单击android中的搜索图标时如何隐藏工具栏中的菜单项

Question

我的工具栏包含搜索图标和刷新图标，当我点击搜索图标然后从onCreateOptionMenu（）搜索视图膨胀但刷新图标不会隐藏。如果我在onMenuItemActionExpand（）中隐藏刷新图标，那么在背面按下搜索视图返回图标两个菜单项搜索和刷新获取隐藏和默认设置图标变得可见。下面是我已经实现的代码。请帮助我!!!

MenuItem.java

 @Override
        public boolean onCreateOptionsMenu(final Menu menu) {

            // Inflate the menu; this adds items to the action bar if it is present.
              getMenuInflater().inflate(R.menu.main, menu);
              item_search = menu.findItem(R.id.action_search);
              item_refresh = menu.findItem(R.id.action_refresh);

           final SearchView searchView = (SearchView) MenuItemCompat.getActionView(item_search);
            searchView.setOnSearchClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // hide action item
                    if (menu != null) {
                        menu.findItem(R.id.action_refresh).setVisible(false);
                    }

                }
            });
            searchView.setOnCloseListener(new SearchView.OnCloseListener() {
                @Override
                public boolean onClose() {
                    // re-show the action button
                    if (menu != null) {
                        menu.findItem(R.id.action_refresh).setVisible(true);
                    }
                    return false;

                }
            });

​MenuItem action_search;
MenuItem action_refresh;
 @Override
 public boolean onPrepareOptionsMenu(Menu menu) {
     action_search = menu.findItem(R.id. action_search);
     action_refresh = menu.findItem(R.id. action_refresh);
    return super.onPrepareOptionsMenu(menu);
}
@Override
    public boolean onCreateOptionsMenu(final Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
          getMenuInflater().inflate(R.menu.main, menu);
          item_search = menu.findItem(R.id.action_search);
          item_refresh = menu.findItem(R.id.action_refresh);

       final SearchView searchView = (SearchView) MenuItemCompat.getActionView(item_search);
        searchView.setOnSearchClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // hide action item
                if (action_refresh != null) {
                    action_refresh.setVisible(false);
                  invalidateOptionsMenu();
                }

            }
        });
        searchView.setOnCloseListener(new SearchView.OnCloseListener() {
            @Override
            public boolean onClose() {
                // re-show the action button
                if (action_search != null) {
                    action_search.setVisible(true);
                }
               if (action_refresh != null) {
                   action_refresh.setVisible(true);
                }
                invalidateOptionsMenu();
                return false;

            }
        });

Well you could imitate that yourself by hiding all the other items when the SearchView is expanded:

@Override
public boolean onCreateOptionsMenu(final Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);

    final MenuItem searchItem = menu.findItem(R.id.search);
    SearchView searchView = (android.widget.SearchView) searchItem.getActionView();

    // Detect SearchView icon clicks
    searchView.setOnSearchClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            setItemsVisibility(menu, searchItem, false);
        }
    });
    // Detect SearchView close
    searchView.setOnCloseListener(new SearchView.OnCloseListener() {
        @Override
        public boolean onClose() {
            setItemsVisibility(menu, searchItem, true);
            return false;
        }
    });

    return super.onCreateOptionsMenu(menu);
}

private void setItemsVisibility(Menu menu, MenuItem exception, boolean visible) {
    for (int i=0; i<menu.size(); ++i) {
        MenuItem item = menu.getItem(i);
        if (item != exception) item.setVisible(visible);
    }
}
