我创建了一个从googlebooksapi读取数据并在recyclerview中显示的应用程序。
有时回收视图中的项目不会显示。
在我的日志中，我得到以下信息（这不是导致我的应用程序崩溃的错误，但它显示了这一点）：

V/AsyncHttpRH: Progress 538 from 1 (53800%)
W/JsonHttpRH: onFailure(int, Header[], Throwable, JSONObject) was not overriden, but callback was received
    cz.msebera.android.httpclient.client.HttpResponseException: Too Many Requests

        at java.lang.Thread.run(Thread.java:764)

什么会导致这个错误？
我使用它的方式是：

MyBookClient.getInstance().getBooks( discoverBooks.getBookID(), new JsonHttpResponseHandler() {
            @Override
            public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
                if (response != null) {
                    final MyBook books = MyBook.fromJson( response );
                }
            }
        } );

哪里：
公共类mybookclient{

private static final String API_BASE_URL = "https://www.googleapis.com/books/v1/volumes/";
private AsyncHttpClient client;

public static MyBookClient instance = new MyBookClient();

public MyBookClient() {
    this.client = new AsyncHttpClient();
}

public static MyBookClient getInstance() {
    return instance;
}

public void getBooks(final String query, JsonHttpResponseHandler handler) {
    try {
        client.get( API_BASE_URL + URLEncoder.encode( query, "utf-8" ), handler );
    } catch (UnsupportedEncodingException ignored) {

    }
}

}
谢谢您！
