我有一个带有搜索图标的操作栏。单击搜索图标时，它会展开为搜索栏，用户可以在其中键入搜索内容。

问题是当用户输入搜索时，我希望搜索栏折叠回一个图标，但我无法让它在我的一生中发生。

我的操作栏菜单如下所示:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity" >

    <item android:id="@+id/menu_search2"
        android:actionViewClass="android.widget.SearchView"
        android:title="Search"
        android:icon="@android:drawable/ic_menu_search"
        android:showAsAction="always|collapseActionView|"
        android:onClick="goToSearch"
        />

    <item android:id="@+id/action_scan"
        android:icon="@drawable/barcode"
        android:onClick="scanBarcode"
        android:showAsAction="ifRoom|collapseActionView"
        />

</menu>

我的搜索 Activity 如下所示:

public class Search extends Fragment implements SearchView.OnQueryTextListener, ReadJSONResult.OnArticleSelectedListener {

    private ListView lv;
    View v;
    SearchView searchView;
    private SearchView mSearchView;
    private MenuItem mSearchMenuItem;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        //set layout here
        v = inflater.inflate(R.layout.activity_search, container, false);
        setHasOptionsMenu(true);
        getActivity().setTitle("Search");


        //get user information
        SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getActivity());
        String userName = prefs.getString("userName", null);
        String userID = prefs.getString("userID", null);


        return v;


}

    @Override
    public void onCreateOptionsMenu (Menu menu, MenuInflater inflater) {
        // Inflate the menu; this adds items to the action bar if it is present.

        searchView = (SearchView) menu.findItem(R.id.menu_search2).getActionView();
        searchView.setOnQueryTextListener(this);
        searchView.setIconified(false);
    }


    public boolean onQueryTextSubmit (String query) {

        //toast query
        //make json variables to fill
        searchView.setIconified(true);
        searchView.clearFocus();

        // url to make request
        String url = "myURL";



        try {
            query = URLEncoder.encode(query, "UTF-8");
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


        String jsonUrl = url + query;


        //todo: get json
        ReadJSONResult task = new ReadJSONResult(getActivity());
        task.setOnArticleSelectedListener(this);
        task.execute(jsonUrl);

        return false;
    }





    @Override
    public boolean onQueryTextChange(String newText) {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public void onArticleSelected(String b, String brewery){
        searchView.setIconified(true);
        searchView.clearFocus();
        searchView.postInvalidate();
        //code to execute on click
        Fragment Fragment_one;
        FragmentManager man= getFragmentManager();
        FragmentTransaction tran = man.beginTransaction();

        //adds beer data to shared prefs for beer tabs
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getActivity());
        SharedPreferences.Editor editor = preferences.edit();
        editor.putString("beerID",b);
        editor.putString("breweryID",brewery);
        editor.commit();
        Fragment_one = new BeerTabs();

        tran.replace(R.id.main, Fragment_one);//tran.
        tran.addToBackStack(null);
        tran.commit();

    }



}

最佳答案

以下代码是一种更简单的方法，即使 SearchView 小部件不在操作栏上也可以使用:

searchView.setQuery("", false);
searchView.setIconified(true);

这会使 SearchView 在搜索后崩溃。

关于android - 搜索后操作栏搜索不会关闭，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23072123/
