How to call notifyDataSetChanged() from a generic Adapter

由 房东的猫 提交于 2019-12-07 09:35:22
问题 An OnItemClickListener for a ListView has the following method: @Override public void onItemClick(AdapterView<?> parent, View v, int position, long id) I'd like to have the adapter behind the ListView refresh, and I believe this is done through the use of: BaseAdapter.notifyDataSetChanged() How do I use the parent parameter in the onItemClick method to do this? So far I've tried: parent.getAdapter().notifyDataSetChanged(); This throws an error because the object returned is of class

vmware虚拟机三种网卡

由 萝らか妹 提交于 2019-12-07 03:47:35
vmware为我们提供了三种网络工作模式，它们分别是： Bridged（桥接模式） 、 NAT（网络地址转换模式） 、 Host-Only（仅主机模式） 。 打开vmware虚拟机，我们可以在选项栏的“编辑”下的“虚拟网络编辑器”中看到VMnet0（桥接模式）、VMnet1（仅主机模式）、VMnet8（NAT模式），那么这些都是有什么作用呢？其实，我们现在看到的VMnet0表示的是用于桥接模式下的虚拟交换机；VMnet1表示的是用于仅主机模式下的虚拟交换机；VMnet8表示的是用于NAT模式下的虚拟交换机。 同时，在主机上对应的有VMware Network Adapter VMnet1和VMware Network Adapter VMnet8两块虚拟网卡，它们分别作用于仅主机模式与NAT模式下。在“网络连接”中我们可以看到这两块虚拟网卡，如果将这两块卸载了，可以在vmware的“编辑”下的“虚拟网络编辑器”中点击“还原默认设置”，可重新将虚拟网卡还原。 小伙伴看到这里，肯定有疑问，为什么在真机上没有VMware Network Adapter VMnet0虚拟网卡呢？那么接下来，我们就一起来看一下这是为什么。 一、Bridged（桥接模式） 什么是桥接模式？桥接模式就是将主机网卡与虚拟机虚拟的网卡利用虚拟网桥进行通信。在桥接的作用下，类似于把物理主机虚拟为一个交换机

《每日一剂》适配器刷新报错adapter.notifyDataSetChanged()解决

由 二次信任 提交于 2019-12-06 23:55:33
在使用ListView过程中，有时会出现The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes. 原因是给ListView设置的adapter，修改数据源时放在了非UI线程中去执行，在主线程中调用adapter的notifyDataSetChanged()方法，有时会抛出此异常，（亦即，当ListView缓存的数据Count和ListView中Adapter.getCount()不等时，会抛出该异常。）因此，修改adapter数据源时需要放在主线程中去执行，这里给出两种思路。 提前将adapter的数据全清空了adapter.getDateList.clear()，且并没有及时调用adapter.notifyDataSetChanged()，导致ListView没有数据而抛java.lang
