以下是代码，我是从开源修改的，下面是logcat显示错误我检查了很多次代码，但不知道是什么问题。请帮忙。
<?php
if(isset($_POST["login"])){
$error = validate($_POST);
if(empty($error) {
.....//your further processing code
}else{
// code to show your error at appropriate place.
}
}
function validate($dataArray){
$validateArray = $dataArray; // either asign to a new variable or you can use directly $dataArray
$errors = array();
if(empty($_POST['user']) or !preg_match("/^[a-zA-Z0-9 ]*$/", $_POST['user'])){
$errors['user'] = "You can't leave a field empty and you can only use letters, numbers and space.";
}
if(empty($_POST['pass']) or !preg_match("/^[a-zA-Z0-9 ]*$/", $_POST['pass'])){
$errors['pass'] = "You can't leave a field empty and you can only use letters, numbers and space.";
}
//......so on
return $errors;
}
?>
以下是Logcat显示错误。

这是getIconsSet方法
private static final int[][] icons_set = { tiles_fruits, tiles_foods };
完整代码在这里
答案 0 :(得分：1)
你得到java.lang.ArrayIndexOutOfBoundsException: length=2; index=3
因为int set = PreferencesService.instance().getIconsSet();返回3，你的数组icons_set只有两个参数。
确保数组中有足够的元素。

通过添加另一个Icons_set解决了问题。 bcoz有2个索引为0和1，这导致其他方法出现问题。
