我想從可繪製文件夾插入圖像到自定義列表視圖上的ImageView。但是當我設置滿足條件的圖像時，它從getView提供以下警告。java.io.IOException：是一個目錄Android

我正在使用擴展SimpleAdapter並根據條件放置文本和圖標的自定義適配器。
我custome適配器看起來像..
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 });
我從一個HashMap把相應的值...
HashMap<String, Object> rowValue = new HashMap<String, Object>();
並使用圖像。 rowValue.put("img2", R.drawable.img);
它沒有拋出任何錯誤，但放緩了應用程序很多。任何一個可以讓我知道這個問題可能是什麼？
那麼，人們告訴你，你指向一個文件夾，而不是一個文件。確實如此。但你也知道android不能管理可繪製文件夾中的文件夾，你不知道嗎？也就是說，所有的圖像都應該放在drawable的根部。你不能drawable/myfolder/myimage.png。至少還沒有。這只是對你的警告。 – 2011-12-27 07:20:09
我有可繪製的，drawable-hdpi，drawable-mdpi，drawable-ldpi和drawable-xhdpi文件夾，其中放置了相應的圖像。在這裏做錯什麼？ – 2011-12-27 07:31:44
哦，不，這是對的，我的意思是你不能在這些文件夾裏面有文件夾。 – 2011-12-27 14:52:55
