SearchView 激活时如何获取 onBackPressed() ？

我该如何处理onBackPressed()在搜索模式？我已经在以下位置实施了搜索ActionBar，我想处理onBackPressed().

Edit:

At MainActivity我已经添加了这个，但只有在搜索关闭时才会收到通知

@Override
public void onBackPressed() {
    mMenu.findItem(R.id.menu_eye).setVisible(true);
    mMenu.findItem(R.id.menu_layers).setVisible(true);
    super.onBackPressed();  
};

我的搜索操作侦听器如下所示：

import com.cyrilmottier.polaris.PolarisMapView;

import android.app.SearchManager.OnCancelListener;
import android.content.Context;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.SearchView;

public class SearchListener implements SearchView.OnQueryTextListener, SearchView.OnCloseListener, SearchView.OnSuggestionListener, OnClickListener, OnCancelListener{

    private Context mContext;
    private PolarisMapView mMapView;
    private Menu mMenu;
    private SearchView mSearchView;

    public SearchListener(Context c, PolarisMapView mMapView, Menu mMenu, SearchView mSearchView){
        this.setmContext(c);
        this.setmMapView(mMapView);
        this.setmMenu(mMenu);
        this.mSearchView = mSearchView;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        return false;
    }

    @Override
    public boolean onQueryTextSubmit(String query) {
        if (Constants.searchPlaceNavigate(query, mContext, mMapView))
            return this.onClose();
        return false;
    }

    public Context getmContext() {
        return mContext;
    }

    public void setmContext(Context mContext) {
        this.mContext = mContext;
    }

    public PolarisMapView getmMapView() {
        return mMapView;
    }

    public void setmMapView(PolarisMapView mMapView) {
        this.mMapView = mMapView;
    }

    @Override
    public boolean onSuggestionClick(int position) {
        String p = mSearchView.getSuggestionsAdapter().getCursor().getString(position);
        if(position== 0)
            p = mSearchView.getSuggestionsAdapter().getCursor().getString(position*4+1);
        if(p != null)
            if(position== 0)
                Constants.searchPlaceNavigate(mSearchView.getSuggestionsAdapter().getCursor().getString(position*4+1), mContext, mMapView);
            else
                Constants.searchPlaceNavigate(mSearchView.getSuggestionsAdapter().getCursor().getString(position), mContext, mMapView);
        return this.onClose();
    }

    @Override
    public boolean onSuggestionSelect(int position) {

        return false;
    }

    @Override
    public boolean onClose() {
        mMenu.findItem(R.id.menu_eye).setVisible(true);
        mMenu.findItem(R.id.menu_layers).setVisible(true);
        mMenu.findItem(R.id.menu_search).collapseActionView();
        return true;
    }

    public Menu getmMenu() {
        return mMenu;
    }

    public void setmMenu(Menu mMenu) {
        this.mMenu = mMenu;
    }

    public SearchView getmSearchView() {
        return mSearchView;
    }

    public void setmSearchView(SearchView mSearchView) {
        this.mSearchView = mSearchView;
    }

    @Override
    public void onClick(View v) {
        this.onClose();
    }

    @Override
    public void onCancel() {
        this.onClose();

    }

}

另一种方法是监听 MenuItem 的 ActionExpand/Collapse ：

    MenuItem searchMenuItem = menu.findItem(R.id.menu_search);
    searchMenuItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {

        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {
            // Do whatever you need
            return true; // KEEP IT TO TRUE OR IT DOESN'T OPEN !!
        }

        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {
            // Do whatever you need
            return true; // OR FALSE IF YOU DIDN'T WANT IT TO CLOSE!
        }
    });
    SearchView searchView = (SearchView) searchMenuItem.getActionView();
    ... // Keep doing as you do

我认为这种方式更干净，因为你可以直接收听你想要的内容
