本文介绍了ActionBarSherlock - 搜索查看为空？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在SherlockListActivity加入搜索功能，操作栏但是，当我尝试实例化搜索查看它总是空：
I am adding Search functionality to Action Bar in a SherlockListActivity however, when I try to instantiate SearchView its always null:
@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);
}
activity_main_menu.xml：
activity_main_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/activity_main_menu_search"
android:title="@string/search"
android:icon="@android:drawable/ic_menu_search"
android:showAsAction="ifRoom|collapseActionView"
android:actionViewClass="com.actionbarsherlock.widget.SearchView " />
<item android:id="@+id/activity_main_menu_purchase"
android:title="@string/purchase"
android:icon="@drawable/ic_launcher_market_holo"
android:showAsAction="ifRoom|collapseActionView" />
</menu>
此外，我不得不说，我已经正确导入所需的类：
Also I have to say that I have correctly imported required classes:
import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.app.ActionBar.OnNavigationListener;
import com.actionbarsherlock.app.SherlockListActivity;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuItem;
import com.actionbarsherlock.view.MenuItem.OnActionExpandListener;
import com.actionbarsherlock.widget.SearchView;
这是堆栈跟踪。当搜索查看被实例化，数收益这样的：
And this is stack trace. When SearchView is instantiated, log returns this:

然后，搜索查看为空，因此调用SearchView.setOnQueryTextListener（）时，我得到一个NullPointerException异常;
Then, SearchView is null, so I get a NullPointerException when calling SearchView.setOnQueryTextListener();

推荐答案
好了，本身是由ActionBarSherlock库导致了错误，你可以在GitHub上这里的问题：https://github.com/JakeWharton/ActionBarSherlock/issues/685
Well, the error itself is caused by ActionBarSherlock library, you can find the issue in GitHub here: https://github.com/JakeWharton/ActionBarSherlock/issues/685
和张贴在这里评论是我的解决方案：
https://github.com/JakeWharton/ActionBarSherlock/issues/685#issuecomment-11670533
And the comment posted here was my solution: https://github.com/JakeWharton/ActionBarSherlock/issues/685#issuecomment-11670533
转到RES /值-V14 / ABS库项目的abs_themes.xml：那么你应该先修改两个主题是这样的：
Go to res/values-v14/abs_themes.xml of ABS library project: then you should edit first two themes like this:
<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>
另外不要忘记在你的清单声明对于那些使用它的活动：
Also dont forget to declare in your manifest for those activities which use it:
android:theme="@style/Theme.Sherlock.Light"
