You're gonna want to get familiar with InputStreams and OutputStreams in Android, if you've done this in regular java before then its essentially the same thing. You need to open a connection with the request property as "GET", you then write your parameters to the output stream and read the response through an input stream. You can see this in my code below:

你会想要熟悉 Android 中的 InputStreams 和 OutputStreams,如果你之前在普通 Java 中做过这件事,那么它本质上是一样的。您需要打开一个请求属性为“GET”的连接,然后将参数写入输出流并通过输入流读取响应。您可以在下面的代码中看到这一点:

        try {
        URL url = null;
        String response = null;
        String parameters = "param1=value1&param2=value2";
        url = new URL("http://www.somedomain.com/sendGetData.php");
        //create the connection
        connection = (HttpURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setRequestProperty("Content-Type",
                "application/x-www-form-urlencoded");
        //set the request method to GET
        connection.setRequestMethod("GET");
        //get the output stream from the connection you created
        request = new OutputStreamWriter(connection.getOutputStream());
        //write your data to the ouputstream
        request.write(parameters);
        request.flush();
        request.close();
        String line = "";
        //create your inputsream
        InputStreamReader isr = new InputStreamReader(
                connection.getInputStream());
        //read in the data from input stream, this can be done a variety of ways
        BufferedReader reader = new BufferedReader(isr);
        StringBuilder sb = new StringBuilder();
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        //get the string version of the response data
        response = sb.toString();
        //do what you want with the data now

        //always remember to close your input and output streams 
        isr.close();
        reader.close();
    } catch (IOException e) {
        Log.e("HTTP GET:", e.toString());
    }
