取消进度对话框取消时,取消AsyncHttpClient请求

问题描述 投票:0回答:3

我正在从我的android应用向服务器发出请求,并且我正在使用loopj的AsyncHttpClient库。如果进度对话框被取消(按返回键),我试图取消一个请求,但是实际上发生的是,ProgressDialog被取消了,但是请求继续在后台运行,完成后将我带到另一个活动(这很好,因为这是在取消进度对话框时我想要的行为)。

这是我的代码的一部分,在其中设置了ProgressDialog的setOnCancelListener :(客户端是AsyncHttpClient的实例)

public static void login(final String email, final String password,
            final Context context, final Context appContext, final Resources res) {

        prgDialog = new ProgressDialog(context);
        prgDialog.setMessage(res.getString(R.string.dialog_please_wait));
        prgDialog.setCancelable(true);
        prgDialog.show();
        prgDialog.setOnCancelListener(new OnCancelListener() {

            @Override
            public void onCancel(DialogInterface dialog) {
                client.cancelRequests(context, true);
            }
        });

        cookieStore = new PersistentCookieStore(appContext);
        client.setCookieStore(cookieStore);

        RequestParams params = new RequestParams();
        params.put("user_session[email]", email);
        params.put("user_session[password]", password);

        client.addHeader("Accept", HEADER);

        client.post(getAbsoluteUrl(LOGIN_PATH), params,
                new JsonHttpResponseHandler() {

                    @Override
                    public void onFailure(int statusCode,
                            org.apache.http.Header[] headers,
                            java.lang.String responseString,
                            java.lang.Throwable throwable) {
                        prgDialog.hide();
                        if (statusCode == 404) {
                            Toast.makeText(context,
                                    res.getString(R.string.error_404),
                                    Toast.LENGTH_LONG).show();
                        } else if (statusCode == 500) {
                            Toast.makeText(context,
                                    res.getString(R.string.error_500),
                                    Toast.LENGTH_LONG).show();
                        } else if (statusCode == 401) {
                            Toast.makeText(context,
                                    res.getString(R.string.login_401),
                                    Toast.LENGTH_LONG).show();
                        } else {
                            Toast.makeText(
                                    context,
                                    "Unexpected Error occcured! [Most common Error: Device might not be connected to Internet or remote server is not up and running]",
                                    Toast.LENGTH_LONG).show();
                        }
                    }

                    @Override
                    public void onSuccess(int statusCode, Header[] headers,
                            JSONObject response) {
                        if (statusCode == 200) {
                //do something
                    }
                });
    }

client.post(context,getAbsoluteUrl(LOGIN_PATH), params,
            new JsonHttpResponseHandler();

尝试将方法更改为:

client.cancelAllRequests(true);

client.post(context, apiName, stringEntity, "text/plain",
                    uploadResponseHandler(callBack, apiNumber, requestId, context, resultClass)).setTag("uploadFile");

然后是>>

    client.cancelRequestsByTAG("uploadFile",true);
