在我正在使用的应用程序中listview，我也在进行json解析。根据颜色代码，我得到它并将其设置为带圆形的 ShapeDrawable，但问题是我在每个列表项中获取最后一个颜色代码数组的值，以下是我的 json 响应和代码有人可以帮助我吗？
我的 Json 响应
[
{
"id_product": "1445",
"name": "Stylish Sleeveless Leather Vest",
"price": 1990,
"discount": 199,
"colors": [
"#000000",
"#7E3517",
"#C85A17"
],
"sizes": [
"Medium",
"Large",
"Small"
],
"img_url": "",
"popup_images": [
]
},
{
"id_product": "1427",
"name": "Stylish Slim Fit Designed PU Leather Jacket",
"price": 3290,
"discount": 329,
"colors": [
"#000000",
"#C85A17"
],
"sizes": [
"Large",
"Medium",
"Small"
],
"img_url": "",
"popup_images": [
]
}
]
现在的问题是我的每个列表项中只有两种颜色，颜色是以下两种
"colors": [
"#000000",
"#C85A17"
],
