Android 需要列表数组自定义列表适配器中的动态arraylist（位图和2个字符串）

我想让大家都知道如何将1个位图数组和2个字符串数组组合成一个列表数组。位图和字符串数组是根据拍摄的图像量动态创建的。我以前用下面的代码创建过类似的东西，但没有使用动态图像或字符串。由于我对数组不太熟悉，如果有人能帮助我处理细节步骤，那就太好了。非常感谢

我知道它可能需要文本，但不知道如何转换arraylist以将其作为字符串添加到holder中

有什么问题？预期的行为和实际发生的情况是什么？它为adapter-listView.setAdapteradapter；提供了空点异常；。我想要一种方法，使共享首选项中的一个图像和2个字符串显示在数组中。图像和字符串没有确定的数字，数组根据用户选择获取图像。是否为列表使用正确的id？Listview可能为null，因为找不到指定的视图。id正确。我觉得它可能在我的自定义适配器中，但不太确定，因为我有点忘记了数组列表/适配器。放置Log.dTAG，listview为空？+listView==null；。它可能是android.R.id.list。
