1、首先你需要注册聚合数据，获取相应的KEY
2、得到相应的key后，我们就可以通过代码来获取数据了，具体代码如下:
/**

*/
public class CaiPumMenueActivity extends Activity {
//配置您申请的KEY
public static final String APPKEY = "82ca66***********49a93e5";
String apiAddress = "http://apis.juhe.cn/cook/query?key=" + APPKEY +
"&menu=午餐&rn=10&pn=3";
/**
* 请求菜谱数据
* @param url:请求 用AsyncTask异步请求
*/
public void readNet(String url) //请求菜谱数据
{
new AsyncTask<String, String, String>() {
StringBuilder sb;
@Override
protected String doInBackground(String... params) {
try {
URL url = new URL(params[0]);
URLConnection connection = url.openConnection(); //建立连接
InputStream inputStream = connection.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader br = new BufferedReader(inputStreamReader);
String line;
sb = new StringBuilder();
while ((line = br.readLine()) != null) {
sb.append(line);
}
br.close();
inputStream.close();
return sb.toString();
} catch (MalformedURLException e) {

4、通过网络获取图片
/**
* //创建新的子线程
* 获取图片
*/
public void ImgThread(final String img) {
new Thread() {
private HttpURLConnection conn;
private Bitmap bitmap;
@Override
public void run() {
super.run();
try {
URL url = new URL(img);
conn = (HttpURLConnection) url.openConnection();
conn.setConnectTimeout(5000);
conn.setRequestMethod("GET");
int code = conn.getResponseCode();
if (code == 200) {
InputStream is = conn.getInputStream();
bitmap = BitmapFactory.decodeStream(is);
Message msg = new Message();
msg.what = 1;
msg.obj = bitmap;
handler.sendMessage(msg);
} else {
Message msg = new Message();
msg.what = 2;
handler.sendMessage(msg);
}
} catch (MalformedURLException e) {
Message msg = new Message();
msg.what = 2;
handler.sendMessage(msg);
e.printStackTrace();
} catch (IOException e) {
Message msg = new Message();
msg.what = 2;
handler.sendMessage(msg);
e.printStackTrace();
}
}
}.start();
}
5、至此数据获取就结束了，很简单！
