自定义ArrayAdapter示例

主要步骤

1、编写ToDoItem类，重写其toString方法

2、写一个子类继承于ArrayAdapter<ToDoItem>重写其public View getView(int position, View convertView,ViewGroup parent)方法用于返回每一项的View

 

@Override
    public View getView(int position, View convertView,ViewGroup parent){
        LinearLayout todoView;
        ToDoItem item=getItem(position);
        String taskString=item.getTask();
        Date createDate=item.getCreated();
        SimpleDateFormat sdf=new SimpleDateFormat("dd/MM/yy");
        String dateString=sdf.format(createDate);
        if(convertView==null){//如果convertView为空则重新填充一下
            todoView=new LinearLayout(getContext());
            String inflater=Context.LAYOUT_INFLATER_SERVICE;
            LayoutInflater vi=(LayoutInflater)getContext().getSystemService(inflater);
            vi.inflate(resourceId, todoView, true);
        }else{
            todoView=(LinearLayout)convertView;
        }
        TextView dateView=(TextView)todoView.findViewById(R.id.rowDate);
        TextView taskView=(TextView)todoView.findViewById(R.id.row);
        dateView.setText(dateString);
        taskView.setText(taskString);
        
        return todoView;
    }
