尝尝这个

  String myjsonstring = "http://52.206.14.188:8080/Configuration";


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


    try
    {
        JSONArray jsonArray = new JSONArray(myjsonstring);

        for (int i = 0; i < jsonArray.length(); i++) {

            JSONObject currentobject = jsonArray.getJSONObject(i);
            String configurationId = currentobject.getString("configurationId");
            String configurationName = currentobject.getString("configurationName");
            String configurationVal = currentobject.getString("configurationVal");

            Log.i("configurationId", ":" + configurationId);
            Log.i("configurationName", ":" + configurationName);
            Log.i("configurationVal", ":" + configurationVal);

            TextView tv = (TextView)findViewById(R.id.tv);
            tv.setText(configurationId);
            tv.setText(configurationName);
            tv.setText(configurationVal);


        }


    }
    catch (JSONException e)
    {
        e.printStackTrace();
    }
}

}
