我在这一行得到了一个java.lang.StringIndexOutOfBoundsException：
timer.start();
在这种方法中：
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch(parent.getId()){
case R.id.list_subject:
quizWorld.setSubject(quizWorld.getSubjects().get((int) id));
ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this, R.layout.list_item, R.id.listItem, quizWorld.getCategories());
list_category.setAdapter(adapter2);
state = GameState.Category;
viewSlider.next();
break;
case R.id.list_category:
quizWorld.setCategory(quizWorld.getCategories().get((int) id));
quizWorld.swapQuestion();
state = GameState.Running;
timer.start();
viewSlider.next();
break;
}
}
当我打电话给＆＃34; timmer.start（）;＆＃34;在其他任何方法的其他地方它的工作。即使我使用调试器，我也没有错误。仅在此特定方法中且仅在正常模式下不在调试器模式下。

你有什么想法吗？
答案 0 :(得分：1)
这可能不是完整的怀疑答案，但对于评论来说太长了，所以请从downvoting中选择。我认为错误在这里：
milliseconds = milliseconds.substring(milliseconds.length()-3, milliseconds.length()-2);
如果你得到毫秒＆lt; = 1，那么你将毫秒设置为＆＃34; 00＆＃34;。然后，不可能获得milliseconds.length-3的子字符串。所以一个解决方案，不是很干净，而是一个解决方案，就是这样做：
if(milliseconds.length()>=3){
milliseconds = milliseconds.substring(milliseconds.length()-3, milliseconds.length()-2);
}
只需设置if语句，所以你可以肯定，只有当字符串足够长才能获得这样的子字符串时才会调用它。
