将操作设置为菜单图标Android工具栏

Question

我的应用程序中有一个工具栏，其中 searchView widget部件有两个用于搜索图标的图标，而另一个图标只是一个简单的图标。每当我单击搜索按钮时，我的工具栏都会更改为搜索视图，但是每当我触摸网格按钮时，我的工具栏再次我的工具栏 searchView 都会可见，但是我不想打开 searchView 在网格按钮上单击。我只希望它可以在我的搜索按钮中看到它。

代码：

public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.vid_search_menu_items, menu);
        //Add Tint to icon
        Drawable drawable = menu.findItem(R.id.action_grid).getIcon();
        drawable = DrawableCompat.wrap(drawable);
        DrawableCompat.setTint(drawable, ContextCompat.getColor(this,R.color.white));
        menu.findItem(R.id.action_grid).setIcon(drawable);

        MenuItem menuItem = menu.findItem(R.id.action_search);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(menuItem);
        searchView.setOnQueryTextListener(this);
        MenuItemCompat.setOnActionExpandListener(menuItem, new MenuItemCompat.OnActionExpandListener() {
            @Override
            public boolean onMenuItemActionCollapse(MenuItem item) {
                // Do something when collapsed
                //  Toast.makeText(getActivity(),"collapsed",Toast.LENGTH_LONG).show();
                searchMeta.setVisibility(View.GONE);
                return true;  // Return true to collapse action view
            }
            @Override
            public boolean onMenuItemActionExpand(MenuItem item) {
                // Do something when expanded
                // Toast.makeText(getActivity(),"expanded",Toast.LENGTH_LONG).show();
                searchMeta.setVisibility(View.VISIBLE);
                return true;  // Return true to expand action view
            }
        });
       return  super.onCreateOptionsMenu(menu);
    }
 @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        switch (id) {
            case R.id.action_search:
               Toast.makeText(this,"search",Toast.LENGTH_LONG).show();
                break;
            case R.id.action_grid:
                Toast.makeText(this,"search",Toast.LENGTH_LONG).show();
                isList = !isList;
                if(isList){
                    //Change Item Icon
                    Drawable myDrawable = ContextCompat.getDrawable(this, R.drawable.ic_list_2);
                    myDrawable = DrawableCompat.wrap(myDrawable);
                    DrawableCompat.setTint(myDrawable, ContextCompat.getColor(this,R.color.white));
                    item.setIcon(myDrawable);
                }else{
                    Drawable myDrawable = ContextCompat.getDrawable(this, R.drawable.ic_grid_2);
                    myDrawable = DrawableCompat.wrap(myDrawable);
                    DrawableCompat.setTint(myDrawable, ContextCompat.getColor(this,R.color.white));
                    item.setIcon(myDrawable);
                }
                break;
        }

从第二项中删除 app:actionViewClass="android.support.v7.widget.SearchView"，然后查看魔术：）
