3. ?我们来写个demo，代码如下：

package com.example.administrator.jsontest;

public class MainActivity extends Activity {

private Button button;

private TextView textView;

private Handler handler = new Handler() {

@Override

public void handleMessage(Message msg) {

switch (msg.what) {

case 0:

String re = (String) msg.obj;

textView.setText(re);

break;

}

}

};

@Override

protected void onCreate(Bundle sedInstanceState) {

super.onCreate(sedInstanceState);

setContentView(R.layout.activity_main);

button = (Button) findViewById(R.id.button);

textView = (TextView) findViewById(R.id.textView);

button.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

Log.i("T", "点击了Button");

sendRequestWithHttpClient();

}

});

}

private void sendRequestWithHttpClient() {

new Thread(new Runnable() {

@Override

public void run() {

HttpURLConnection connection = null;

try {

URL url = new URL("://api.map.baidu/telematics/v3/weather?location=南昌&output=json&ak=8ixCCFzlBB617YX7tONI2P5B&mcode=1C:6B:42:33:E8:A6:DC:A2:11:6E:26:EC:84:BD:42:E3:8E:6B:57:9A;com.example.administrator.jsontest");

connection = (HttpURLConnection) url.openConnection();

connection.setRequestMethod("GET");

connection.setConnectTimeout(5000);

connection.setReadTimeout(5000);

InputStream in = connection.getInputStream();

BufferedReader reader = new BufferedReader(new InputStreamReader(in));

StringBuilder response = new StringBuilder();

String line;

while ((line = reader.readLine()) != null) {

response.end(line);

}

Log.i("T", response.toString()); parseJSONObjectOrJSONArray(response.toString());

} catch (MalformedURLException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

}).start();

}

//解析JSON数据

private void parseJSONObjectOrJSONArray(String jsonData) {

try {

String count = "";

JSONObject jsonObject = new JSONObject(jsonData);

JSONArray jsonArray = jsonObject.getJSONArray("results");

if (jsonArray.length() > 0) {

JSONObject object = jsonArray.getJSONObject(0);

String city = object.optString("currentCity");

JSONArray array = object.getJSONArray("weather_data");

for (int i = 0; i < array.length(); i++) {

JSONObject jsonObject1 = array.getJSONObject(i);

String dateDay = jsonObject1.optString("date");

String weather = jsonObject1.optString("weather");

String wind = jsonObject1.optString("wind");

String temperature = jsonObject1.optString("temperature");

count =count +"\n"+ dateDay + " " + weather + " " + wind + " " + temperature;

Log.i("AAA",count);

}

Message message = new Message();

message.what = 0;

message.obj = count;

handler.sendMessage(message);

}

} catch (JSONException e) {

e.printStackTrace();

}

}

}

天气预报API

中国国家气象局提供了获取所在城市天气预报信息接口。通过这个接口，我们就可以获取天气信息了。

关于获取天气预报的实例参考android学习手册，里面有源码。android学习手册包含9个章节，108个例子，源码文档随便看，例子都是可交互，可运行，源码用android studio目录结构，高亮显示代码，文档都用文档结构图显示，可以快速定位。360手机助手中下载,图标上有贝壳

中国国家气象局天气预报接口总共提供了三个：

://.weather.cn/data/sk/101010100.html

://.weather.cn/data/cityinfo/101010100.html

://m.weather.cn/data/101010100.html

注：上面接口2014.3.4日已不再更新。换成这个：://m.weather.cn/atad/101230201.html。各位看34楼。在此感谢tdwll和黄晓佳cobish。

最详细的信息来自第三个接口。上面url中的101010100是城市代码，这里是北京的城市代码。只需要改变城市代码，就可以得到所在城市的天气信息。笔者在福州，所以选择的城市代码是福州101230101。

