自己做个笔记，方便以后的查阅，欢迎点评学习！

//声明ListView

private ListView lv_dept;

//加载ListView

lv_dept = (ListView) findViewById(R.id.lv_dept);

//设置Adapter

//depts 为实体类的list集合

lv_dept.setAdapter(new ListViewAdapter(this,depts));

//自定义的Adapter

class ListViewAdapter extends BaseAdapter{

    //布局加载器    LayoutInflater mInflater;

    //实体类集合    private  List<Depart> list;    //context    //list    public ListViewAdapter(Context context, List list) {        this.list=list;        mInflater = LayoutInflater.from(context);    }    @Override    public int getCount() {        return list.size();    }    @Override    public Object getItem(int position) {        return list.get(position);    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        ViewHolder viewHolder = null;        if (convertView==null){            viewHolder = new ViewHolder();

    //加载自定义的布局文件            convertView=mInflater.inflate(R.layout.dept_item,null);            viewHolder.txtId= (TextView) convertView.findViewById(R.id.tv_DeptId);            viewHolder.txtName= (TextView) convertView.findViewById(R.id.tv_DeptName);            convertView.setTag(viewHolder);        }else{            viewHolder = (ViewHolder) convertView.getTag();        }        viewHolder.txtId.setText(list.get(position).getAccessDeptId());        viewHolder.txtName.setText(list.get(position).getDeptName());        return convertView;    }}

//ViewHolder 自定义ViewHolder类class ViewHolder{    TextView txtId;    TextView txtName;}

仅供参考，欢迎指导！！！
