package com.example.login;

import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;

import androidx.appcompat.app.AppCompatActivity;

public class LoginResultActivity extends AppCompatActivity {

TextView TextView_get;
 @Override
 protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
TextView_get = findViewById(R.id.TextView_get);


Intent intent =getIntent();
Bundle bundle = intent.getExtras();
 String id = bundle.getString("id");
 String password = bundle.getString("password");
TextView_get.setText(id + "/" + password);
}

}

여기서 TextView_get = findViewById(R.id.TextView_get); 

R.id.뒤에 TextView_get이 계속 빨간 줄인데 어떡하죠
