昨天成就
android端的主界面设计
今天任务：
导航抽屉菜单
模块化功能展示
职级体系表格
响应式交互设计
具体代码如下：

    // 初始化抽屉导航
    drawerLayout = findViewById(R.id.drawer_layout);
    NavigationView navigationView = findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    // 初始化模块列表
    RecyclerView recyclerView = findViewById(R.id.module_recycler_view);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
    moduleAdapter = new ModuleAdapter(loadModules());
    recyclerView.setAdapter(moduleAdapter);
}

private List<Module> loadModules() {
    List<Module> modules = new ArrayList<>();
    modules.add(new Module("组织架构管理", "企业管理+组织架构+部门+编制", "树形组织编辑、编制预警", true));
    modules.add(new Module("职位职级体系", "职位管理+职级管理", "职级薪资关联设置", false));

    modules.add(new Module("合同全生命周期", "合同管理+台账", "到期自动提醒", false));
    return modules;
}

@Override

    switch (item.getItemId()) {
        case R.id.nav_org:
            startActivity(new Intent(this, OrganizationActivity.class));

    }
    drawerLayout.closeDrawer(GravityCompat.START);
    return true;
}

}

今天遇到的困难：在编写适配器时报错无法解析R符号，原因是XML 文件有错误，在检查了布局文件后发现了问题在于Can't download Android Plugin component: layoutlib-resources
是由于 Android Studio 的插件组件下载失败或损坏导致的，在重载了插件后问题得到解决
