android 百度天气接口

百度天气接口

之前有篇随笔是说中国气象的天气接口的，但那个接口不是很稳定，用一段时间过后就会获取不到数据了。

1.最近看到百度有个天气接口，拿来用了用，感觉挺好的，这里就说说这个接口了

百度提供天气预报查询接口API，可以根据经纬度/城市名查询天气情况。

接口说明

根据经纬度/城市名查询天气的结果

接口示例

http://api.map.baidu.com/telematics/v3/weather?location=北京&output=json&ak=yourkey

百度ak申请地址：http://lbsyun.baidu.com/apiconsole/keyAK申请到以后，就可以直接用这个接口了。

接口参数说明

返回结果

2.在网页上查看数据接口的数据XML格式的数据：

            ]
        }
    ]
}

下面用一个demo来获取天气的数据(以获取json为例 就不解析了)：

　　手机上获取到的数据:

部分代码：

 1 public class MainActivity extends Activity {
 2
 3     private TextView showTextView;
 4
 5     private AsyncHttpClient mAsyncHttpClient;
 6
 7     private String Url = "你的百度天气接口";
 8
 9     @Override
10     protected void onCreate(Bundle savedInstanceState) {
11         super.onCreate(savedInstanceState);
12         setContentView(R.layout.activity_main);
13
14         showTextView = (TextView) findViewById(R.id.showTextView);
15
16         mAsyncHttpClient = new AsyncHttpClient();
17
18         mAsyncHttpClient.get(Url, null, new JsonHttpResponseHandler() {
19
20             @Override
21             public void onSuccess(JSONObject result) {
22                 super.onSuccess(result);
23
24                 showTextView.setText(result.toString());
25             }
26
27             @Override
28             public void onFinish() {
29                 // TODO Auto-generated method stub
30                 super.onFinish();
31             }
32
33         });
34
35     }
36 }
