Android Activity – Navigating From One Screen To Another Screen

In Android, what you see is activity. You interact with Android application through activity. Usually application has more than one activity that are connected each other. In other words, what you see in an Android device is an activity

Refering to Android Developer Site (http://developer.android.com/guide/components/activities.html)
An Activity is an application component that provides a screen with which users can interact in order to do something, such as dial the phone, take a photo, send an email, or view a map. Each activity is given a window in which to draw its user interface. The window typically fills the screen, but may be smaller than the screen and float on top of other windows.

In this tutorial we will show you how to play with activity. We will create 2 activity in which it navigates to each other when a button is clicked.

1. Create Project

We assume you understand creating Android project using eclipse, including create an AVD (Android Virtual Device) and running it. If you never know before you can learn it here

2. Create Layout

Create two xml layout files in “res/layout”
1. activity_first.xml –> Represents Screen 1
2. activity_second.xml –> Represents Screen 2

file : activity_first.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".FirstActivity" >

    <TextView
        android:id="@+id/textViewFirst"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="SCREEN 1" />
    <Button 
        android:id="@+id/buttonFirst"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Go To Second Screen"
        />

</LinearLayout>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical"

tools:context=".FirstActivity" >

<TextView

android:id="@+id/textViewFirst"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="SCREEN 1" />

<Button

android:id="@+id/buttonFirst"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Go To Second Screen"

</LinearLayout>

file : activity_second.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".SecondActivity" >

    <TextView
        android:id="@+id/textViewSecond"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="SCREEN 2" />

    <Button
        android:id="@+id/buttonSecond"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/textViewSecond"
        android:layout_below="@+id/textViewSecond"
        android:text="Go To First Screen" />

</RelativeLayout>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context=".SecondActivity" >

<TextView

android:id="@+id/textViewSecond"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="SCREEN 2" />

<Button

android:id="@+id/buttonSecond"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignLeft="@+id/textViewSecond"

android:layout_below="@+id/textViewSecond"

android:text="Go To First Screen" />

</RelativeLayout>

2. Create Activity

Create two activity classes. Each activity has one layout we have created before
1. FirstActivity.java –> activity_first.xml
2. SecondActivity.java –> activity_second.xml

file : FirstActivity.java

package com.agung.navigateactivity;

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

public class FirstActivity extends Activity implements OnClickListener {

	Button button;
	
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_first);
        
        button=(Button) findViewById(R.id.buttonFirst);
        button.setOnClickListener(this);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.first, menu);
        return true;
    }


	@Override
	public void onClick(View arg0) {
		startActivity(new Intent(FirstActivity. this,SecondActivity.class));
	}
    
}

package com.agung.navigateactivity;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

public class FirstActivity extends Activity implements OnClickListener {

Button button;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_first);

button=(Button) findViewById(R.id.buttonFirst);

button.setOnClickListener(this);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.first, menu);

return true;

}

@Override

public void onClick(View arg0) {

startActivity(new Intent(FirstActivity. this,SecondActivity.class));

}

file : SecondActivity.java

package com.agung.navigateactivity;

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

public class SecondActivity extends Activity implements OnClickListener {
	
	Button button;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_second);
		
		button=(Button) findViewById(R.id.buttonSecond);
		button.setOnClickListener(this);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.second, menu);
		return true;
	}

	@Override
	public void onClick(View v) {
		startActivity(new Intent(SecondActivity.this,FirstActivity.class));
	}

}

package com.agung.navigateactivity;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

public class SecondActivity extends Activity implements OnClickListener {

Button button;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_second);

button=(Button) findViewById(R.id.buttonSecond);

button.setOnClickListener(this);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.second, menu);

return true;

}

@Override

public void onClick(View v) {

startActivity(new Intent(SecondActivity.this,FirstActivity.class));

}

3. Android Manifest

Declare two activity above in AndroidManifest.xml

file : AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.agung.navigateactivity"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="9" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.agung.navigateactivity.FirstActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name="com.agung.navigateactivity.SecondActivity"
            android:label="@string/title_activity_second" >
        </activity>
    </application>

</manifest>

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

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.agung.navigateactivity"

android:versionCode="1"

android:versionName="1.0" >

<uses-sdk

android:minSdkVersion="8"

android:targetSdkVersion="9" />

<application

android:allowBackup="true"

android:icon="@drawable/ic_launcher"

android:label="@string/app_name"

android:theme="@style/AppTheme" >

<activity

android:name="com.agung.navigateactivity.FirstActivity"

android:label="@string/app_name" >

<intent-filter>

</intent-filter>

</activity>

<activity

android:name="com.agung.navigateactivity.SecondActivity"

android:label="@string/title_activity_second" >

</activity>

</application>

</manifest>
