Android Gridview-Steuerelement und Schaltfläche OnItemclick

Hier ist mein buttonAdapter Klasse, dass ich denke richtig ist:

package com.example.test;

import android.content.Context; 
import android.graphics.Color; 
import android.view.View; 
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button; 
import android.widget.GridView;

public class ButtonAdapter extends BaseAdapter { 
    private Context mContext; 
    public String [] fName = { "File 1", "File 2", "Roflcopters"};

    //Gets the context so it can be used later 
    public ButtonAdapter(Context c) { mContext = c; }

    //Total number of things contained within the adapter 
    public int getCount () { return 8; }

    //Require for structure, not really used in my code. 
    public Object getItem (int position) {  return null; }

    //Require for structure, not really used in my code. Can be used to get the id of an item in the adapter for manual control. 
    public long getItemId (int position) { return position; }

    public View getView (int position, View convertView, ViewGroup parent){     
        Button btn;         
        if (convertView == null) {      //if it's not recycled, initialize some attributes      
            btn = new Button (mContext);
            btn.setLayoutParams (new GridView.LayoutParams (190, 190));
            btn.setPadding (1, 1, 1, 1);    
        } else {        
            btn = (Button) convertView;
        }       
      //btn.setText(filesnames[position]);   
      //filenames is an array of strings    
      //btn.setTextColor (Color.WHITE);
      //btn.setBackgroundResource (R.drawable.sample_2);  
      //btn.setBackgroundColor (Color.BLACK);     
      btn.setHighlightColor(Color.GREEN);    
      btn.setId (position);

      return btn; 
    } 
}

Hier ist mein Zuhause Klasse. Ich kann nicht Holen Sie sich die onItemClick zu erarbeiten. Was mache ich hier falsch:

package com.example.test;

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.View;
import android.view.View.OnClickListener; 
import android.widget.AdapterView; 
import android.widget.AdapterView.OnItemClickListener; 
import android.widget.GridView; 
import android.widget.Toast;

public class home extends Activity implements OnItemClickListener {

    public final static String EXTRA_MESSAGE1 = "com.example.text.MESSAGE";

    public void onCreate (Bundle savedInstanceState) {    
        super.onCreate(savedInstanceState);     
        setContentView (R.layout.activity_home);    

        GridView gridview = (GridView) findViewById (R.id.gridview);
        gridview.setAdapter (new ButtonAdapter (this));     

        /*gridview.setOnItemClickListener (new OnItemClickListener () {
           public void onItemClick (AdapterView <?> parent, View v, int position, long id) {          
            Toast.makeText (home.this, "" + position, Toast.LENGTH_LONG).show ();
            Intent intent = new Intent (this, alarm.class);       
            String message = "Position:" + position;            
            intent.putExtra(EXTRA_MESSAGE1, message);        
            startActivity (intent);         
            }     
        });   
     * */    
     }

    @Override 
    public void onItemClick (AdapterView <?> parent, View v, int position, long id) {  
        Intent intent = new Intent (this, alarm.class);
        String message = "Position:" + position;        
        intent.putExtra(EXTRA_MESSAGE1, message);        
        startActivity (intent);  
    }
}

Den onItemClick nicht funktioniert und auch nicht das kommentierte 'setOnItemClickListener', wenn es nicht auskommentiert und "onItemClick" ist kommentiert. Was mache ich falsch?
