我正在网格视图中制作日历,并通过R.layout.screen_gridcell
.
日历正常膨胀,但我想添加一个进一步的功能,当用户按下一天时,按下的单元格将使用drawable
calendar_tile_chosen
.
但是当我按下任何单元格时什么都没有发生。
问题:
onClick
当我可以应用效果时,如何取回所选网格单元按钮的 iddrawable
calendar_tile_chosen
?- 由于用户可能会在 day1 之后点击另一天(day2),当按下 day2 时,如何将 day1 设置回正常布局?在将可绘制的 calendar_tile_chosen 应用于第 2 天之前,需要记住第 1 天并刷新整个日历吗?这条路线似乎很笨拙..
查看getView:
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
View row = convertView;
if (row == null)
{
LayoutInflater inflater = (LayoutInflater) _context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.screen_gridcell, parent, false);
}
// Get a reference to the Day gridcell
gridcell = (Button) row.findViewById(R.id.calendar_day_gridcell);
gridcell.setOnClickListener(this);
gridcell.setTag(theday + "-" + themonth + "-" + theyear);
点击:
@Override
public void onClick(View view)
{
String date_month_year = (String) view.getTag();
gridcell.setBackgroundResource(R.drawable.calendar_tile_chosen);
