如何在不使用AsyncTask的情况下在安卓中发送post请求

public class MainActivity extends AppCompatActivity {
    private static final String API_URL = "https://example.com/api";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    URL url = new URL(API_URL);
                    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                    connection.setRequestMethod("POST");
                    connection.setDoOutput(true);

                    // 设置POST请求的参数
                    String postData = "param1=value1&param2=value2";
                    OutputStream outputStream = connection.getOutputStream();
                    outputStream.write(postData.getBytes());
                    outputStream.flush();
                    outputStream.close();

                    // 获取服务器返回的数据
                    int responseCode = connection.getResponseCode();
                    if (responseCode == HttpURLConnection.HTTP_OK) {
                        InputStream inputStream = connection.getInputStream();
                        // 处理输入流中的数据
                        // ...
                        inputStream.close();
                    }

                    connection.disconnect();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }).start();
    }
}
