android studio 2.3上的输入和输出

Question

This is kind of beginner/noob question, but I want to use InputActivity.java and activity_input.xml as the one that the user use to input data. The code for the input are as shown below:

InputActivity.java

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

}

activity_input.xml

<?xml version="1.0" encoding="utf-8"?>

</android.support.constraint.ConstraintLayout>

The code for the output part of my application are shown below:

HasilActivity.java

package com.lukmanyahoo.denny.myapplication;

import android.os.Bundle;

public class HasilActivity extends AppCompatActivity {

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_hasil);
    }
}

Thanks for taking time answering this. I am new in giving question here.

Answer 1

In your InputActivity

public class InputActivity extends 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)

}

and in your HasilActivity

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");
}
}

that is :)
