android - java.io.IOException : Is a directory Android 异常

我正在尝试将可绘制文件夹中的图像插入到自定义 ListView 上的 ImageView。但是当我将图像设置为满足条件时，它会从 getView 发出以下警告。

我正在使用扩展 SimpleAdapter 并根据条件放置文本和图标的自定义适配器。

我的客户适配器看起来像..

serviceAdapter = new CustomAdapter(this, serviceList, R.layout.list_row,
                new String[] { "name", "duration","reason", "remark", "img1", "img2", "img3",
                        "img" }, new int[] { R.id.servicename, R.id.duration,R.id.reason, R.id.remark,
                        R.id.statusImg1, R.id.statusImg2, R.id.statusImg3, R.id.isExpandable });

我正在从 HashMap 中放入相应的值...

HashMap<String, Object> rowValue = new HashMap<String, Object>();

和图像使用。 rowValue.put("img2", R.drawable.img);

它不会抛出任何错误，但会大大降低应用程序的速度。任何人都可以让我知道问题可能是什么......

Answer 1

检查图像路径中的图像名称。问题可能出在图像路径中。我确定它指向任何不归档的目录。
