Java Android应用程序是否将内部数组返回为[]或ArrayList内存分配？
您好，我是Java和android新手，我正在尝试解析链接类中的数据，但我不知道如何从一些内部/嵌套的JSONArray中检索JSONObject 我可以从外部JSONArray中检索对象，但看不到如何从StorlineData类中的Java Android应用程序是否将内部数组返回为[]或ArrayList内存分配？,java,android,arrays,parsing,jsonobject,Java,Android,Arrays,Parsing,Jsonobject,您好，我是Java和android新手，我正在尝试解析链接类中的数据，但我不知道如何从一些内部/嵌套的JSONArray中检索JSONObject 我可以从外部JSONArray中检索对象，但看不到如何从StorlineData类中的段内部JSONArray中检索嵌套的JSONArray列表对象 当我尝试解析来自内部/嵌套JSONArray的数据时，响应如下所示： 提前感谢你的帮助 JSON（我无法从trackPointsData和PlacesData获取数据） 主要活动： ... p

这里是解决问题的另一种方法
按照以下步骤操作：
1） 在android项目中导入Jackson库
2） 复制json数据并将其粘贴到文本部分，然后单击查看器选项卡
3） 导入库后，复制JSON数据并将其粘贴到编辑文本框中
- 将源类型设置为JSON
- 将注释样式设置为Jackson 2.x
- 然后单击“预览”
- 它将弹出一个包含所有锅炉板代码的窗口，现在将这些数据以不同的类复制到相应的包中，例如com.android.json.pojo
- 相应地更改类的名称，例如某些类名
4） 现在，使用以下代码从服务器解析获取json字符串
RootElement rootElement = null;
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(Feature.AUTO_CLOSE_SOURCE, true);
// this line is very important
objectMapper.configure(
DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);
try {
rootElement = objectMapper.readValue(result, RootElement.class);
} catch (JsonParseException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
}
例如，RootElement类只是具有与第一个元素相同的json属性的类
@JsonPropertyOrder({
"date",
"summary",
"segments",
"caloriesIdle",
"lastUpdate"
})
您的rootElement现在已解析数据。这里是解决问题的另一种方法
按照以下步骤操作：
1） 在android项目中导入Jackson库
2） 复制json数据并将其粘贴到文本部分，然后单击查看器选项卡
3） 导入库后，复制JSON数据并将其粘贴到编辑文本框中
- 将源类型设置为JSON
- 将注释样式设置为Jackson 2.x
- 然后单击“预览”
- 它将弹出一个包含所有锅炉板代码的窗口，现在将这些数据以不同的类复制到相应的包中，例如com.android.json.pojo
- 相应地更改类的名称，例如某些类名
4） 现在，使用以下代码从服务器解析获取json字符串
RootElement rootElement = null;
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(Feature.AUTO_CLOSE_SOURCE, true);
// this line is very important
objectMapper.configure(
DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);
try {
rootElement = objectMapper.readValue(result, RootElement.class);
} catch (JsonParseException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
}
例如，RootElement类只是具有与第一个元素相同的json属性的类
@JsonPropertyOrder({
"date",
"summary",
"segments",
"caloriesIdle",
"lastUpdate"
})
您的rootElement现在已解析数据。这是您的有效json响应
