体温填报app开发

设计思路：

       制作体温填报网页，利用按钮跳转。

 代码如下：

 

package com.example.myapp1;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import com.example.myapp1.service.UserService;

public class P extends AppCompatActivity
{
    EditText username,password;
    Button register;
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_p);
        findViews();
        register.setOnClickListener(new View.OnClickListener(){
            public void onClick(View v)
            {
                String name=username.getText().toString().trim();
                String pass=password.getText().toString().trim();
                Log.i("TAG",name+"_"+pass);
                UserService uService=new UserService(P.this);
                User user=new User();
                user.setUsername(name);
                user.setPassword(pass);
                uService.register(user);
                Toast.makeText(P.this, "注册成功", Toast.LENGTH_LONG).show();
            }
        });
    }
    private void findViews()
    {
        username=(EditText) findViewById(R.id.name);
        password=(EditText) findViewById(R.id.password);
        register=(Button) findViewById(R.id.but);
    }
}

        B=findViewById(R.id.b);
        B.setOnClickListener(new View.OnClickListener() {
            @Override

                else
