Question

我有一个通用的SherlockListFragment，在我的应用程序中用于不同的情况。这个片段有一个选项菜单项（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);

}

问题是其中一个片段实例在ViewPager中使用，当刷到它时，应用程序崩溃（仅在HTC Desire上安装android 2.3.3），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。

以下是崩溃的堆栈跟踪：

我真的坚持这个问题......任何帮助都会很棒。

修改

切换到ActionBarSherlock dev分支 - 没有崩溃...谢谢大家。

Answer 2

尝试：

private editTextSearch;

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getSupportMenuInflater().inflate(R.menu.your_menu, menu);       
    menu.getItem(0).setActionView(R.layout.search); //Number of menu item
    editTextSearch = (EditText) menu.getItem(0).getActionView().findViewById(R.id.edit_search); //Your editetxt search

    return super.onCreateOptionsMenu(menu);
}

Sherlock List Fragment'onCreate OptionMenu'在android 2.3.3上崩溃
