How to create a timer in Android Studio?

So I have created the splash screen for my application, it displays but does not go to the homepage, (Homepage file: homepage.xml) how do I make a timer to go off and then take the user from splash to homepage in 5 secs?

This is my code:

package everingapplications.fishinglife;

import android.app.Activity;
import android.os.Bundle;

/**
 * Created by Doctors on 8/4/2015.
 */
public class Splash extends Activity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splashscreen);

    }
}

Hi, You have to add this code to the "onCreate" of the splash screen:

package everingapplications.fishinglife;

import android.app.Activity;
import android.os.Bundle;

public class Splash extends Activity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splashscreen);
        /* Inset This Code Here */

        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent intent = new Intent(Splash.this, homepage.class);
                startActivity(intent);
                finish();
            }
        }, 5000);
    }
}
