andorid后台根据用户权限配置前台菜单功能实现

Posted 2022-12-08 静思浅行

项目需求，android显示的菜单要通过后台用户权限控制显示哪些菜单，前端通过接口请求菜单获取菜单Id集合然后显示相应的菜单。（获取菜单后可以在本地缓存下来，在没网的情况下依然可以显示。）

首先看看效果图

第一步：因为每个菜单的Id是固定不变的，在前端可以定义一个菜单实体类，如下：

//中队-受理业务分配
MenuBean menuBean2 = new MenuBean();
menuBean2.setMenuId(87);//菜单Id
menuBean2.setTabId(2);//该菜单所属页面
menuBean2.setTitle(BaseApplication.context.getString(R.string.tal1_act1));//菜单标题
menuBean2.setDrawbleId(R.drawable.icon_divider);//菜单图片
menuBean2.setIntent(new Intent(BaseApplication.context, TaskToMemberActivity.class));//点击菜单跳转到的页面
menus.add(menuBean2);
//中队 --任务处置审批（中队反馈确认）
MenuBean menuBean9 = new MenuBean();
menuBean9.setMenuId(86);
menuBean9.setTabId(2);
menuBean9.setTitle(BaseApplication.context.getString(R.string.tal2_act6));
menuBean9.setDrawbleId(R.drawable.icon_rwcz_confirm);
Intent submitIntent = new Intent(BaseApplication.context, TaskHandlerActivity.class);
submitIntent.putExtra("url", URLTool.QueryWorkTaskManageZDCZList);
submitIntent.putExtra("title", BaseApplication.context.getString(R.string.tal2_act6));
menuBean9.setIntent(submitIntent);
menus.add(menuBean9);

//中队 --巡检问题确认
MenuBean menuBean126 = new MenuBean();
menuBean126.setMenuId(126);
menuBean126.setTabId(2);
menuBean126.setTitle(BaseApplication.context.getString(R.string.tal2_act7));
menuBean126.setDrawbleId(R.drawable.icon_zdsp);
menuBean126.setIntent(new Intent(BaseApplication.context, ZDConfirmActivity.class));
menus.add(menuBean126);

第二步：登录完成之后请求角色菜单集合，然后根据角色菜单Id集合显示菜单
/**
 * 获取每个tab下的菜单
 *
 * @param tabID 页面ID
 * @param roleMenuResult 后台返回的角色菜单ID集合
 * @return
 */
public static List<MenuBean> getMenu(RoleMenuResult roleMenuResult,int tabID) 
    List<MenuBean> menuResult = new ArrayList<>();
    menuResult.clear();
    if(roleMenuResult==null)
        return menuResult;
    
    List<RoleMenu> menuList = roleMenuResult.getDt();
    if(menuList==null)
        return null;
    

    for (int i = 0; i < menus.size(); i++) 
        MenuBean localMenu = menus.get(i);
        if(localMenu.getTabId()!=tabID)
            continue;
        
        for (int j = 0; j < menuList.size(); j++) 
            RoleMenu roleMenu = menuList.get(j);
           if(localMenu.getMenuId()==roleMenu.getMENUID())
               if(!menuResult.contains(localMenu))
                   menuResult.add(menus.get(i));
               
           
        
    
    return menuResult;

第三步：使用gradView显示菜单：
menus = MenuUtils.getMenu(MainActivity.roleMenuResult, 3);
本地默认的菜单可以在本地定义好，然后添加到集合中。
menus.addAll(defaultMenus);
adapter = new RoleMenuAdaper(menus);
gridView.setAdapter(adapter);
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() 
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) 
        Intent intent = (Intent) menus.get(position).getIntent();
        if (intent == null) 
            //现场取证
            if (menus.get(position).getTitle().equals(mActivity.getString(R.string.quzheng))) 
                popupWindow.showAtLocation(ll_main, Gravity.BOTTOM, 0, 0);
                CommonUtils.makeWindowDark(mActivity);
             else 
                ToastUtils.showShort(mActivity, "该功能暂未开放");
            
            return;
        
这些操作可以放到菜单工具类中，方便操作,可参考下面的代码片段
