Android ActionBarSherlock-SearchView是否为空？,android,actionbarsherlock,classnotfoundexception,searchview,Android,Actionbarsherlock,Classnotfoundexception,Searchview,我将搜索功能添加到SherlockListActivity中的操作栏，但是，当我尝试实例化SearchView时，其始终为空： @Override public boolean onCreateOptionsMenu(Menu menu) { getSupportMenuInflater().inflate(R.menu.activity_main_menu, menu); SearchView searchView = (SearchView) menu.findItem(R.

我将搜索功能添加到SherlockListActivity中的操作栏，但是，当我尝试实例化SearchView时，其始终为空：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getSupportMenuInflater().inflate(R.menu.activity_main_menu, menu);
    SearchView searchView = (SearchView) menu.findItem(R.id.activity_main_menu_search).getActionView();
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener(){
            public boolean onQueryTextSubmit(String p1){
                List<Application> auxList = Search.search(mContext, p1);
                AdapterApp aux = new AdapterApp(mContext, auxList);
                setListAdapter(aux);
                getListView().setOnItemClickListener(aux.getItemClickListener());
                return true;
            }

            public boolean onQueryTextChange(String p1){
                return false;
            }           
    });
    return super.onCreateOptionsMenu(menu);
}

这是堆栈跟踪。在实例化SearchView时，日志将返回以下内容：

然后，SearchView为null，因此调用SearchView.setOnQueryTextListener（）时，我得到一个NullPointerException

我浪费了一天的时间寻找错误的原因，但没有成功。。。请告诉我需要帮助

我不太熟悉ActionBarSherlock SearchView类的用法，但我可以告诉你的是，如果你查看，他不会试图从菜单中获取SearchView，而是创建SearchView并将其设置到菜单中

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    //Used to put dark icons on light action bar
    boolean isLight = SampleList.THEME == R.style.Theme_Sherlock_Light;

    //Create the search view
    SearchView searchView = new SearchView(getSupportActionBar().getThemedContext());
    searchView.setQueryHint("Search for countries…");
    searchView.setOnQueryTextListener(this);
    searchView.setOnSuggestionListener(this);

    if (mSuggestionsAdapter == null) {
        MatrixCursor cursor = new MatrixCursor(COLUMNS);
        cursor.addRow(new String[]{"1", "'Murica"});
        cursor.addRow(new String[]{"2", "Canada"});
        cursor.addRow(new String[]{"3", "Denmark"});
        mSuggestionsAdapter = new SuggestionsAdapter(getSupportActionBar().getThemedContext(), cursor);
    }

    searchView.setSuggestionsAdapter(mSuggestionsAdapter);

    menu.add("Search")
        .setIcon(isLight ? R.drawable.ic_search_inverse : R.drawable.abs__ic_search)
        .setActionView(searchView)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);

    return true;
}

错误本身是由ActionBarSherlock库引起的，您可以在GitHub中找到问题：

这里的评论是我的解决方案：

转到abs库项目的res/values-v14/abs_themes.xml：然后您应该像这样编辑前两个主题：

<style name="Sherlock.__Theme" parent="android:Theme.Holo">
    <item name="textColorPrimary">@color/abs__primary_text_holo_light</item>
    <item name="textColorPrimaryInverse">@color/abs__primary_text_holo_dark</item>
</style>
<style name="Sherlock.__Theme.Light" parent="android:Theme.Holo.Light">
    <item name="textColorPrimary">@color/abs__primary_text_holo_light</item>
    <item name="textColorPrimaryInverse">@color/abs__primary_text_holo_dark</item>
</style>

关于上述github问题，我已经解决了。（奇怪的修正，因为您刚刚删除了主题的基础。）

在哪个Android版本上运行，以及您将哪个主题设置为默认主题？我将target sdk设置为17，min sdk设置为8。但是我发现了错误：。在这里发表的评论是我的解决方案：所有这些似乎都是不必要的。。。我发现了错误：。此处发布的评论是我的解决方案：。谢谢你的回答，投赞成票：）
