我已经用新的错误更改了日志猫.Log-cat错误再次显示相同的错误，并且在日历中单击日期后模拟器强制关闭... 我甚至在清单中声明了所有活动然后错误继续.... 请帮忙

我添加了项目的完整代码，请验证代码。从gridview调用新xml布局的onclick事件显示错误。
要查看日历，这里是代码。

month.set(Integer.parseInt(dateArr[0]), Integer.parseInt(dateArr[1]), Integer.parseInt(dateArr[2]));
}
public Runnable calendarUpdater = new Runnable() {
@Override

// format random values. You can implement a dedicated class to provide real values

if(r.nextInt(10)>6)
{

android.content.ActivityNotFoundException: Unable to find explicit activity class {com.examples.android.calendar/android.util.EventLog$Event}; have you declared this activity in your AndroidManifest.xml?
您可以打开另一个活动onItemclick gridview。您的logcat显示您忘记在清单文件中注册您的活动。确保您已在清单文件中声明了您的活动。
<强>编辑：
您正在重定向到Event上的onItemClicklistener班级，并且您尚未在清单文件中声明您的Event活动。在您的清单文件中声明它。
<application android:icon="@drawable/icon"

同时删除已在清单中声明的Adapter类。 <activity android:name="com.examples.android.calendar.CalendarAdapter"> </activity>适配器永远不会在清单中声明。

即使您已经抵制，也要尝试以正确的方式放置，
我认为您已在申请标记之外宣布您的活动。
我认为它会起作用..

你有“android.content.ActivityNotFoundException”异常......这意味着你没有把你的活动放在清单中......
