ここで、JSON を GSON で処理する必要がありますが、「ジオメトリ」のセクションのみが必要です。場所 (緯度、経度) が必要です。このjsonをPOJOにバインドするにはどうすればよいですか? 私はそのようなことを意味します

public class GoogleMapLocation
{
    @SerializedName("lat")
    private double latitude;

    @SerializedName("lng")
    private double longitude;

    public double getLatitude()
    {
        return latitude;
    }

    public void setLatitude(final double latitude)
    {
        this.latitude = latitude;
    }

    public double getLongitude()
    {
        return longitude;
    }

    public void setLongitude(final double longitude)
    {
        this.longitude = longitude;
    }
}

その後

GoogleMapLocation gml = gson.fromJson(jsonReader, GoogleMapLocation.class);

これは機能するはずです（getter、setter、...明確にするために省略されていますが、エラー防止ではありません）：

public class GoogleMapLocation {
    List<Result> results;

    String status;
}

public class Result {
    @SerializedName("address_components")
    private List<AddressComponent> addressComponents;

    @SerializedName("formatted_address")
    private String formattedAddress;

    private Geometry geometry;

    @SerializedName("partial_match")
    private String partialMatch; // not sure of the type

    private List<String> types;
}

public class AddressComponents {
    @SerializedName("long_name")
    private String longName;

    @SerializedName("short_name")
    private String shortName;

    private List<String> types;
}

public class Geometry {
    LatLng location;

    Viewport viewport;

    Viewport bounds;

    @SerializedName("location_type")
    String locationType;
}

public class LatLng {
    @SerializedName("lat");
    private double latitude;

    @SerializedName("lng");
    private double longitude;
}

public class Viewport {
    private LatLng northeast;

    private LatLng southwest;
}

公式ドキュメントを参照してください。

status編集: 一部のフィールドは列挙型 ( 、...)として宣言することもできることに注意してください。
