Splash screen in Android Application

Question

I am modifying an open source application and want to add a splash screen to it, Can some one help me in it?

When the application starts a black screen appears for 2

Answer 1

Don't forget to consider that the user might want to quit your app before the splash-delay is over. So clear any pending runnables/messages when the user exits your app.

Example can be found here

Splash activity

public class LaunchScreen extends Activity {

  public static final long TIME = 3000;

  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.logo);

    Protocol.getInstance(this);

    Thread welcomeThread = new Thread() {

        @Override
        public void run() {
            try {
                sleep(TIME);
            } catch (Exception e) {
                Log.e(getClass().getName(), e.toString());
            } finally {
                startActivity(new Intent(LaunchScreen.this,MainScreen.class));
                finish();
            }
        }
    };
    welcomeThread.start();
  }
}

logo.xml file:

  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="right"
>
<ImageView
android:id="@+id/logo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/logo"
android:layout_centerInParent="true"
>
</ImageView>
</RelativeLayout>

in AndroidManifest :

activity android:name=".LaunchScreen">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".MainScreen" android:label="@string/app_name" ></activity>

Use class SplashScreen as under

public class Splashscreen extends Activity {

private static final int SPLASH_DISPLAY_TIME = 3000; /* 3 seconds */

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    new Handler().postDelayed(new Runnable() {

        public void run() {

            Intent mainIntent = new Intent(Splashscreen.this,
                    MainActivity.class);
            Splashscreen.this.startActivity(mainIntent);

            Splashscreen.this.finish();
            overridePendingTransition(R.anim.mainfadein,
                    R.anim.splashfadeout);
        }
    }, SPLASH_DISPLAY_TIME);
}

}

**Add mainfadein.xml & splashfadeout.xml in res->anim folder

mainfadein.xml**

    <?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:fromAlpha="0.0"
        android:toAlpha="1.0"
        android:duration="1000">
</alpha>

splashfadeout.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/decelerate_interpolator"
        android:zAdjustment="top"
        android:fromAlpha="1.0"
        android:toAlpha="0.0"
        android:duration="1000" >
</alpha>

and add splash.xml just Add an ImageView and set its background as screen & add image of urchoice in layout

And make Splashscreen class as Launcher and make all other class as HOME in manifest file
