Android ListView的长按事件

• 首先添加长按监听器。

//列表长按事件
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView parent, View view, int position, long id) {
                HashMap item = (HashMap)parent.getItemAtPosition(position);
                section =String.valueOf(item.get("name").toString());//get每-行的数据的名字
                selocate = String.valueOf(item.get("locate").toString());
                select_id = String.valueOf(item.get("id").toString());
                //Toast.makeText(InputActivity.this, ""+section, Toast.LENGTH_SHORT).show();

                selectedPosition = position;
                return false;
            }
        });

• 响应长按监听。

•  @Override
      public boolean onContextItemSelected(MenuItem item) {
          AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
          //info.id得到listview中选择的条目绑定的id
          String id = String.valueOf(info.id);
          switch (item.getItemId()) {
              case 0:
                  //删除事件
                  DBHelper dbHelper = new DBHelper();
                  dbHelper.open(this);                
                  dbHelper.deleteByName(section);
                  dbHelper.close();
                  list_data.remove(selectedPosition);
                  adapter.notifyDataSetChanged();
                  Toast.makeText(mContext, id + "已删除", Toast.LENGTH_SHORT).show();
                  return true;
              case 1:
                  Toast.makeText(mContext, id + "其他操作", Toast.LENGTH_SHORT).show();
                  return true;
              default:
                  return super.onContextItemSelected(item);
          }
      }
