FragmentTestActivity.java

package com.android.tabgrid;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class FragmentTestActivity extends FragmentActivity implements
OnItemClickListener {          

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ListView lv = (ListView)findViewById(R.id.list_icon);
    ArrayAdapter<String> yoyo = new ArrayAdapter<String>(getApplicationContext(),
            android.R.layout.simple_list_item_1,new String[] {
        "Traffic",
        "Forum",
        "Promo",
        "Others"
    });
    lv.setAdapter(yoyo);
    lv.setOnItemClickListener(this);
}


@Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
    // TODO Auto-generated method stub
    Fragment f = new TestFragment(position+1);

    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    ft.replace(R.id.the_frag,f);
    ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
    ft.addToBackStack(null);
    ft.commit();

}
}

GridView1.java

package com.android.content;

import com.android.tabgrid.FragmentTestActivity;
import com.android.tabgrid.R;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import com.android.tabgrid.TestFragment;

public class GridView1 extends FragmentActivity{

Integer[] img = {
    R.drawable.btn_spot_u,
    R.drawable.btn_traffic_u,
    R.drawable.btn_forum_u,
    R.drawable.btn_promo_u
};

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.content_1);

    GridView gV = (GridView)findViewById(R.id.grid1);
    gV.setAdapter(new ImageAdapter(this));

}

public class ImageAdapter extends BaseAdapter {

    private Context ctx;

    public ImageAdapter(Context c) {
        ctx = c;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return img.length;
    }

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

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

    @Override
    public View getView(int position, View v, ViewGroup parent) {
        // TODO Auto-generated method stub
        ImageView imgView;
        if(v == null) {
            imgView = new ImageView(ctx);
            imgView.setLayoutParams(new GridView.LayoutParams(85,85));
            imgView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imgView.setPadding(5, 5, 5, 5);
        } else {
            imgView = (ImageView) v;
        }
        imgView.setImageResource(img[position]);
        return imgView;
        }   
        }
        }
