我在运行应用时遇到问题
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，但屏幕为空白。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，该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);
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

这是启动活动
package com.shashank.sharjahinternationalairport;
import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
public class Splash extends Activity{
MediaPlayer splashSound;
@Override
protected void onCreate(Bundle splashScreen) {
// TODO Auto-generated method stub
super.onCreate(splashScreen);
setContentView(R.layout.splash);
splashSound = MediaPlayer.create(Splash.this, R.raw.splashsound);
splashSound.start();
Thread timer = new Thread(){
public void run(){
try{
sleep(3200);
} catch (InterruptedException e){
e.printStackTrace();
}finally{
Intent openMainActivity = new Intent("com.shashank.sharjahinternationalairport.MAINACTIVITY");
startActivity(openMainActivity);
}
}
};
timer.start();
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
splashSound.release();
finish();
}
}

重新启动您的模拟器。在硬件设备上测试它，它可能会工作。
