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;
}
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;
}
