嘿伙计们我正在构建一个应用程序，我想从url的一些图像进入listview内的android imageview。我使用了aquery库，我收到了这个错误
04-09 17:56:43.864: I/System.out(1580): resolveUri failed on bad bitmap uri:
04-09 17:56:43.894: E/BitmapFactory(1580): Unable to decode stream: java.io.FileNotFoundException: /: open failed: EISDIR (Is a directory)
我实际上并不知道这怎么可能更容易。
我的代码是：
public class JsonReadTask extends AsyncTask<String, Void, String> {
public JsonReadTask(){
super();
}
@SuppressLint("InlinedApi")
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(MainActivity.this, ProgressDialog.THEME_DEVICE_DEFAULT_DARK);
pDialog.setTitle(R.string.waiting);
pDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pDialog.setMessage(getString(R.string.get_stocks));
pDialog.setIndeterminate(true);
pDialog.setCancelable(false);
pDialog.setInverseBackgroundForced(true);
pDialog.show();
}
@Override
protected String doInBackground(String... params) {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(params[0]);
try {
HttpResponse response = httpclient.execute(httppost);
jsonResult = inputStreamToString(
response.getEntity().getContent()).toString();
}
catch (Exception e) {
Intent intent1 = new Intent(MainActivity.this, RefreshActivity.class);
startActivityForResult(intent1, 0);
}
return null;
}
private StringBuilder inputStreamToString(InputStream is) {
String rLine = "";
StringBuilder answer = new StringBuilder();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
try {
while ((rLine = rd.readLine()) != null) {
answer.append(rLine);
}
}
catch (Exception e) {
Intent intent1 = new Intent(MainActivity.this, RefreshActivity.class);
startActivity(intent1);
startActivityForResult(intent1, 0);
}
return answer;
}
@Override
protected void onPostExecute(String result) {
ListDrawer();
pDialog.dismiss();
}
}// end async task
public void accessWebService() {
JsonReadTask task = new JsonReadTask();
// passes values for the urls string array
task.execute(new String[] { url });
}

有人能指出我正确加载图片的方法吗？
提前致谢!!
