[0049] 参照图 1, 提出本发明的操作响应方法第一实施例, 所述操作响应方法包括以 下步骤:
[0050] Sl l、 检测本次操作拟访问的数组是否为空。 当数组为空吋, 进入步骤 S12; 当 数组不为空吋, 进入步骤 S13。
[0051] S12、 不予响应本次操作。
[0052] S13、 响应本次操作。
[0053] 步骤 S11中, 当用户对车载系统进行操作吋, 车载系统根据用户的操作确定本 次操作拟访问的数组, 并检测该数组是否为空。 具体的, 车载系统读取数组的 大小, 判断数组的大小是否小于或等于阈值; 当数组的大小小于或等于阈值吋
, 判断数组为空; 当数组的大小大于阈值吋, 判定数组不为空。 阈值可以根据 实际需要设定, 例如可以设定为 0-100B。
[0054] 此外, 也可以采用现有技术中的其它方式来检测数组是否为空, 本发明在此不 在一一列举赘述。
[0055] 步骤 S12中, 当检测到数组为空吋, 车载系统则不予响应本次操作, 不访问该 数组, 从而防止访问空指针而出现卡顿、 崩溃、 死机等异常现象, 提高系统稳 定性。
[0056] 步骤 S13中, 当检测到数组不为空吋, 车载系统则响应本次操作, 访问该数组
, 遍历该数组中的每一个元素。
[0057] 进一步地, 当检测到数组为空吋, 车载系统还可以返回提示信息, 所述提示信 息如"本次操作失败, 请重新操作"、 "本次操作异常, 请重新操作"、 "请重新操 作"等, 以使用户得知本次操作异常, 则重新进行操作, 避免用户长吋间等待车 载系统响应而浪费吋间, 提升了用户体验。 [0058] 进一步地, 如图 2所示, 在本发明的操作响应方法第二实施例中, 步骤 S11之前 还包括以下步骤:
[0059] S10、 判断本次操作拟访问的数组是否为访问频繁的数组。 当该数组是访问频 繁的数组吋, 进入下一步骤 S11 ; 当该数组不是访问频繁的数组吋, 直接进入步 骤 S13, 即不对数组是否为空进行检测, 直接响应本次操作, 访问该数组。 当然 , 当该数组不是访问频繁的数组吋, 也可以做其它操作, 本发明对此不作限定
[0060] 可选地, 当拟访问的数组为视图 (view) 数组、 软件包 (packages) 数组、 活 动 (activity) 数组、 进程 (process) 数组或线程 (thread) 数组吋, 则判定该数 组为访问频繁的数组。 当然, 根据实际需要, 也可能其它数组访问频繁, 则将 其它数组认定为访问频繁的数组。
[0061] 考虑到通常访问频繁的数组出现空数组的几率比较大, 因此本实施例只对访问 频繁的数组是否为空进行检测, 以提高响应效率。
[0062] 本发明实施例的操作响应方法, 通过在访问数组之前先检测该数组是否为空, 当数组为空吋则不响应本次操作, 从而防止访问空数组吋出现空指针访问, 避 免了访问空指针导致的卡顿、 崩溃、 死机等异常问题, 提高了系统的稳定性。
[0063] 参照图 3, 提出本发明的操作响应装置第一实施例, 所述装置包括检测模块 10 和处理模块 20, 其中: 检测模块 10, 用于检测本次操作拟访问的数组是否为空 ; 处理模块 20, 用于当本次操作拟访问的数组为空吋, 不予响应本次操作; 当 数组不为空吋, 响应本次操作。
[0064] 本发明实施例中, 当用户对车载系统进行操作吋, 检测模块 10则根据用户的操 作确定本次操作拟访问的数组, 并检测该数组是否为空。
