嘿，我正在构建一个应用程序，我想从URL的一些图像到一个listview里面的android imageview。我用aquery图书馆，我得到这个错误从url加载图像到android listview
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)
我不知道实际上这可能会更容易。
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 });
}
public void ListDrawer() {
stocksList = new ArrayList<HashMap<String, String>>();
androidAQuery = new AQuery(MainActivity.this);
try {
JSONObject jsonResponse = new JSONObject(jsonResult);
JSONArray jsonMainNode = jsonResponse.optJSONArray("metoxes");
for (int i = 0; i < jsonMainNode.length(); i++) {
JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
String name = jsonChildNode.optString("name");
String price = jsonChildNode.optString("price");
String price1 = jsonChildNode.optString("price1");
String price2 = jsonChildNode.optString("price2");

androidAQuery.id(imagelist).image(image, true, true, 72, R.drawable.ic_image_preloaded);
stocksList.add(createStockList(name, price, price1, price2, price3, price4, price5, price6, price7, price8, price9, price10, price11, price12, price13, price14, price15));
}
} catch (Exception e) {

int[] to = { R.id.stock_name, R.id.stock_price, R.id.imagestartinglist};
SimpleAdapter simpleAdapter = new SimpleAdapter(this, stocksList,
R.layout.list_item,

listView.setAdapter(simpleAdapter);
}
public HashMap<String, String> createStockList(String name, String price, String price1, String price2, String price3, String price4, String price5, String price6, String price7, String price8, String price9, String price10, String price11, String price12, String price13, String price14, String price15) {
HashMap<String, String> stockNameNo = new HashMap<String, String>();
stockNameNo.put("name", name);
stockNameNo.put("price", price);
stockNameNo.put("price1", price1);
stockNameNo.put("price2", price2);
stockNameNo.put("price3", price3);
stockNameNo.put("price4", price4);
stockNameNo.put("price5", price5);
stockNameNo.put("price6", price6);
stockNameNo.put("price7", price7);
stockNameNo.put("price8", price8);
stockNameNo.put("price9", price9);
stockNameNo.put("price10", price10);
stockNameNo.put("price11", price11);
stockNameNo.put("price12", price12);
stockNameNo.put("price13", price13);
stockNameNo.put("price14", price14);
stockNameNo.put("price15", price15);
//stockNameNo.put("image", image);
return stockNameNo;
}
}
可能有人点我到正确加载图像的方式？
在此先感谢！
