导入第三方jar包

    implementation 'com.alibaba:fastjson:1.2.49'
    implementation 'com.alibaba:fastjson:1.1.70.android'

创建Http类

public class HttpConnection {


    public static String getHttpRequest(String urlString){
        URL url;
        InputStream in = null;
        HttpURLConnection conn = null;

        ByteArrayOutputStream out = new ByteArrayOutputStream();
        try {
            url = new URL(urlString);
            conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");
            conn.setConnectTimeout(5000);
            conn.setDoInput(true);
            conn.connect();

            if(conn.getResponseCode() == HttpsURLConnection.HTTP_OK){
                in = conn.getInputStream();
                int len =0;
                byte[] buffer = new byte[1024];
                while((len= in.read(buffer))!=-1){
                    out.write(buffer, 0, len);
                }
                return out.toString();
            }
        } catch (MalformedURLException e) {

            e.printStackTrace();
        } catch (ProtocolException e) {

            e.printStackTrace();
        } catch (IOException e) {

            e.printStackTrace();
        }finally{
            if(in!=null){
                try {
                    in.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

            if(conn!=null){
                conn.disconnect();
            }

            if(out!=null){
                try {
                    out.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

        }
        return "kong";
    }
}

天气部分的xml

界面上关于天气的代码

    private TextView tianqi;
    private TextView weather_text;
    private TextView air_text;
    private ImageView pic_7;

 air_text=findViewById(R.id.air_text);
        tianqi=findViewById(R.id.textView);
        pic_7=findViewById(R.id.pic_7);
           weather_text = (TextView) findViewById(R.id.wether_text);
        two();
         showDateInfo();

 private void weather() {
        new Thread(  ){
            String a;
            String b;
            @Override
            public void run(){
                a= HttpConnection.getHttpRequest("https://devapi.qweather.com/v7/weather/now?location=101044000&key=你申请的key");
                b= HttpConnection.getHttpRequest("https://devapi.qweather.com/v7/air/now?location=101044000&key=你申请的key");
             runOnUiThread(new Runnable( ) {
                 @Override
                 public void run() {
                     JSonObject jsonObject = JSON.parseObject(a);
                     JSonObject jsonObject1 = JSON.parseObject(b);
                     tianqi.setText((String) jsonObject.getJSONObject("now").get("text"));
                     air_text.setText(" 空气质量"+(String) jsonObject1.getJSONObject("now").get("aqi"));
                     weather_text.setText((String) jsonObject.getJSONObject("now").get("temp")+" ℃");

                 }
             });
            }
        }.start();
