This "loading screen" is called a splash screen.
This is a good stackoverflow on how to change your splash screen (important/key/needed steps listed below). It will also remove the action bar in the splash screen as well.
Key parts of link:
Add Splash Screen Image
First you need a splash screen image. Because Android devices come in
various resolutions, you may want to ship several splash screens as
described in Google's Best Practices for Supporting Multiple Screens.
For simplicity, we'll just ship one here that is 480x800. It should
support most phone sizes pretty well, and Android will scale it as
best it can.
Add the the image/gif you want into your Resources\Drawable
You need to define the spash screen in your layout.xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView id="@+id/splashscreen" android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:src="@drawable/splash"
android:layout_gravity="center"/>
<TextView android:layout_width="fill_parent" <!-- Not needed->-->
android:layout_height="wrap_content"
android:text="Hello World, splash"/> <!--Not Needed -->
</LinearLayout>
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);
}
}
