2.登录页 LoginActivity 是一个用户登录界面允许用户输入账号和密码进行登录验证。如果账号不存在则显示相应提示如果密码错误则提示重新输入如果验证通过则跳转到主界面 MainActivity。用户也可以点击注册按钮 tvRegister 跳转到注册界面 RegisterActivity 进行新账号注册。

}
7.我的页面 这段代码实现了一个包含抽屉菜单的个人信息界面PersonFragment具体功能如下
1. 在 onCreateView() 方法中加载布局并初始化视图控件如订单、个人信息、分享按钮和圆形头像设置点击事件监听器。 2. NavigationView 设置了菜单项的选中监听器用于关闭抽屉菜单。 3. onClick() 方法根据点击事件执行不同的操作 - 点击个人信息按钮 (person)显示提示信息并打开左侧抽屉菜单。 - 点击历史订单按钮 (order)显示提示信息并跳转到订单活动 (OrderActivity)。 - 点击分享按钮 (share)调用 shareSoftware() 方法分享软件信息。
总体来说这段代码实现了个人信息页面的基本功能包括按钮点击事件处理和抽屉菜单的使用。

import android.view.LayoutInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;

import android.widget.Toast;import androidx.core.view.GravityCompat;
import androidx.drawerlayout.widget.DrawerLayout;
import androidx.fragment.app.Fragment;import com.google.android.material.navigation.NavigationView;import de.hdodenhof.circleimageview.CircleImageView;
import com.example.ordersystem.Activity.OrderActivity;
import com.example.ordersystem.R;public class PersonFragment extends Fragment implements View.OnClickListener{private TextView order, person, share;private CircleImageView circleImage;private DrawerLayout drawerLayout;Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view inflater.inflate(R.layout.fragment_person, container, false);// 获取控件实例order view.findViewById(R.id.order);person view.findViewById(R.id.person);share view.findViewById(R.id.share);circleImage view.findViewById(R.id.circle_image);drawerLayout view.findViewById(R.id.drawer_layout);NavigationView navigationView view.findViewById(R.id.nav_view);navigationView.setCheckedItem(R.id.nav_call);// 设置监听器order.setOnClickListener(this);person.setOnClickListener(this);share.setOnClickListener(this);circleImage.setOnClickListener(this);// 菜单项选中事件的监听器navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {Overridepublic boolean onNavigationItemSelected(MenuItem item) {drawerLayout.closeDrawers();return true;}});return view;}// 分享这个软件到其他用户private void shareSoftware() {Intent intent new Intent(Intent.ACTION_SEND);intent.setType(text/plain);String msg 想随时查找美食吗快来下载订餐系统吧;intent.putExtra(Intent.EXTRA_TEXT,msg);startActivity(Intent.createChooser(intent,分享到....));}Overridepublic void onClick(View view) {switch (view.getId()) {case R.id.person:Toast.makeText(getContext(), 你查看了个人信息, Toast.LENGTH_SHORT).show();drawerLayout.openDrawer(GravityCompat.START);break;case R.id.order:Toast.makeText(getContext(), 你查看了历史订单, Toast.LENGTH_SHORT).show();Intent intent new Intent(getActivity(), OrderActivity.class);startActivity(intent);break;case R.id.share:shareSoftware();break;}}
}8.我的订单页 这段代码实现了一个订单展示页面OrderActivity具体功能如下
1. 在 onCreate() 方法中设置布局并初始化视图包括RecyclerView用于展示订单列表SwipeRefreshLayout用于下拉刷新以及自定义的Toolbar用于显示操作栏。 2. initView() 方法初始化了界面元素设置了RecyclerView的布局管理器和适配器OrderAdapter并添加了下拉刷新的监听器。 3. initOrder() 方法从数据库获取订单数据并初始化到 orderList 中。 4. refreshOrder() 方法通过新线程模拟耗时操作2秒钟然后更新订单数据并通知适配器数据变化同时关闭下拉刷新动画并显示刷新成功的提示。 5. onOptionsItemSelected() 方法监听返回按钮的点击事件点击返回按钮时关闭当前活动。
总体来说这段代码实现了一个简单的订单展示功能包括从数据库加载数据、下拉刷新功能、以及返回按钮的处理。 package com.example.ordersystem.Activity;import androidx.appcompat.app.ActionBar;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;
