1.我在我的代码中使用微调器。在微调器中我显示国家代码及其名称。但是在Ui部分我只想显示代码。，当用户从微调器中选择任何国家时。
2.现在我正在考虑国家代码（印度）的价值名称和国家代码的价值（91） 但是我想只显示国家代码值（91），因为我使用了splliting functonality。
但它没有分裂，两个值都显示，我做什么..，我很困惑，我错了， 这是我的代码

嗨代码看起来很好，但你在哪里使用代码的值，好像我们会看到代码
for(String country : CountryCodeArray)
{
String[] parts = country.split(" ");
String code = parts[0];
}
代码的值是for循环的局部内部，你没有使用它....而不是这样做
再次将其存储在数组中并相应地使用!!
你可以做的是
String [] code = new String [CountryCodeArray.length];
并将值存储在名为code的数组中。通过类似
的方式String[] code= new String[CountryCodeArray.length];
for(int i =0;i< CountryCodeArray.length;i++)
{
String[] parts = CountryCodeArray[i].split(" ");
code[i] = parts[0];
}
分别使用数组代码!!
答案 1 :(得分：0)
替换
for(String country : CountryCodeArray)
{
String[] parts = country.split(" ");
String code = parts[0];
}
带
String[] code= new String[CountryCodeArray.length];
for(int i =0;i< CountryCodeArray.length;i++)
{
String[] parts = CountryCodeArray[i].split(" ");
code[i] = parts[0];
}
您可以通过在代码上传递索引来获取国家/地区代码值。
