How do I make a splash screen? [closed]

Answer 1

A Splash Screnn, by default, does not automatically make your Application look more professional. A professionally designed Splash Screen has a possibility of making your Application look more professional, but if you do not know how to write one then how professional will the rest of your Application actually be.

About the only reason (excuse) to have a Splash Screen is because you are doing a massive amount of Calculations or are waiting for GPS/WiFi to startup because your Application relies on that prior to it starting. Without the result of those Calculations or access to GPS/WiFi (etc.) your Application is dead in the water, thus you feel you need a Splash Screen, and MUST block the view of the Screen for any other running Programs (including the Background).

Such a Splash Screen ought to look like your Full Screen Application to give the impression that it has already initialized, then after the lengthy calculations are completed the final details could be filled in (the Image tweaked). The chance of that being the case or that it is the only way the Program could be designed is mighty small.

It would be better to allow the User (and the rest of the OS) to do something else while they wait rather than design your Program to be dependant on something that will take a while (when the duration of the wait is uncertain).

There are Icons on your Phone already that say that GPS/WiFi is starting. The time or space taken up by the Splash Screen could be spent loading pre-calculations or actually doing the Calculations. See the first Link below for the problems you create and what must be considered.

If you absolutely must wait for these Calculations or GPS/WiFi it would be best to simply let the Application start and have a pop-up that says that it is necessary to wait for the Calculations (a TEXTUAL "Initializing" Message is fine). The wait for GPS/WiFi is expected (if they were not enabled in another Program already) so announcing their wait times are unnecessary.

Remember that when the Splash Screen starts your Program IS actually running already, all you are doing is delaying the use of your Program and hogging the CPU/GPU to do something that most do not feel is necessary.

We had better really want to wait and see your Splash Screen every time we start your Program or WE will not feel it is very professionally written. Making the Splash Screen FULL Screen and a duplicate of the actual Program's Screen (so we think it is initialized when in fact it has not) MIGHT accomplish your goal (of making your Program look more professional) but I would not bet much on that.

So there is a good reason not to do it but IF you are certain that somehow your situation falls outside those examples then the means to do it is given above. Be certain that it really does make your Application look more professional or you have defeated the only reason you gave for doing this.

It is like a YouTube Channel that starts every Video with a lengthy Graphic Intro (and Outro) or feels the need to tell a Joke or explain what happened during the past week (when it is not a Comedy or LifeStyles Channel). Just show the show ! (Just run the Program).

The answers above is very good, but I would like to add something else. I am new to Android, I met these problem during my development. hope this can help someone like me.

1. The Splash screen is the entry point of my app, so add the following lines in AndroidManifest.xml.

       <activity
           android:name=".SplashActivity"
           android:theme="@android:style/Theme.DeviceDefault.Light.NoActionBar">
           <intent-filter>
               <action android:name="android.intent.action.MAIN" />
               <category android:name="android.intent.category.LAUNCHER" />
           </intent-filter>
       </activity>
   

2. The splash screen should only show once in the app life cycle, I use a boolean variable to record the state of the splash screen, and only show it on the first time.

   public class SplashActivity extends Activity {
       private static boolean splashLoaded = false;
   
       @Override
       public void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
   
           if (!splashLoaded) {
               setContentView(R.layout.activity_splash);
               int secondsDelayed = 1;
               new Handler().postDelayed(new Runnable() {
                   public void run() {
                       startActivity(new Intent(SplashActivity.this, MainActivity.class));
                       finish();
                   }
               }, secondsDelayed * 500);
   
               splashLoaded = true;
           }
           else {
               Intent goToMainActivity = new Intent(SplashActivity.this, MainActivity.class);
               goToMainActivity.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
               startActivity(goToMainActivity);
               finish();
           }
       }
   }
   

happy coding!

Splash screens should not be loaded from a layout file, there might still be some lag when loading it.

The best way is to create a Theme just for your SplashScreenActivity and set the android:windowBackground to a drawable ressource.

https://www.bignerdranch.com/blog/splash-screens-the-right-way/

In a nutshell:

Declare your SplashScreenActivity in the manifest:

<activity
        android:name=".activities.SplashScreenActivity"
        android:theme="@style/SplashTheme"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

In your SplashScreenActivity.java:

@Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Intent intent = new Intent(this, MainActivity_.class);
    startActivity(intent);
    finish();

}

Next create the ressource for the background window of your theme:

<style name="SplashTheme" parent="Theme.Bumpfie.Base">
    <item name="android:windowBackground">@drawable/splash</item>
</style>

Drawable file splash.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@android:color/white"/>
    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/app_logo"/>
    </item>
</layer-list>

Answer 4

The Stopping on the Splash screen for 4's 5's unnecessarily doesn't make much sense. It's Ok if you loading something in background else follow this approach to implement splash screen:- Implementing a splash screen the right way is a little different than you might imagine. The splash view that you see has to be ready immediately, even before you can inflate a layout file in your splash activity.

So you will not use a layout file. Instead, specify your splash screen’s background as the activity’s theme background. To do this, first, create an XML drawable in res/drawable.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:drawable="@color/gray"/>

    <item>
        <bitmap
            android:gravity="center"
            android:src="@mipmap/ic_launcher"/>
    </item>

</layer-list>

Here, I’ve set up a background color and an image.

Next, you will set this as your splash activity’s background in the theme. Navigate to your styles.xml file and add a new theme for your splash activity:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

    <style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowBackground">@drawable/background_splash</item>
    </style>

</resources>

In your new SplashTheme, set the window background attribute to your XML drawable. Configure this as your splash activity’s theme in your AndroidManifest.xml:

<activity
    android:name=".SplashActivity"
    android:theme="@style/SplashTheme">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

Finally, SplashActivity class should just forward you along to your main activity:

     public class SplashActivity extends AppCompatActivity {

             @Override
             protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);

               Intent intent = new Intent(this, MainActivity.class);
               startActivity(intent);
               finish();
    }
}

Answer 5

In my case I didn't want to create a new Activity only to show a image for 2 seconds. When starting my MainAvtivity, images gets loaded into holders using picasso, I know that this takes about 1 second to load so I decided to do the following inside my MainActivity OnCreate:

splashImage = (ImageView) findViewById(R.id.spllll);

    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

    int secondsDelayed = 1;
    new Handler().postDelayed(new Runnable() {
        public void run() {
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
            splashImage.setVisibility(View.GONE);

        }
    }, secondsDelayed * 2000);

When starting the application the first thing that happens is the ImageView gets displayed and the statusBar is removed by setting the window flags to full screen. Then I used a Handler to run for 2 seconds, after the 2 seconds I clear the full screen flags and set the visibility of the ImageView to GONE. Easy, simple, effective.

Create a Activity, let us Activity named 'A', then create a xml file called myscreen.xml, in that set a the splash screen image as background, and then use count down timer to navigate from one Activtity to another. To know how to use Count Down timer see my answer in this question TimerTask in Android?
