ImmutableMap.of（）的替代方案

Question

在我的项目中，我使用以下代码：

        List<Map<String,?>> data = new ArrayList<>();
        data.add(ImmutableMap.of("icon", R.drawable.icon1, "label", getString(R.string.title1)));
        data.add(ImmutableMap.of("icon", R.drawable.icon2, "label", getString(R.string.title2)));
        data.add(ImmutableMap.of("icon", R.drawable.icon3, "label", getString(R.string.title3)));
        data.add(ImmutableMap.of("icon", R.drawable.icon4, "label", getString(R.string.title4)));
        data.add(ImmutableMap.of("icon", R.drawable.icon5, "label", getString(R.string.title5)));

我想知道是否有类似的方法可以不使用guava ImmutableMap，因为我需要从依赖项中删除它。

Answer 1

是的，定义一个类并创建该类的ArrayList。

示例：

public class DataHolder {

   // declare the variables String, int, String, String

   public DataHolder(String str1, int drawableID, String str2, String str3){
     //initialize the class variables with the values passed in constructor
   }


}

然后创建一个ArrayList<DataHolder> ad并将对象添加到其中：

ad.add(new DataHolder("icon", R.drawable.icon1, "label", getString(R.string.title1));
ad.add(new DataHolder("icon", R.drawable.icon2, "label", getString(R.string.title2));
ad.add(new DataHolder("icon", R.drawable.icon3, "label", getString(R.string.title3));
ad.add(new DataHolder("icon", R.drawable.icon4, "label", getString(R.string.title4));
