Android studio tutorial basic: Know Activity Android Further

Android studio tutorial basic in the previous article was about how we know a programming language Activity in android, which at the article I've included an example is to create a project PindahActivity. From the previous article I hope you have understood the basic concept of an Activity that move from one screen to another screen. On this occasion I still continued tutorial discusses the basic android namely Activity where this time when the user moves from the first to the Activity Activity both then will send the value derived from the input that was in the first Activity.

Of that I ask you to open a studio android application and then create a new project with the name KirimNilaiActivity, where the project is eventually contained KirimNilaiActivity java and xml file as follows:

• PertamaActivity.java
• KeduaActivity.java
• activity_pertama.xml
• activity_kedua.xml
• AndroidManifest.xml

Source code PertamaActivity.java

package com.dsoccerupdate.kirimnilaiactivity;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class PertamaActivity extends Activity {
    EditText inputName;
    EditText inputEmail;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_pertama);

        inputName = (EditText) findViewById(R.id.name);
        inputEmail= (EditText) findViewById(R.id.email);
        Button btnNextScreen = (Button) findViewById(R.id.btnNextScreen);

        btnNextScreen.setOnClickListener(new View.OnClickListener() {
            public void onClick(View arg0) {
                Intent nextScreen = new Intent(getApplicationContext(), KeduaActivity.class);
                nextScreen.putExtra("name",
                        inputName.getText().toString());
                nextScreen.putExtra("email",
                        inputEmail.getText().toString());
                startActivity(nextScreen);
            }
        });
    }
}

Source code KeduaActivity.java

package com.dsoccerupdate.kirimnilaiactivity;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class KeduaActivity extends Activity {
    @Override

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_kedua);
        TextView txtName = (TextView) findViewById(R.id.txtName);
        TextView txtEmail = (TextView) findViewById(R.id.txtEmail);
        Button btnClose = (Button) findViewById(R.id.btnClose);

        Intent i = getIntent();
        String name = i.getStringExtra("name");
        String email = i.getStringExtra("email");

        txtName.setText(name);
        txtEmail.setText(email);

        btnClose.setOnClickListener(new View.OnClickListener() {
            public void onClick(View arg0) {
                finish();
            }
        });
    }
}

Similarly, the advanced tutorial of Activity in android programming languages, hopefully this short article can provide a better understanding of the Activity. Look forward to the continuation of the basic studio android tutorial where the next opportunity I will discuss about the fragment in android. Visit the blog tutorial continues android studio, because there will always be the latest news about the world of Android, especially tutorials to develop applications based on Android.
