我有一个问题，一些设备无法选择一个listview项目，我似乎无法弄清楚代码中出了什么问题 - 选择一个listview项目在我的设备和仿真器上正常工作。我已检查了重点，但这似乎不是问题。有人有主意吗？Android ListView问题
公共类GroupListFragment扩展ListFragment
@Override
public void onListItemClick(ListView listView, View view, int position, long id) {
super.onListItemClick(listView, view, position, id);
Group group = (Group) listView.getItemAtPosition(position);
mCallbacks.onItemSelected(group);
}
公共类GroupListActivity扩展FragmentActivity实现GroupListFragment.Callbacks
@Override
public void onItemSelected(Group group) {
if (twoPaneLayout) {
// seems to work fine
Bundle arguments = new Bundle();
arguments.putLong(GroupDetailFragment.GROUP_ITEM_ID, group.getId());
GroupDetailFragment fragment = new GroupDetailFragment();
fragment.setArguments(arguments);
replaceDetailPane(fragment);
} else {
// does not work on some mobile devices
Intent detailIntent = new Intent(this, GroupDetailActivity.class);
detailIntent.putExtra(GroupDetailFragment.GROUP_ITEM_ID, group.getId());
startActivity(detailIntent);
overridePendingTransition(R.anim.slide_in_left, R.anim.slide_out_left);
}
}

我们可以看到你的'OnItemClickListener'吗？另外，当你说它不起作用时，这是什么意思？只是'OnItemClickListener'不能触发？不应该发生什么？ – Blumer 2013-03-05 19:50:52
我已更新主要评论。问题是当用户点击移动设备上的列表项时，它不会触发'onListItemClick'方法，并且不会加载详细信息活动。但是，我不确定为什么'onListItemClick'永远不会被调用。 – Abid 2013-03-05 23:28:16
