我正在使用 android 为工作门户开发移动应用程序，因为我有列表视图，我在列表视图日期列中使用了图像视图，我的要求是如果我单击图像视图，则自动添加日历事件。下面是我使用的代码，在我运行应用程序后，模拟器显示应用程序意外关闭，有时没有关于日历事件的响应，一切正常。请建议我感谢您的帮助。

Button btnLogin;
Button btnRegister;
Button btnsignUp;
ViewFlipper viewFlipper;
EditText etUserName;
EditText etPassword;

EditText etUserNameSignUp;
EditText etPasswordSignUp;
EditText etPhoneSignUp;

Button btnExit;
Button btnHome;
Button btnNotifications;
Button btnAvalability;
Button btnUpdate;

Button btnPublish;
Button btnStatus;
Button btnNotify;

String[] companies = new String[] { "Infosys", "Wipro", "Cisco", "ibm",
        "tcs", "NWS" };

int[] images = new int[] { R.drawable.notifications,
        R.drawable.notifications, R.drawable.notifications,
        R.drawable.notifications, R.drawable.notifications,
        R.drawable.notifications,

};

String[] dates = new String[] { "21/08/12", "22/08/12", "20/08/12",
        "16/08/12", "18/08/12", "24/08/12", };

String[] type = new String[] { "Face To Face", "Written", "Online",
        "telephonc", "group discussion", "telephonic" };

日历是 Google Apps 的一部分，因此在模拟器中不可用。

第一种方法：在安装了 Google Calendar 应用程序的 android 设备上测试您的应用程序。

第二种方法：在您的模拟器中安装 Google 日历应用程序并在其中测试您的应用程序。

这个答案会给你更多帮助。

编辑 ：

您可以检查是否安装了具有特定包名称的应用程序

public boolean check()
{
    try{
        ApplicationInfo info = getPackageManager().getApplicationInfo("packagename", 0 );
        return true;
    } catch( PackageManager.NameNotFoundException e ){
        return false;
    }
}
