如何在Android上ArrayList中每个元素的末尾添加逗号 [英] How to add a comma at the end of every element in ArrayList On Android

问题描述

在我的应用程序中，我想使用此库来显示ArrayList项目.
我来自服务器的ArrayList:

In my application I want use this Library for show ArrayList items.
My ArrayList from server:

"genres": [
      "Action",
      " Comedy",
      " Family"
    ]

我为表演物品写以下代码:

I write below code for show Items:

private String[] mostlyMatchedKeywordsStrings = serialResponse.getData().getGenres();
private List<String> cloudChipList = new ArrayList<>();

for (String str : mostlyMatchedKeywordsStrings) {
    cloudChipList.add(str);

    if (cloudChipList.size() > 0) {
       infoSerialFrag_GenreChips.addChip(str);
    }
}

给出的结果为:

Ganre:动作喜剧大家庭

Ganre : Action Comedy Family

但是我想要这样:

Ganre:动作，喜剧，家庭

Ganre : Action , Comedy , Family

推荐答案

您可以使用for循环这样尝试吗:

Can you try this using for loop like this:

已

private String[] mostlyMatchedKeywordsStrings;
    private List<String> cloudChipList = new ArrayList<>();

    mostlyMatchedKeywordsStrings = serialResponse.getData().getGenres();

    for (String str : mostlyMatchedKeywordsStrings) {
        cloudChipList.add(str);
    }
    if (cloudChipList.size() > 0) {
        for (int i = 0; i < cloudChipList.size(); i++) {

            if (i == (cloudChipList.size() - 1)) //true only for last element
                infoSerialFrag_GenreChips.add(cloudChipList.get(i));

            else
                infoSerialFrag_GenreChips.add(cloudChipList.get(i) + ","); //this will execute for 1st to 2nd last element
        }
    }
