我在运行应用程序时遇到问题

我有三个活动，分别是MainActivity.java，启动活动和另一个名为AirportGuide的活动。

现在，当我在模拟器上运行该应用程序时，正在播放启动音，但屏幕空白。飞溅三秒钟后，将打开一个新屏幕，该屏幕也为空白。在我添加AirportGuide类之前，该应用程序运行良好

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);
           startActivity(openAirportGuide);

        }
      });
 }


 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
 }

}

这是AndroidManifest

            <category android:name="android.intent.category.DEFAULT" />
