我正在为coordinates
创建POJO而堆叠。
public class Geometry {
String type;
Coordinates coordinates;
}
public class Coordinates {
// What need to be here???
}
我被卡住了,因为我没有理解我如何解析coordinates
标签。我怎样才能正确实现POJO的结构?
答案 0 :(得分:1)
你不会看到钥匙,因为钥匙不是钥匙,而是价值。 (我真的没有看到你在坐标中拥有嵌套数组的意义。)
要解析coordinate
,您将拥有类似的内容
public class Geometry{
private ArrayList<ArrayList<ArrayList<Double[]>>> coordinates;
//create getter and setter methods
}
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:我可能遗失或超过ArrayList
。请仔细检查一下。
答案 1 :(得分:0)
public class Coordinates {
float latitude;
float longitude;
}
public class CoordinatesList1 {
ArrayList<Coordinates> list1;
}
public class CoordinatesList2 {
ArrayList<CoordinatesList1> list2;
}
public class Geometry {
String type;
ArrayList<CoordinatesList2> coordinates;
}
Gson gson = new Gson();
CoordinatesList2[] myTypes = gson.fromJson("input.json", Geometry.class);
