Android loopj Async Http 在 1.4.5 更新后崩溃

asynchronous android httprequest java loopj

Android loopj Async Http lib 的新更新已经发布，它们发生了很大变化。现在您需要手动设置，否则默认情况下它使用同步模式而不是异步。我没有得到我需要设置它的地方。Looper.prepare()

07-09 08:16:18.775: W/AsyncHttpResponseHandler(6606): Current thread has not called Looper.prepare(). Forcing synchronous mode.

该消息后，它完全崩溃

我的 Http 请求类：

import android.os.Looper;

import com.loopj.android.http.AsyncHttpClient;
import com.loopj.android.http.AsyncHttpResponseHandler;
import com.loopj.android.http.PersistentCookieStore;
import com.loopj.android.http.RequestParams;

public class HttpRequest {
      public static AsyncHttpClient client = new AsyncHttpClient();

      public static void setCookieStore(PersistentCookieStore cookieStore) {
            client.setCookieStore(cookieStore);
        }

      public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
          Looper.prepare();
          client.get(url, params, responseHandler);
      }

      public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
          Looper.prepare();
          client.post(url, params, responseHandler);
      }
}

任何人都可以帮我吗？

答案 1

我遇到了类似的问题，发现在线程中使用AsyncHttpClient发出HTTP请求导致了这个问题。

我在线程外部运行了我的HTTP请求，它为我解决了这个问题。您可以尝试以下方法：

public class HttpRequest {

  // A SyncHttpClient is an AsyncHttpClient
  public static AsyncHttpClient syncHttpClient= new SyncHttpClient();
  public static AsyncHttpClient asyncHttpClient = new AsyncHttpClient();

  public static void setCookieStore(PersistentCookieStore cookieStore) {
      getClient().setCookieStore(cookieStore);
  }

  public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      getClient().get(url, params, responseHandler);
  }

  public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      getClient().post(url, params, responseHandler);
  }

  /**
   * @return an async client when calling from the main thread, otherwise a sync client.
   */
  private static AsyncHttpClient getClient()
  {
      // Return the synchronous HTTP client when the thread is not prepared
      if (Looper.myLooper() == null)
          return syncHttpClient;
      return asyncHttpClient;
  }
}

我不同意按照保罗的方式去做。虽然我真的看不出一个好方法来解决这个问题，因为我即将呈现的方式也相当笨拙，但是不要使用AsyncHttpResponseHandler，而是使用这个类。

public abstract class AlwaysAsyncHttpResponseHandler extends AsyncHttpResponseHandler {
    @Override
    public boolean getUseSynchronousMode() {
        return false;
    }
}
