私はそのようなことを試しました

 String data = EntityUtils.toString(response.getEntity());


           JSONObject jsonObj = new JSONObject(data);
           Object jj=jsonObj.getJSONObject("results").get("name");

しかし、私は JSONEXCEPTION を得ました

結果はオブジェクトではなく配列です。

JSONObject jsonObj = new JSONObject(data);    
JSONArray results =jsonObj.getJSONArray("results");

for (int i = 0; i < results.length(); i++) {
  JSONObject result = results.getJSONObject(i);

  String name = result.getString("name");
  Log.d("tag", "name: " + name)
}

ここにはコンパイラがないため、構文をチェックできません。
