<string-array name="categories_array">
    <item>Clothes</item>
    <item>Electronics</item>
    <item>Gifts</item>
    <item>Food</item>

    <item>Gifts</item>
    <item>Food</item>
    <item>Books</item>
    <item>Music</item>
    <item>Bags</item>

<string-array name="gifts">

    <item>Gifts</item>
    <item>Food</item>
    <item>Books</item>

现在，如果我的数组名称为"clothes"，我将如何获得它的ID?

Now if i have the array name "clothes" , how would i get it's id?

推荐答案

您可以在下面使用:

int resId = getResources().getIdentifier("nameOfStringResource", "array", getPackageName());

例如:

int resId = getResources().getIdentifier("categories_array", "array", getPackageName());
