Question

我以这种方式得到Api的回应响应是：

}

这是纬度和经度

我想在以这种方式传递参数的Google地图上绘制折线

LatLng a = new LatLng(24.876483014725, 66.933707682325);
LatLng a = new LatLng(24.7983557697, 66.885708125774);
LatLng a = new LatLng(24.862141543725, 66.943130493164);

那么，我解析我的回复吗？

Answer 1

在 kotlin 中，您可以执行以下操作：

val points: List<LatLng> = JSONObject(data)["path"].toString()
    .replace("{", "")
    .replace("}", "")
    .replace("\n","")
    .replace(" ","")
    .trim()
    .split(",")
    .onEach { it.trim() }
    .chunked(2)
    .map { LatLng(it[0].toDouble(), it[1].toDouble()) }

在 Java 中：

String[] pts = new JSONObject(data).getString("path")
.replace("\n","")
.replace(" ","")
.replace("{","")
.replace("}","")
.split(",");
ArrayList<LatLng> list = new ArrayList<>();
for(int i=0;i<pts.length;i=i+2){
    double lat = Double.parseDouble(pts[i]);
    double lng = Double.parseDouble(pts[i+1]);
    list.add(new LatLng(lat,lng));
}

Answer 2

最好使用Double lat和Double lng模型的列表从API发送值。并将此列表发送到地理点之间的线的绘制功能。

如果您不能执行此操作。我建议创建一个latlng模型的列表，并将偶数json的单元格放置到lat模型的lng中，并将奇数json的单元格放置到latlng模型中，并将其添加到{{ 1}}语句。

注意：：将您的JSON作为字符串和for获取，然后您将可以访问数组的偶数和奇数单元格。

作为回应，请根据我的要求获取单个对象的解析方法
