我正在尝试在ListView上设置一个Image并且我已经编写了适配器代码，它似乎工作正常，但实际获取图像的行总是给出一个关于无法找到的错误一个图像。
获取图像的代码如下，
Bitmap logo = BitmapFactory.decodeResource(MainActivity.this.getResources(), R.drawable.dm);
// creating new HashMap
HashMap<String, Object> map = new HashMap<String, Object>();
// adding each child node to HashMap key => value
map.put(TAG_BODY, id);
map.put(TAG_TITLE, name);
map.put(TAG_URL, uri);
map.put(TAG_TIME, dateFormated);
map.put(TAG_SITE, logo);
// adding HashList to ArrayList
productsList.add(map);
然后应用于ListView的代码是
ListAdapter adapter;
adapter = new SimpleAdapter(
MainActivity.this, productsList,
R.layout.list_row, new String[] { TAG_BODY, TAG_TITLE, TAG_URL, TAG_TIME, TAG_SITE},
new int[] { R.id.id, R.id.headline, R.id.url, R.id.time, R.id.list_i});
// updating listview
setListAdapter(adapter);
，错误是

答案 0 :(得分：1)
你可以在这里看到android.widget.SimpleAdapter SimpleAdapter的setViewImage方法只接受两个参数：
第一个参数： 要在其中设置当前图像的ImageView ID
第二个参数： 字符串（如果要从文件路径设置ImageView src）或整数（如果要从drawable的id设置ImageView src）
所以你需要只传递drawable id而不是drawable
的Bitmap
