Old answer:
HOW TO: Simple splash screen
This answers shows you how to display a splash screen for a fixed amount of time when your app starts for e.g. branding reasons. E.g. you might choose to show the splash screen for 3 seconds. However if you want to show the spash screen for a variable amount of time (e.g. app startup time) you should check out Abdullah's answer https://stackoverflow.com/a/15832037/401025. However be aware that app startup might be very fast on new devices so the user will just see a flash which is bad UX.
First you need to define the spash screen in your layout.xml
file
And your activity:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
public class Splash extends Activity {
/** Duration of wait **/
private final int SPLASH_DISPLAY_LENGTH = 1000;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.splashscreen);
/* New Handler to start the Menu-Activity
* and close this Splash-Screen after some seconds.*/
new Handler().postDelayed(new Runnable(){
@Override
public void run() {
/* Create an Intent that will start the Menu-Activity. */
Intent mainIntent = new Intent(Splash.this,Menu.class);
Splash.this.startActivity(mainIntent);
Splash.this.finish();
}
}, SPLASH_DISPLAY_LENGTH);
}
}
Thats all ;)
