我尝试处理哈希图以显示带有图像的列表视图。我在这里搜索答案:如何在 ListView android 中显示图像。但它不起作用...
我的代码是:
for (int i = 0; i < nodes.getLength(); i++) {
Element e = (Element)nodes.item(i);
Map<String, Object> datum = new HashMap<String, Object>(2);
String img_url = getValue(e, "pic");
URL url = null;
try {
url = new URL(img_url);
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Bitmap bmp = null;
try {
bmp=BitmapFactory.decodeStream(url.openConnection().getInputStream());
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
datum.put("imgurl", bmp);
datum.put("title", getValue(e, "title"));
datum.put("date", getValue(e, "description"));
datum.put("ex", "Autor: "+getValue(e, "creator")+" · Datum: "+getValue(e, "pubDate"));
datum.put("id", getValue(e, "id"));
data.add(datum);
}
final ListView lv = (ListView)findViewById(R.id.listView1);
ada = new SimpleAdapter(getApplicationContext(), data, R.layout.vlistimage, new String[] {"imgurl", "title", "date", "ex", "id"}, new int[] {R.id.list_image, android.R.id.text1, android.R.id.text2, R.id.text3});
lv.setAdapter(ada);
感谢您的提示/帮助!
