Far apparire un Button dopo una Splashscreen.

Salve a tutti. Come da titolo, vorrei implementare un Button che appare solo dopo che la Splashscreen scompare via. Come si può fare?

Vi posto il codice della Splashscreen.

Codice:

package com.package.lamiapp;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;

public class Lamiapp extends Activity {
   
   private static final int STOPSPLASH = 0;
   //time in milliseconds
   private static final long SPLASHTIME = 3000;
   
   private ImageView splash;
   
   
   //handler for splash screen
   private Handler splashHandler = new Handler() {
      /* (non-Javadoc)
       * @see android.os.Handler#handleMessage(android.os.Message)
       */
	  
      @Override
      public void handleMessage(Message msg) {
    	 switch (msg.what) {
         case STOPSPLASH:
            //remove SplashScreen from view
            splash.setVisibility(View.GONE);
            break;
         }
         super.handleMessage(msg);
      }
   };
   
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.lamiapp_layout);
         splash = (ImageView) findViewById(R.id.splashlogo);
         Message msg = new Message();
         msg.what = STOPSPLASH;
         splashHandler.sendMessageDelayed(msg, SPLASHTIME);     
    }
}

Layout:

Codice:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/splashlogo"
        android:layout_width="230dp"
        android:layout_height="312dp"
        android:src="@drawable/logosito" />

</LinearLayout>
