错误：预计BEGIN_ARRAY但是BEGIN_OBJECT

Question

  

处理：com.example.venky.httpurl1，PID：2578                                                                             java.lang.RuntimeException：com.google.gson.JsonSyntaxException：java.lang.IllegalStateException：预期为BEGIN_ARRAY，但在第1行第3列路径为BEGIN_OBJECT $ [0]

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    listView = (ListView) findViewById(R.id.rtlist);
    client = new AsyncHttpClient();
    client.get(MainActivity.this, url, new com.loopj.android.http.AsyncHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, cz.msebera.android.httpclient.Header[] headers, byte[] responseBody) {
            String responsestr = new String(responseBody);
            gson = new Gson();
            responseObj = gson.fromJson(responsestr, Response.class);
            adapter = new CustomAdapter(MainActivity.this, responseObj);
            listView.setAdapter(adapter);
        }

任何输入请？ 是因为我的JSON数据吗？
