如何在Android中从URL获取数据？

<uses-permission android:name="android.permission.INTERNET" />

URL url = new URL("http://example.com/data"); // 替换为要获取数据的URL
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");

// 可选：如果需要在请求中添加参数，可以使用以下代码
// connection.setDoOutput(true);
// OutputStream outputStream = connection.getOutputStream();
// outputStream.write(parameters.getBytes());
// outputStream.flush();
// outputStream.close();

int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
    InputStream inputStream = connection.getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
    StringBuilder response = new StringBuilder();
    String line;
    while ((line = reader.readLine()) != null) {
        response.append(line);
    }
    reader.close();
    String responseData = response.toString();
    // 在这里处理获取到的数据
} else {
    // 请求失败，处理错误情况
}

connection.disconnect();
