Android开发之弹出菜单

PopupMenu

首先需要写一个menu文件，每一个item代表菜单里的一项。

然后实例化PopupMenu对象，通过该对象调用getMenuInfllater获得MenuInflater对象

再绑定menu文件

最后写点击事件

    @OnClick(R.id.main_post_order)
    public void orderOnClick(View v){
        showOrderWayMenu(v);
    }

    private void showOrderWayMenu(View v){
        final PopupMenu popupMenu=new PopupMenu(getActivity(),v);
        popupMenu.getMenuInflater().inflate(R.menu.menu_order_post,popupMenu.getMenu());
        popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                if(item.getTitle().equals("按时间")){
                    Log.d("OrderPost","按时间");
                    return true;
                }else if(item.getTitle().equals("按热度")){
                    return true;
                }
                return false;
            }
        });
        popupMenu.show();
    }
