setOnItemClickListener在定制列表视图

Question

下面是活动ShowData.java我在哪里设置自定义列表视图..现在我需要点击该列表视图查看，并且需要显示另一活动，但会抛出强制关闭。它在listview.setAdapter(adapter);

抛出错误

public class ShowData extends Activity 
{ 

    ListView listview; 
    Intent intent; 
    ArrayList<BeanClass> datalist; 
    CustomAdapter adapter; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 


     listview = (ListView) findViewById(R.id.listView1); 

     Intent intent = getIntent(); 
     datalist = (ArrayList<BeanClass>) intent.getSerializableExtra("list"); 
     Log.i("Size of ArrayList", "is " +datalist.size()); 

      adapter = new CustomAdapter(ShowData.this, R.layout.customrow , datalist); 

      listview.setAdapter(adapter); 
      listview.setOnItemClickListener(new OnItemClickListener() 
      { 
     @Override 
      public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) 
      { 
       Intent i = new Intent(ShowData.this,DetailActivity.class); 
       i.putExtra("datalist", datalist); 
       i.putExtra("position", arg2); 
       startActivity(i); 
      }    
} 
} 

这里是CustomAdapter.java

public class CustomAdapter extends ArrayAdapter<BeanClass> 
{ 
    Context context; 
    int layoutResourceId; 
    BeanClass bc; 
    ArrayList<BeanClass> vbc; 

    public CustomAdapter(Context context, int layoutResourceId, ArrayList<BeanClass> vbc) 
    { 
     super(context, layoutResourceId, vbc); 
     this.context=context; 
     this.layoutResourceId=layoutResourceId; 
     this.vbc=vbc; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) 
    { 
     View row = convertView; 
     StringReaderHolder holder; 

     if(row == null) 
     { 
      LayoutInflater inflater = ((Activity)context).getLayoutInflater(); 
      row = inflater.inflate(layoutResourceId, parent,false); 

      holder= new StringReaderHolder(); 


      holder.mytext1 = (TextView) row.findViewById(R.id.textView1); 
      holder.mytext2 = (TextView) row.findViewById(R.id.textView2); 
      holder.mytext3 = (TextView) row.findViewById(R.id.textView3); 

      row.setTag(holder); 
     } 
     else 
     { 
      holder = (StringReaderHolder) row.getTag(); 
     } 

     BeanClass bsObject = vbc.get(position); 

     holder.mytext1.setText(bsObject.name); 
     holder.mytext2.setText(bsObject.address); 
     holder.mytext3.setText(bsObject.phone); 


     return row; 
    } 

    static class StringReaderHolder 
    { 

     TextView mytext1,mytext2,mytext3; 

    } 

} 

我应该如何使用setOnItemClickListener ... ???谢谢...

在你的getView方法试试：

row.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       Intent i = new Intent(context,DetailActivity.class); 
       i.putExtra("datalist", vbc); 
       i.putExtra("position", position); 
       startActivity(i); 
      } 
     });
