android studio 2.3의 입력과 출력

이것은 초보자/멍청한 질문입니다.하지만 사용자가 데이터를 입력하는 데 InputActivity.java와 activity_input.xml을 사용하고 싶습니다.android studio 2.3의 입력과 출력

InputActivity.java

을

package com.lukmanyahoo.denny.myapplication; 

import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 

public class InputActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_input); 
    } 

    //Send data to HasilActivity.java 

}

감사합니다. 나는 여기서 새로운 질문을한다. 당신의 InputActivity에서

는

공용 클래스 InputActivity는 AppCompatActivity {

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_input); 
} 

//Send data to HasilActivity.java 
Intent intent = new Intent(this, HasilActivity.class); 
// put your data here 
intent.putExtra("value_one", editText.getText().toString().trim()); 
intent.putExtra("value_two", editText2.getText().toString().trim()); 
startActivity(intent) 

}

를 확장하고 HasilActivity에

public class HasilActivity extends AppCompatActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_hasil); 

    String value = getIntent().getStringExtra("value_one"); 
    String value2 = getIntent().getStringExtra("value_two"); 
} 
}

입니다
