第一次冲刺（二）

今天我完成了忘记密码的activity的设计。

代码为:

package com.example.hotel.Activity;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

import com.example.hotel.Database.MysqlUser;
import com.example.hotel.R;

import java.sql.SQLException;

public class NopwdActivity extends AppCompatActivity {
    private Button Button;
    private EditText Userid,Userphone;
    private TextView Pwd;
    private String searpwd,searphone;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_nopwd);
        Userid=(EditText) findViewById(R.id.userid);
        Userphone=(EditText)findViewById(R.id.userphone);
        Pwd=(TextView) findViewById(R.id.pwdresult);
        Button=findViewById(R.id.searchpwd);
        Button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Thread thread=new Thread(new Runnable() {
                    @Override
                    public void run() {
                        MysqlUser mysqlUser=new MysqlUser();
                        try {
                            String sql="select password from userinfo where id='"+Userid.getText().toString()+"'";
                            searpwd=mysqlUser.select(sql).toString();
                            String sql2="select phone from userinfo where id='"+Userid.getText().toString()+"'";
                            searphone=mysqlUser.select(sql2).toString();
                        } catch (SQLException e) {
                            e.printStackTrace();
                        }
                    }
                });
                thread.start();
                try {
                    thread.join();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                search();
            }
        });
    }
    public void search(){
        String userid=Userid.getText().toString();
        String userphone=Userphone.getText().toString();
        if(userphone.equals(searphone)){
            Pwd.setText("您的密码为："+searpwd);
        }
    }

}
