Loading Welcome Splash / Spash Screen Example(Android)

In android, when we build an application we may need to display a splash screen ( welcome screen ) for users to intimate some thing & do some other process in background ( like fetching data from DB, Parsing XML , etc.. ).

Splash screen is mainly used in Game Applications. Game application may need to show a splash screen that contains App logo, App name & App author of the game to be displayed for few seconds.

Here we are going to see about a simple splash screen example that displays a textview as splash screen & then move to main activity after the splash screen times up.

splash.xml

Design a splash screen to display.
Splash.xml file used to show as splash screen. It contains a textview with text as "Splash Screen".

[sourcecode language="xml"]
<?xml version="1.0" encoding="utf-8"?>

<LinearLayout android:id="@+id/LinearLayout01"
android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="center" android:background="#6B8AAD">
<TextView android:id="@+id/TextView01" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:textSize="18sp"
android:textStyle="bold" android:textColor="#fff" android:text="Splash Screen"></TextView>
</LinearLayout>

SplashScreenActivity.java

Splash screen activity is used to show splash . Here we use thread to show splash for particular time and then disappear automatically.

package com.android.splash;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

public class SplashScreenActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
/** set time to splash out */
final int welcomeScreenDisplay = 3000;
/** create a thread to show splash up to splash time */
Thread welcomeThread = new Thread() {

int wait = 0;

@Override
public void run() {
try {
super.run();
/**
* use while to get the splash time. Use sleep() to increase
* the wait variable for every 100L.
*/
while (wait < welcomeScreenDisplay) {
sleep(100);
wait += 100;
}
} catch (Exception e) {
System.out.println("EXc=" + e);
} finally {
/**
* Called after splash times up. Do some action after splash
* times up. Here we moved to another main activity class
*/
startActivity(new Intent(SplashScreenActivity.this,
MainScreenActivity.class));
finish();
}
}
};
welcomeThread.start();

}
}

MainScreenActivity.java

This main activity is used to show after the splash times up. From here your Apps start up.

public class MainScreenActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

TextView textView = new TextView(this);
textView.setText("Main Activity");
setContentView(textView);
}
}

That's it..