在浏览器上输入url：://m.weather.cn/data/101230101.html得到信息，天气信息是json的数据格式，数据如下：

{"weatherinfo":{"city":"福州","city_en":"fuzhou","date_y":"2012年5月14日","date":"","week":"星期一","fchh":"08","cityid":"101230101","temp1":"29℃~23℃","temp2":"26℃~20℃","temp3":"24℃~20℃","temp4":"25℃~20℃","temp5":"24℃~21℃","temp6":"25℃~22℃","tempF1":"84.2℉~73.4℉","tempF2":"78.8℉~68℉","tempF3":"75.2℉~68℉","tempF4":"77℉~68℉","tempF5":"75.2℉~69.8℉","tempF6":"77℉~71.6℉","weather1":"阵雨转中雨","weather2":"中雨转小雨","weather3":"小雨","weather4":"小雨","weather5":"小雨转阵雨","weather6":"阵雨转小雨","img1":"3","img2":"8","img3":"8","img4":"7","img5":"7","img6":"99","img7":"7","img8":"99","img9":"7","img10":"3","img11":"3","img12":"7","img_single":"3","img_title1":"阵雨","img_title2":"中雨","img_title3":"中雨","img_title4":"小雨","img_title5":"小雨","img_title6":"小雨","img_title7":"小雨","img_title8":"小雨","img_title9":"小雨","img_title10":"阵雨","img_title11":"阵雨","img_title12":"小雨","img_title_single":"阵雨","wind1":"微风","wind2":"微风","wind3":"微风","wind4":"微风","wind5":"微风","wind6":"微风","fx1":"微风","fx2":"微风","fl1":"小于3级","fl2":"小于3级","fl3":"小于3级","fl4":"小于3级","fl5":"小于3级","fl6":"小于3级","index":"热","index_d":"天气较热，建议着短裙、短裤、短套装、T恤等夏季服装。年老体弱者宜着长袖衬衫和单裤。","index48":"暖","index48_d":"较凉爽，建议着长袖衬衫加单裤等春秋过渡装。年老体弱者宜着针织长袖衬衫、马甲和长裤。","index_uv":"弱","index48_uv":"最弱","index_xc":"不宜","index_tr":"适宜","index_co":"较不舒适","st1":"27","st2":"21","st3":"24","st4":"18","st5":"22","st6":"18","index_cl":"较不宜","index_ls":"不太适宜","index_ag":"不易发"}}

我们可以解析json数据去得到自己想用的天气信息。

各个天气预报APP数据是怎样接入的，都是统一的来源吗？

://.codeproject/KB/gadgets/WeatherSideShow.aspx

这是codeproject上的一个天气预报桌面应用程序。

可以在://.codeproject/搜索weather关键字，有很多软件。都是开源的。

另外还可以去://sourceforge.net/搜索weather，结果肯定更多。也都是开源的。

这两个站点汇聚了太多人的智慧结晶，肯定有你要的。

首先可以明确一点，所有的气象数据一定都是来自官方的，以非官方名义公布天气数据应该还没有人敢，只是国家天气数据也有不准的时候，所有的公司都面临一个问题，怎么样让自己的数据比竞品更准？1、国家天气数据为什么也会不准？

国家天气数据中的一部分是地面、高空、雷达观测数据，会自动汇总到国家气象信息中心通信台。

一部分是卫星数据，比如中国的风云卫星一般需要20多分钟才能完成全球扫描，所以这部分的数据通常有半小时左右的延迟。

最后是预报数据，气象学上有一些标准模型，跑模型的时间，数据打包传输分发的时间其实是比较长的（由于数据量的关系），比如气象局可能用欧洲中心模式系统的数据，有一些延迟，但是预报的特性就是随着时间不断接近，预测越是准确，很容易理解。就我所知，国家高校的一些研究机构也有自己的模型，也不敢说哪个就一定是最准的。

（一部分信息来自中国气象网）

2、国家天气数据可能是不全面的

有些时候我们想要通过手机传感器获得的经纬度来获取天气数据，或者通过?IP?地址来获取天气数据，这些都是很常见的需求，而国家天气数据的?API?可能不支持。

或者，地方气象台有一些地方的气象数据，它们属于省级气象数据，并不需要上报到国家级，那么自然国家天气数据的?API?不支持，但是地方依旧会公布它们。

亦或者，很多人关心 PM2.5，这些数据不是来自气象局，而是来自环保局，而且环保局还没有空气质量预报，又要从其他机构接入。
