Android HTTPGET返回的Json帮助

嘿，伙计们，我需要关于提取JSON值的帮助。我试着解析，但结果没有出来

以下是我的java代码：

public class MyAct extends Activity {

    EditText etResponse;
    TextView tvIsConnected;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.result);
        String s = getIntent().getStringExtra("username");

        // get reference to the views
        etResponse = (EditText) findViewById(R.id.etResponse);
        tvIsConnected = (TextView) findViewById(R.id.tvIsConnected);

        // check if you are connected or not
        if(isConnected()){
            tvIsConnected.setBackgroundColor(0xFF00CC00);
            tvIsConnected.setText("You are connected");
        }
        else{
            tvIsConnected.setText("You are NOT conncted");
        }

        // show response on the EditText etResponse
        //etResponse.setText(GET("http://hmkcode.com/examples/index.php"));

        // call AsynTask to perform network operation on separate thread

        new HttpAsyncTask().execute("https://api.github.com/users/" + s + "/repos" );
    }

    public static String GET(String url){
        InputStream inputStream = null;
        String result = "";
        String dat = "";

        try {

            // create HttpClient
            HttpClient httpclient = new DefaultHttpClient();

            // make GET request to the given URL
            HttpResponse httpResponse = httpclient.execute(new HttpGet(url));

            // receive response as inputStream
            inputStream = httpResponse.getEntity().getContent();

            // convert inputstream to string
            if(inputStream != null) {
               result = convertInputStreamToString(inputStream);
               dat = result;
            }
            else
                result = "Did not work!";

        } catch (Exception e) {
            Log.d("InputStream", e.getLocalizedMessage());
        }

        return result;
    }

    private static String convertInputStreamToString(InputStream inputStream) throws IOException{
        BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream));
        String line = "";
        String result = "";
        while((line = bufferedReader.readLine()) != null)
            result += line;

        inputStream.close();
        return result;

    }

    public boolean isConnected(){
        ConnectivityManager connMgr = (ConnectivityManager) getSystemService(this.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
        if (networkInfo != null && networkInfo.isConnected())
            return true;
        else
            return false;
    }

    private class HttpAsyncTask extends AsyncTask<String, Void, String> {
        @Override
        protected String doInBackground(String... urls) {

            return GET(urls[0]);
        }
        // onPostExecute displays the results of the AsyncTask.
        @Override
        protected void onPostExecute(String result) {
            Toast.makeText(getBaseContext(), "Received!", Toast.LENGTH_LONG).show();
            etResponse.setText(result);
        }
    }

}

现在我想从中提取像

HTML\uurl

和forks等项目。这是

JSON

。

帮帮我，伙计们。

有些疑问。在哪里指定要提取的字段。如何打印输出？在onPostExecute（）中，对不起，我是初学者，我应该在设置的文本中输入Wat值。我如何指定我想要的字段，比如“id”、“forks\u count”等。首先参考链接来解析json

private class HttpAsyncTask extends AsyncTask<String, Void, Object> {
        @Override
        protected Object doInBackground(String... urls) {
           JSONParser jParser = new JSONParser();   
           Object object = jParser.getJsonObject(urls[0]);
            return object;
        }
        // onPostExecute displays the results of the AsyncTask.
            @Override
        public void onPostExecute(Object result){
        JSONObject jsonObject = (JSONObject) result;
        JSONArray jsonArray = jsonObject.getJSONArray("data");
        for(int i=0;i<jsonArray.length;i++){
        System.out.println(jsObject.getString("id"));

        }
        System.out.println(jsObject.getString("forks_count"));
        }

    }

private class HttpAsyncTask extends AsyncTask<String, Void, Object> {
        @Override
        protected Object doInBackground(String... urls) {
           JSONParser jParser = new JSONParser();   
           Object object = jParser.getJsonObject(urls[0]);
            return object;
        }
        // onPostExecute displays the results of the AsyncTask.
            @Override
        public void onPostExecute(Object result){
        JSONObject jsonObject = (JSONObject) result;
        JSONArray jsonArray = jsonObject.getJSONArray("data");
        for(int i=0;i<jsonArray.length;i++){
        System.out.println(jsObject.getString("id"));

        }
        System.out.println(jsObject.getString("forks_count"));
        }

    }

 public class JSONParser {
      static InputStream is = null;
                static JSONObject jObj = null;
                static String json = "";

                public JSONParser() {
                }

                /**

                        if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
                            HttpEntity httpEntity = httpResponse.getEntity();
                            json = EntityUtils.toString(httpEntity);
                            try {
