Question

由于dex大小，我目前正在将Jackson实现转换为Gson。

我想知道什么是Gson相当于

    public void setNortheast(JsonNode northeast) {
        LatLng northBound = new LatLng(northeast.get("lat").asDouble(), northeast.get("lng").asDouble());
        this.northeast = northBound;
    }

我写道：

public void setNortheast(JsonObject northeast) {
    LatLng northBound = null;
    try {
        northBound = new LatLng(Double.parseDouble(northeast.getString("lat")), Double.parseDouble(northeast.getString("lng")));
    } catch(JsonException e) {
    }
    this.northeast = northBound;
}

但是，它似乎不起作用。我写了正确的代码吗？

提前致谢！：d

我认为你应该使用getDouble而不是Double.parseDouble（“String”）

northeast.getDouble（ “LAT”）

northeast.getDouble（ “LNG”）

修改后的代码如下，

public void setNortheast(JsonObject northeast) {
    LatLng northBound = null;
    try {
        northBound = new LatLng(northeast.getDouble("lat"), northeast.getDouble("lng"));
    } catch(JsonException e) {
    }
    this.northeast = northBound;
}
