我正在为 coordinates 创建 POJO 。
public class Geometry {
String type;
Coordinates coordinates;
}
public class Coordinates {
// What need to be here???
}
我陷入困境，因为我不明白如何解析 coordinates 标签。如何正确实现POJO的结构？
Gson and deserializing an array of objects with arrays in it
最佳答案
您看不到键，因为它们不是键，而是值。 (我真的不明白在坐标中拥有嵌套数组的意义)。
要解析坐标，您将得到类似的内容
public class Geometry{
private ArrayList<ArrayList<ArrayList<Double[]>>> coordinates;
//create getter and setter methods
}
要解析它，
// Get Geometry object (however you do it)
// Then use the getter method to get coordinates variable
// Parse the nested arrays
ArrayList<Double[]> values = geometry.getCoordinates().get(0).get(0).get(0);
// You can now access the values, e.g.
Double[] firstArray = values.get(0);
注意:我可能缺少或超出了 ArrayList。只需仔细检查即可。
