嗨,我在PHP Excel中创建多个工作表,但它无法正常工作.我面临一个问题"你试图通过越界索引设置一张活动表:1.实际页数是1."

这是我的代码:

function downloadReportInExcel($excelSheetDetails, $headers, $resultSetFields, $resultSetPointer) {
    /** Error reporting */
    error_reporting(E_ALL);
    ini_set('display_errors', TRUE);
    ini_set('display_startup_errors', TRUE);
    date_default_timezone_set('Asia/Calcutta');

    if (PHP_SAPI == 'cli')
        die('This example should only be run from a Web Browser');

    /** Include PHPExcel */
    require_once '../../lib/PHPExcel.php';


    // Create new PHPExcel object
    $objPHPExcel = new PHPExcel();

    //Enable cell caching and serialize it so that memory footprint is small and performance is high
    $cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_in_memory_serialized;
    PHPExcel_Settings::setCacheStorageMethod($cacheMethod);

    //Setting a default height for all rows
    $objPHPExcel->getActiveSheet()->getDefaultRowDimension()->setRowHeight(15);

    // Set document properties …

我是android和volley 的新手。我创建了一个登录程序来从我的服务器获取json数据，但它不起作用。单击登录按钮后不显示json 响应。我在下面粘贴我的代码。

package com.volley.cuser.volleyexample;

import org.json.JSONException;
import org.json.JSONObject;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;

import com.android.volley.NetworkResponse;
import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.JsonObjectRequest;
import com.android.volley.toolbox.Volley;

public class MainActivity extends Activity {

    private TextView txtDisplay;
    EditText editText;
    EditText editText2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        editText = (EditText) findViewById(R.id.username);
        editText2 = (EditText) findViewById(R.id.password);
    } …
