我将字符串值传递给此方法。但是我正在获取数组索引绑定的异常,请帮帮我。
public void separateCards(String cards)
{
cardNames+=cards+"-";
String[] parts = cardNames.split("-");
String part1 = parts[0]; // 004
String part2 = parts[1]; // 034556
Toast.makeText(getActivity(), part1,Toast.LENGTH_SHORT).show();
}
}

最佳答案
您将"-"
附加在字符串的末尾,因此在拆分时,您只会得到一个值。
因此,此String part2 = parts[1];
将数组索引抛出异常。
you need to put "-" in between string.
