How to easily switch from one activity to another activity in designing an Android application using Eclipse

Question

Tell me an easy way to do it while opening the application with the name and then the regular activity

Answer 1

By doing this you can start one activity from another:

Intent myIntent = new Intent(CurrentActivity.this, NextActivity.class);
myIntent.putExtra("key", value); //Optional parameters
CurrentActivity.this.startActivity(myIntent);

EDIT:

if you need a splash screen, here is a solution for it:

How do I make a splash screen?

/** 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);
}
