单击Android中的搜索图标时如何从工具栏隐藏菜单项

Question

我的工具栏包含搜索图标和刷新图标，当我单击搜索图标然后搜索视图从onCreateOptionMenu（）膨胀时，但刷新图标没有隐藏。如果我在onMenuItemActionExpand（）中隐藏刷新图标，则在向后按搜索视图后退图标菜单项搜索和刷新均隐藏，默认设置图标可见。以下是我已实现的代码。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);
    }
}
