如何从 Android 中的微调器中删除 4 和 5 索引

Question

您好，在下面的代码中，我实现了一个微调器。从 Api 我正在获取字符串并添加到数组列表，然后显示一个微调器。

现在要从微调器列表中删除 4 和 5 索引，然后要显示微调器。

它给我一个错误

java.lang.IndexOutOfBoundsException：索引：4，大小：1

Answer 1

尝试这样的事情：

value = pickListValues1.getValue();
 label=pickListValues1.getLabel();
 sales_stagenames.add(value);
 ArrayList<String> salesstages=new ArrayList<>();
for(int i=0;i<= sales_stagenames.size();i++){
if((i!=4)&&(i!=5))                                                      salesstages.add(sales_stagenames.get(i));}
