android - 从 json 加载数千个值

Question

我想点击一个 api，我将在其中获得很多值并希望在 ListView 中显示。

在 listview 上显示数据我可以做到，但问题是我无法在我的 android 应用程序中加载完整数据。当我点击 api 作为响应时，我得到的数据很少，或者只能说只有几行，但数据有数千行。

当我从网络浏览器点击 api 时，它会显示所有数据，但是当我在我的 android 应用程序上使用它时，点击按钮只会提供有限的数据。

提前致谢:)

获取按钮点击数据的代码

try {
                 String url = "my url";

             HttpHandler sh = new HttpHandler();

                // Making a request to url and getting response
                String jsonStr = sh.makeServiceCall(url);


                Log.e("Response from url:", "" + jsonStr);

        }

HttpHandler类代码

public class HttpHandler {

private static final String TAG = HttpHandler.class.getSimpleName();

public HttpHandler() {
}

public String makeServiceCall(String reqUrl) {
    String response = null;
    try {
        URL url = new URL(reqUrl);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("POST");
        // read the response
        InputStream in = new BufferedInputStream(conn.getInputStream());
        response = convertStreamToString(in);
    } catch (MalformedURLException e) {
        Log.e(TAG, "MalformedURLException: " + e.getMessage());
    } catch (ProtocolException e) {
        Log.e(TAG, "ProtocolException: " + e.getMessage());
    } catch (IOException e) {
        Log.e(TAG, "IOException: " + e.getMessage());
    } catch (Exception e) {
        Log.e(TAG, "Exception: " + e.getMessage());
    }
    return response;
}

private String convertStreamToString(InputStream is) {
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();

    String line;
    try {
        while ((line = reader.readLine()) != null) {
            sb.append(line).append('\n');
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return sb.toString();
}

似乎是调试器问题切断了太长的消息
