针对对象

下面读取json对象的内容。

}else{

针对数组
[

”geo”: null,
”user”: {
”name”: “json_newb”,

}
},

”geo”: [50.454722, -104.606667],
”user”: {
”name”: “jesse”,
”followers_count”: 2
}
}
]
public List<Message> readJsonStream(InputStream in) throws IOException {
JsonReader reader = new JsonReader(new InputStreamReader(in, “UTF-8”));
try {

} finally {
reader.close();
}
}
public List<Message> readMessagesArray(JsonReader reader) throws IOException {
List<Message> messages = new ArrayList<Message>();
reader.beginArray(); //开始读取数组，此时指向的是最外层的数组
while (reader.hasNext()) {
messages.add(readMessage(reader));//读取数组元素
}
