不幸的是，应用程序已停止，随机数字崩溃

但我实现了在代码中没有错误，但是当我尝试在模拟器中执行它说非常幸运的应用程序已停止。问题必须在这一部分，因为它仅停止时klassenNr = 6不幸的是，应用程序已停止，随机数字崩溃

int zufallsNr1; 
int zufallsNr2 = 300; 
int zufallsNr3 = 300; 
int zufallsNr4 = 300; 
int zufallsNr5 = 300; 

if (klassenNr == 6) { 
    Random zufall = new Random(); 
    int zufallsNr1 = zufall.nextInt(name[4].length); 
    while (zufallsNr1 == zufallsNr2 && zufallsNr2 == 300) { 
     zufallsNr2 = zufall.nextInt(name[4].length); 
    } 
    while (zufallsNr3 == zufallsNr2 && zufallsNr3 == zufallsNr1 && zufallsNr3 == 300) { 
     zufallsNr3 = zufall.nextInt(name[4].length); 
    } 
    while (zufallsNr4 == zufallsNr2 && zufallsNr4 == zufallsNr1 && zufallsNr4 == zufallsNr3 
       && zufallsNr4 == 300) { 
     zufallsNr4 = zufall.nextInt(name[4].length); 
    } 
    while (zufallsNr5 == zufallsNr2 && zufallsNr5 == zufallsNr1 && zufallsNr5 == zufallsNr3 
       && zufallsNr5 == zufallsNr4 && zufallsNr5 == 300) { 
     zufallsNr5 = zufall.nextInt(name[4].length); 
    } 

    valuelist = new String[] { name[4][zufallsNr1], 
      name[4][zufallsNr2], name[4][zufallsNr3], 
      name[4][zufallsNr4], name[4][zufallsNr5] }; 

} else { 
    if (klassenNr == 5) { 
     valuelist = topographienamen; 
    } else { 
     valuelist = name[klassenNr]; 
    } 
}

300比名得多[4]。长度

logcat的：

将您的堆栈跟踪从log cat复制到这里。 – Trinimon

也许愚蠢的问题，但...怎么样？ – user3047349

FuenfteActivity的449行是什么？那里发生了错误。 – tcooc
