Je pense que vous utilisez CustomAdapter pour alimenter le ListView ..

Si oui, alors dans getView() inclut l'action du bouton:

public View getView(final int position, View convertView, ViewGroup parent) 
        { 

          View row=convertView; 
          FetchHolder holder=null; 

          if (row==null) 
          { 
          LayoutInflater inflater=getLayoutInflater(); 
          row=inflater.inflate(R.layout.grid, parent, false); 

          holder=new FetchHolder(row); 


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

          holder.button.setOnClickListener(new OnClickListener() 
          { 
           public void onClick(View v) { 

           } 
          }); 
          return row; 
          } 

         } 



        static class FetchHolder 
        { 
         private Button time=null; 

         FetchHolder(View row) 
         { 

          time=(Button)row.findViewById(R.id.timebutton); 

           }
