在我的應用程序中,我從服務器上獲取圖像和數據。當互聯網連接有圖像加載正確。當互聯網連接速度減慢時,應用程序會繼續運行,並在某段時間後突然停止。應用程序停止一段時間後下載圖像緩慢連接
這是AsyncTask
從服務器獲取的圖像和數據:
public void getPendingList() {
new AsyncTask<Void, Void, String>() {
protected void onPreExecute() {
progressDialog = new ProgressDialog(getActivity());
progressDialog.setTitle("Loading....");
progressDialog.setMessage("Please Wait...");
progressDialog.setCancelable(true);
progressDialog.show();
}
protected String doInBackground(Void... params) {
prepareList();
getRegistrationDetails();
getStateList();
for (int i = 0; i < districts.size(); i++) {
JSONObject jsonObject;
try {
jsonObject = new JSONObject(districts.get(i));
String val1 = jsonObject.getString("OptionalParameter");
int val2 = jsonObject.getInt("ItemID");
String val3 = jsonObject.getString("Item_Description");
double val4 = jsonObject.getDouble("Item_Price");
String val5 = jsonObject.getString("Item_Code");
String val6 = jsonObject.getString("Item_Name");
String val7 = jsonObject.getString("ImageFinal");
String ItemCode = jsonObject.getString("Item_Code");
val7.replace("/", "");
listmodel.add(new Item_Master(val2, val3, val4, val6, val7, ItemCode));
listCountry.add("\u20B9" + val4);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return "response";
}
protected void onPostExecute(String result) {
if (result != null) {
if (!result.equals("NO_NETWORK")) {
mAdapter = new GridviewAdapter_Item_Master(FaramentView.getContext(), listmodel);
gridview.setAdapter(mAdapter);
}
dismissDialog();
}
}.execute(null, null);
}
}
得到這個數據後,我在設定這個數據GridView
適配器和圖像設置。我使用畢加索圖書館下載圖像並設置以下代碼:
Picasso.with(context).load(list.get(position).getImagePath()).centerCrop()
.resize(150, 150).error(R.drawable.ic_launcher).into(view.imgViewFlag);
如何在緩慢的互聯網連接中加載圖像?

讓我知道如果適合和案例投票了,請 – 2014-09-19 12:53:01
