Java文件

 public class MainActivity extends ListActivity implements OnItemClickListener
{       
    int ht,wt;
ListView list;
    DataHelperCoverLetter dbcl;
    ArrayList<String> coverLetterTitle = new ArrayList<String>();

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {   
        super.onCreate(savedInstanceState);
        setContentView(R.layout.coverletterselection);      

        dbcl = new DataHelperCoverLetter(this);
        DisplayMetrics displaymetrics = new DisplayMetrics();       
        getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);      
        ht = displaymetrics.heightPixels;      
        wt = displaymetrics.widthPixels;
        bg = (ImageView)findViewById(R.id.coverletterbgView);
        bg.setLayoutParams(new LinearLayout.LayoutParams(wt, ht/3));    

        coverLetterTitle = dbcl.fetchCoverLetter();

            //get the listView from your layout and define the listener on it
            list = (ListView)findViewById(R.id.list);
            list.setOnItemClickListener(this);

        addCoverLetterBtn = (ImageButton)findViewById(R.id.addCoverLetter);
        addCoverLetterBtn.setOnClickListener(this);
        setListAdapter(new CoverLetterAdaptor(this,ht,wt,coverLetterTitle));        
    }
    @Override
    public void onListItemClick(ListView parent, View view, int position, long id)
    {     
        Log.i("OnClick", "position = "+position);

    }   
}


public class CoverLetterAdaptor extends BaseAdapter
{
    private LayoutInflater mInflater;   
    ArrayList<String> coverLetterItems;
    Context context;    
    int ht,wt;  

    public CoverLetterAdaptor(Context context,int ht,int wt,ArrayList<String> coverLetterItems)
    {
        this.context = context;
        this.coverLetterItems = new ArrayList<String>();
        this.coverLetterItems = coverLetterItems ;          
        this.ht = ht;
        this.wt = wt;
        mInflater = LayoutInflater.from(context);   
    }

    public int getCount() {
        return coverLetterItems.size();
    }

    public Object getItem(int position) {
        return position;
    }

    public long getItemId(int position) {
        return position;
    }


    public View getView(int position, View convertView, ViewGroup parent)
    {       
        ViewHolder holder;

        convertView = mInflater.inflate(R.layout.coverletteradaptor, null);     
        holder = new ViewHolder();

        holder.coverLetterTxt = (TextView) convertView.findViewById(R.id.coverLetterAdaptorTxt);
        holder.bgImageCCAdaptor = (ImageView)convertView.findViewById(R.id.bgimageCoverLetter);
        holder.bgImageCCAdaptor.setLayoutParams(new RelativeLayout.LayoutParams(wt, ht/7));     

        convertView.setTag(holder);
        holder = (ViewHolder) convertView.getTag();
        holder.coverLetterTxt.setText(coverLetterItems.get(position));                          
        return convertView;
    }

    static class ViewHolder 
    {
        TextView coverLetterTxt;        
        ImageView bgImageCCAdaptor;
    }
}

我想你忘记了 setOnItemClickListener

ListView lst = (ListView) findViewById(R.id.list);
        lst.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int position,
                    long arg3) {
                // TODO Auto-generated method stub
                Log.i("OnClick", "position = " + position);
            }
        });

在您的代码中添加这一行...
