我有一个SherlockListFragment
在不同情况下在我的应用程序中使用的泛型。这个片段有一个选项菜单项( a SearchView
),这里是SearchView
创建的代码:
@Override
public void onCreateOptionsMenu(final Menu menu, final MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.all_places, menu);
final MenuItem searchMenuItem = menu.findItem(R.id.action_search);
searchMenuItem.setOnActionExpandListener(this);
final SearchView searchView = (SearchView) searchMenuItem
.getActionView();
searchView.requestFocusFromTouch();
searchView.setQueryHint(getString(R.string.search_query_hint));
searchView.setOnQueryTextListener(this);
}
问题是 ViewPager 中使用了其中一个片段实例,当滑动到它时,应用程序崩溃(仅在 HTC Desire 与 android 2.3.3 上),但适用于 ICS 和 JB 设备。顺便说一句,当手动附加片段(没有ViewPager
)时,不会发生崩溃。
这是崩溃的堆栈跟踪:

我真的被这个问题困住了......任何帮助都会很棒。
编辑
切换到 ActionBarSherlock 开发分支 - 没有崩溃......谢谢大家。
