在SetAdapter後加上：registerForContextMenu(listView);// 上下文選單和listview結合的紐帶

然後實現長按事件：其中：menuInfo.position是獲取當前長按的是哪一項

 // 上下文的點選事件
 @Override
 public boolean onMenuItemSelected(int featureId, MenuItem item) {
  if (item.getMenuInfo() instanceof AdapterContextMenuInfo) {
   AdapterContextMenuInfo menuInfo = (AdapterContextMenuInfo) item
     .getMenuInfo();
   // 處理選單的點選事件
   switch (item.getItemId()) {
其中：menuInfo.position能獲取當前長按的item                                                                                          case 1:


    break;
   case 2:
    Toast.makeText(this, "檢視功能" + menuInfo.position,
      Toast.LENGTH_SHORT).show();
    break;
   case 3:
   
    break;
   case 4:
    Toast.makeText(this, "取消功能" + menuInfo.position,
      Toast.LENGTH_SHORT).show();
    break;
   }
  }
  return super.onContextItemSelected(item);
 }
