這是我的代碼,我試圖將圖像傳遞給列表視圖,但我得到錯誤。 我如何傳遞圖像?我應該先下載到本地內存然後發送它的列表視圖?如何加載圖像並使用JSON數據傳遞給Layout?
protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
// getting JSON string from URL

System.out.println("NULL");
else{
// Check your log cat for JSON reponse
Log.d("All Developers: ", json.toString());
try {
// Checking for SUCCESS TAG
int status = json.getInt(TAG_STATUS);
if (status == 1) {
// products found

developers = json.getJSONArray(TAG_all);
// looping through All Products
