我在运行应用程序时遇到问题

我有三个活动,包括 - MainActivity.java,一个启动活动,以及另一个名为AirportGuide的活动.

现在,当我在模拟器上运行应用程序时,播放声音,但屏幕是空白的.飞溅三秒后,会打开一个新屏幕,该屏幕也是空白的.在我添加AirportGuide课程之前,应用程序运行正常

这是MainActivity.java

package com.shashank.sharjahinternationalairport;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;

public class MainActivity extends Activity {
ImageButton flightInfoButton;
ImageButton airportGuideButton;
ImageButton visitorInfoButton;
ImageButton saaDcaButton;
ImageButton cargoButton;



@Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    flightInfoButton = (ImageButton) findViewById(R.id.flightInfo);
     visitorInfoButton = (ImageButton) findViewById(R.id.visitorInfo);
     saaDcaButton = (ImageButton) findViewById(R.id.saaDca);        
    cargoButton = (ImageButton) findViewById(R.id.cargo);
   airportGuideButton = (ImageButton) findViewById(R.id.airportGuide);

   airportGuideButton.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View V){

            Intent openAirportGuide = new Intent( MainActivity.this, AirportGuide.class); …
