Splash screen when open app

We want to show a splash screen when open app.

In folder layout, create a file name spla.xml, set an imageView inside, for example, a brand image.

Create a class name splash, setContentView to spla.xml.

public class splash extends Activity {  

      private static int SPLASH_TIME_OUT = 2000;

      

         @Override

     protected void onCreate(Bundle savedInstanceState) {

           super.onCreate(savedInstanceState);

           setContentView(R.layout.spla);    

         

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

                @Override

         public void run() {

                    

                     // chạy activity chính khi hết 2 giây

        Intent i = new Intent(splash.this, MainActivity.class);

               startActivity(i);        

              finish();

                 }

             }, SPLASH_TIME_OUT);

         }

     }

Change value SPLASH_TIME_OUT = 2000; to show image longer or shorter.

Last, go to AndroidManifest.xml set class splash to first class, declare class MainActivity to below it.

Now we will see splash image show in 2 seconds when open app.
