这里我可以在点击特定日期时查看所有事件，但我的要求也是显示带有粗体样式的日期或包含事件而没有单击gridview项目的任何其他颜色视图。我的适配器类如下::: < / p>

答案 0 :(得分：0)
Atlast我已经解决了我的问题，更改了我的Runnable日历更新程序，如下所示：
public Runnable calendarUpdater = new Runnable() {
@Override
public void run()
{
items.clear();
// Print dates of the current week
DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
String itemvalue;
for (int i = 0; i < 7; i++)
{
itemvalue = df.format(itemmonth.getTime());
itemmonth.add(Calendar.DATE, 1);
items.add("2014-12-08");
items.add("2014-12-04");
items.add("2014-11-07");
items.add("2014-11-08");
}
adapter.setItems(items);
adapter.notifyDataSetChanged();
}
};
现在我可以在不点击gridView项目的情况下看到这些事件。感谢所有人在这方面的友好合作。但现在问题是如何在Android谷歌日历上显示此事件。
