我的应用程序确实打开了启动画面并播放了背景音乐..但之后它应该打开列表活动但它崩溃了 我曾尝试使用其他几乎一切的名称运行相同的程序,但当我重新输入程序时它崩溃了..我已经清理和刷新,甚至没有任何区别
我的java文件
Splash.java:
package com.alpha.beta;
import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
public class Splash extends Activity {
MediaPlayer ourSong;
@Override
protected void onCreate(Bundle beta) {
super.onCreate(beta);
setContentView(R.layout.splash);
ourSong = MediaPlayer.create(Splash.this, R.raw.splash_sound);
ourSong.start();
Thread timer = new Thread(){
public void run(){
try {
sleep(5100);
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
Intent openStartingPoint = new Intent("com.alpha.beta.MENU");
startActivity(openStartingPoint);
}
}
};
timer.start();
}
@Override
protected void onPause() {
super.onPause();
ourSong.release();
finish();
}
}

试试这种方式
Intent openStartingPoint = new Intent(Splash.this,Menu.class);
startActivity(openStartingPoint);
修改: - 有时候问题是没有获取该活动的上下文。这就是为什么你可能会因为ActivityNotFoundException
而获得异常。

只是一个想法。在意图中,您已将类名指定为 MENU ,但在清单中,它是菜单。尝试更改它,区分大小写可能是一个问题。同时为菜单类定义操作。操作名称应为 VIEW 。
如果是,则活动(启动和菜单)是否属于同一个包 然后尝试
Intent i = new Intent(Splash.this, Menu.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
