import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import com.jeevan.karan.R;
public class FirstActivity extends AppCompatActivity {
EditText editText;
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first);
editText = (EditText)findViewById(R.id.edittext);
button = (Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(),SecondActivity.class);
intent.putExtra(“userName”,editText.getText().toString());
startActivityForResult(intent,100);
}
});
}
}

Java File SecondActivity.java

package com.jeevan.karan.fetch_data;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
import com.jeevan.karan.R;
public class SecondActivity extends AppCompatActivity {
TextView textView;
String username = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
Intent i = getIntent();
username = i.getStringExtra(“userName”);
textView = (TextView)findViewById(R.id.welcome);
textView.setText(username);