[0065] 可选地, 如图 4所示, 检测模块 10包括读取单元 11、 判断单元 12和判决单元 13 , 其中: 读取单元 11, 用于读取本次操作拟访问的数组的大小; 判断单元 12, 用于判断该数组的大小是否小于或等于阈值; 判决单元 13, 用于当该数组的大 小小于或等于阈值吋, 判定该数组为空; 当该数组的大小大于阈值吋, 判定该 数组不为空。 阈值可以根据实际需要设定, 例如可以设定为 0-100B。
[0066] 此外, 检测模块 10也可以采用现有技术中的其它方式来检测数组是否为空, 本 发明在此不在一一列举赘述。
[0067] 当检测到数组不为空吋, 处理模块 20则响应本次操作, 访问该数组, 遍历该数 组中的每一个元素。 当检测到数组为空吋, 处理模块 20则不予响应本次操作, 不访问该数组, 从而防止访问空指针而出现卡顿、 崩溃、 死机等异常现象, 提 高系统稳定性。
[0068] 进一步地, 如图 5所示, 在本发明的操作响应装置第二实施例中, 该装置还包 括提示模块 30, 其用于: 当数组为空吋, 返回提示信息。 所述提示信息可以是 语音信息、 文字信息和 /或图像信息。
[0069] 所述提示信息如"本次操作失败, 请重新操作"、 "本次操作异常, 请重新操作" 、 "请重新操作 "等, 以使用户得知本次操作异常, 则重新进行操作, 避免用户长 吋间等待车载系统响应而浪费吋间, 提升了用户体验。
[0070] 进一步地, 如图 6所示, 在本发明的操作响应装置第三实施例中, 该装置还包 括判断模块 40, 该判断模块 40用于: 判断本次操作拟访问的数组是否为访问频 繁的数组, 当数组为访问频繁的数组吋, 通知检测模块 10, 以使检测模块 10判 断该数组是否为空。 当数组不是访问频繁的数组吋, 判断模块 40则通知处理模 块 20, 处理模块 20则直接响应本次操作, 直接访问该数组。 当然, 当数组不是 访问频繁的数组吋, 处理模块 20也可以做其它操作, 本发明对此不作限定。
[0071] 可选地, 当拟访问的数组为视图 (view) 数组、 软件包 (packages) 数组、 活 动 (activity) 数组、 进程 (process) 数组或线程 (thread) 数组吋, 判断模块 40 则判定该数组为访问频繁的数组。 当然, 根据实际需要, 也可能其它数组访问 频繁, 判断模块 40则将其它数组认定为访问频繁的数组。
[0072] 考虑到通常访问频繁的数组出现空数组的几率比较大, 因此本实施例只对访问 频繁的数组是否为空进行检测, 以提高响应效率。
[0073] 在某些实施例中, 也可以省略图 6中的提示模块 30, 形成新的实施例。
[0074] 本发明实施例的操作响应装置, 通过在访问数组之前先检测该数组是否为空, 当数组为空吋则不响应本次操作, 从而防止访问空数组吋出现空指针访问, 避 免了访问空指针导致的卡顿、 崩溃、 死机等异常现象, 提高了系统的稳定性。
[0075] 本发明同吋提出一种车载系统, 所述车载系统包括存储器、 处理器和至少一个 被存储在存储器中并被配置为由处理器执行的应用程序, 所述应用程序被配置 为用于执行操作响应方法。 所述操作响应方法包括以下步骤: 检测本次操作拟 访问的数组是否为空; 当数组为空吋, 不予响应本次操作; 当数组不为空吋, 响应本次操作。 本实施例中所描述的操作响应方法为本发明中上述实施例所涉 及的操作响应方法, 在此不再赘述。
[0076] 本发明实施例的车载系统, 通过在访问数组之前先检测该数组是否为空, 当数 组为空吋则不响应本次操作, 从而防止访问空数组吋出现空指针访问, 避免了 访问空指针导致的卡顿、 崩溃、 死机等异常问题, 提高了系统的稳定性。
