今天开始写注册的后端代码：

package com.example.team;

import android.content.Intent;
import android.graphics.Typeface;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;

import com.example.R;
import com.example.team.dao.UserDao;
import com.example.team.entity.User;

public class RegisterActivity extends AppCompatActivity {
    private TextView m_text,text,textview;
    EditText name = null;
    EditText username = null;
    EditText password = null;
    EditText phone = null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_register);
        m_text = findViewById(R.id.Text1);
        text = findViewById(R.id.Text2);
        textview = findViewById(R.id.textView1);
        name = findViewById(R.id.name);
        username = findViewById(R.id.username);
        password = findViewById(R.id.password);
        phone = findViewById(R.id.phone);
        Typeface typeface = Typeface.createFromAsset(getAssets(),"font/xiniu.ttf");
        Typeface typeface2 = Typeface.createFromAsset(getAssets(), "font/momo.ttf");
        textview.setTypeface(typeface);
        m_text.setTypeface(typeface2);
        text.setTypeface(typeface2);
        name.setTypeface(typeface);
        username.setTypeface(typeface);
        phone.setTypeface(typeface);
        password.setTypeface(typeface);

    }


    public void register(View view){
        String cname = name.getText().toString();
        String cusername = username.getText().toString();
        String cpassword = password.getText().toString();
        System.out.println(phone.getText().toString());
        String cphone = phone.getText().toString();
        User user = new User();

        user.setName(cname);
        user.setUsername(cusername);
        user.setPassword(cpassword);
        user.setPhone(cphone);

        new Thread(){
            @Override
            public void run() {

                int msg = 0;

                UserDao userDao = new UserDao(RegisterActivity.this);

                User uu = userDao.findUser(user.getName());

                if(uu != null){
                    msg = 1;
                }

                boolean flag = userDao.register(user);
                if(flag){
                    msg = 2;
                }
                hand.sendEmptyMessage(msg);

            }
        }.start();


    }
    final Handler hand = new Handler()
    {
        @Override
        public void handleMessage(Message msg) {
            if(msg.what == 0)
            {
                Toast.makeText(getApplicationContext(),"注册失败",Toast.LENGTH_LONG).show();

            }
            if(msg.what == 1)
            {
                Toast.makeText(getApplicationContext(),"该账号已经存在，请换一个账号",Toast.LENGTH_LONG).show();

            }
            if (msg.what == 2) {
                Toast.makeText(getApplicationContext(),"注册成功",Toast.LENGTH_LONG).show();
                Intent intent = new Intent(RegisterActivity.this, MainActivity.class);
                startActivity(intent);
                finish();
            }
        }
    };
}
