Android studio 错误：应为BEGIN\u数组，但为BEGIN\u对象

进程：com.example.venky.httpurl1，PID:2578 java.lang.RuntimeException:com.google.gson.JsonSyntaxException:java.lang.IllegalStateException:应为BEGIN_数组，但在第1行第3列路径$[0]处为BEGIN_对象

有什么意见吗？？

这是因为我的JSON数据吗？？？

在将其转换为字符串并将其解析为

JSON

值之前，请检查

responseBody

是否为

NULL

或空

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) {
            if(responseBody != null && responseBody.length > 0) {
                String responsestr = new String(responseBody);
                gson = new Gson();
                responseObj = gson.fromJson(responsestr, Response.class);
                adapter = new CustomAdapter(MainActivity.this, responseObj);
                listView.setAdapter(adapter);
            }
        }
