有人可以帮助我吗？我正在制作一个简单的 Android 应用程序，它具有启动画面和带有按钮的主菜单，这应该会导致另一个“页面”并且可能会播放声音。该应用程序启动一秒钟，出现启动画面，然后应用程序崩溃。我还注意到按钮加载另一个页面需要一段时间：
我认为这条线与它有关：

这些是不断出现的红色错误：

如果需要，我可以发布更多信息，提前谢谢！
我的 MainActivity.java ：
package com.example.prva;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
public class MainActivity extends Activity {
MediaPlayer MPlayer;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
MPlayer = MediaPlayer.create(this, R.raw.splash);
MPlayer.start();
Thread tajmer = new Thread(){
public void run(){
try{
int tajmer = 0;
while(tajmer == 0)
{
sleep(3500);
tajmer = tajmer +1;
}
startActivity(new Intent(MainActivity.this, Meni_Splash.class));
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally{
finish();
}
}
};
tajmer.start();
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
MPlayer.release();
}
@Override

// TODO Auto-generated method stub
super.onPause();
MPlayer.pause();
}
@Override

// TODO Auto-generated method stub

}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
这是一个 Meni_Splash.java 代码：
package com.example.prva;
import android.app.Activity;
import android.content.Intent;

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Button click sound
final MediaPlayer ButtonClick = MediaPlayer.create(this, R.raw.button1);
Button btnv = (Button) findViewById(R.id.buttonv);
btnv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
startActivity(new Intent("com.example.prva.BUTTONVELIKI"));
ButtonClick.start();
}
});
Button btn3 = (Button) findViewById(R.id.buttonplay);
btn3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
startActivity(new Intent("com.example.prva.BUTTONPLAY"));
ButtonClick.start();
