GridView doesn't show anything after JSON parsing the values into its items

I have gridview for a tab in tabLayout. I load the values from mysql database to fill the textviews of gridview. I see that the JSON parsing runs correctly and returns correct JSON result. But nothing shows up in grid view.

I have tried searching on Google and stackoverflow , found nothing successful,

`
Storenamefinal will have entries of storenames from resulting JSON(above)

I tried your code and it crashes the application
after debugging i got that the problem is with the image resources
when i commented below two lines the app works fine.
//check these resources
Integer x=imagelinks.get(position);
imageViewStoreImage.setImageResource(x);
your showJSON() function that i tried
private void showJSON() {
try {
String response ="{\"result\":[{\"storename\":\"Flipkart.com\",\"imagelinks\":\"\",\"mainpriority\":\"2\"},{\"storename\":\"Jabong.com\",\"imagelinks\":\"\",\"mainpriority\":\"4\"},{\"storename\":\"Myntra.com\",\"imagelinks\":\"\",\"mainpriority\":\"5\"},{\"storename\":\"Amazon.in\",\"imagelinks\":\"\",\"mainpriority\":\"1\"},{\"storename\":\"Snapdeal.com\",\"imagelinks\":\"\",\"mainpriority\":\"3\"},{\"storename\":\"Koovs.in\",\"imagelinks\":\"\",\"mainpriority\":\"6\"},{\"storename\":\"Limeroad.com\",\"imagelinks\":\"\",\"mainpriority\":\"7\"},{\"storename\":\"Shopperstop.com\",\"imagelinks\":\"\",\"mainpriority\":\"8\"},{\"storename\":\"Stalkbuylove.com\",\"imagelinks\":\"\",\"mainpriority\":\"9\"},{\"storename\":\"Yepme.com\",\"imagelinks\":\"\",\"mainpriority\":\"10\"},{\"storename\":\"Faballey.com\",\"imagelinks\":\"\",\"mainpriority\":\"11\"},{\"storename\":\"Fabindia.com \",\"imagelinks\":\"\",\"mainpriority\":\"12\"},{\"storename\":\"PrettySecrets.com\",\"imagelinks\":\"\",\"mainpriority\":\"13\"},{\"storename\":\"AmericanSwan.com\",\"imagelinks\":\"\",\"mainpriority\":\"14\"},{\"storename\":\"Clovia.com\",\"imagelinks\":\"\",\"mainpriority\":\"15\"},{\"storename\":\"Bata.in\",\"imagelinks\":\"\",\"mainpriority\":\"16\"},{\"storename\":\"TrendyBharat.com\",\"imagelinks\":\"\",\"mainpriority\":\"17\"},{\"storename\":\"Royzez.com\",\"imagelinks\":\"\",\"mainpriority\":\"18\"}]} ";

You can try this,
Change your code
if(results.size() > 0){
SearchAdapter searchAdapter = new SearchAdapter(SearchActivity.this);
searchAdapter.setData(results);
mListViewSearchUsers.setAdapter(searchAdapter);
textNotFound.setVisibility(View.GONE);
}else {
textNotFound.setVisibility(View.VISIBLE);
textNotFound.setText("No users found");
}
to
if(results.size() > 0){
SearchAdapter searchAdapter = new SearchAdapter(SearchActivity.this);
if (searchAdapter== null) {
searchAdapter.setData(results);
mListViewSearchUsers.setAdapter(searchAdapter);
} else {
searchAdapter.setData(results);
mListViewSearchUsers.notifyDatasetChange();
}
textNotFound.setVisibility(View.GONE);
}else {
textNotFound.setVisibility(View.VISIBLE);
textNotFound.setText("No users found");
}
Change some code in adapter (comment some code)
public void setData(List<User> data) {
// clear();
if (data != null) {
addAll(data);
// notifyDataSetChanged();
}
}
Update:(problem resolved by comm‌​ents this line)
mListViewTimeline.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
I hope this will help you.

Search Function didn't work

appreciate your help here. I don't why it didn't work. I have added the following function to search for user. I debug it and it appears it stucked at the filter (argo) function. My code as follows. There is nothing in the logcat error. Appreciate your help.

I have similar code that can be useful:
In this code , we have several class:
First:Search class that search in a list and show result in list view
Second: CustomAdapter that prepare list view
Third: Main that call Search function in Search class
public class Search
{
android.content.Context context;
CustomAdaptor tempAdptr;
CustomAdaptor adptr;
android.widget.ListView lstContact;
java.util.ArrayList<MyObject> arrMyObject;
public SearchContact(android.content.Context con , CustomAdaptor adp , android.widget.ListView lst )
{
context = con;
arrMyObject = new java.util.ArrayList<MyObject>();
tempAdptr = new CustomAdaptor(context, R.layout.contact_row, arrMyObject);
adptr = adp;
lstContact = lst;
}
public void Search(String strSearch)
{
lstContact.setAdapter(tempAdptr);
if(strSearch.equals(""))
{
lstContact.setAdapter(adptr);
return ;
}
arrMyObject.removeAll(arrMyObject) ;
for(int i = 0 ; i < MainActivity.GetArrMyObject().size() ; i++)
{
if(arrlist.get(i).contains(strSearch))
{
//Add item to your list
}
}
tempAdptr.notifyDataSetChanged();
}
}
//------------------------------------------------------------------------------------
public class CustomAdaptor extends ArrayAdapter<MyObject> {
android.content.Context context;
int resId;
java.util.ArrayList<MyObject> arrData;
public ContactAdaptor(android.content.Context ac, int resource , java.util.ArrayList<MyObject> data ) {
super(ac, resource, data);
context = ac;
resId = resource;
arrData = data;
}
#Override
public android.view.View getView(final int position,android.view.View convertView, android.view.ViewGroup parent)
{
try
{
MyObject member = arrData.get(position);
android.view.LayoutInflater inflater = (LayoutInflater) context.getSystemService(android.content.Context.LAYOUT_INFLATER_SERVICE);
android.view.View Row =inflater.inflate(resId, parent , false);
// Set Your XML file
return Row;
}
catch (Exception e)
{
return null;
}
}
}
Now you can use this code in main:
SearchContact srchContact = new SearchContact(context, adptr, arraylist);
srchContact.Search(YourObject);

How do i pass the value of my username and its id to the next activity?

I want to be able to click on the "username" which will lead me to a new class - SetMed.java. Along with the username, i would like it's ID's to be passed on as well. I have tried using Intent but it does not work. Any help is greatly appreciated.

map.put("friend_image", R.drawable.icon);
map.put("friend_username", name[i]);
map.put("friend_id", id[i]);
map.put("selected", false);
//Add data
listData.add(map);
}
//Adapter
listItemAdapter = new CheckboxAdapter(this, listData);
list.setAdapter(listItemAdapter);
}
//Incident Response

boolean[] array = new boolean[5];
array[0] = CheckboxAdapter.isChecked();
intent.putExtra("status", array);
HashMap<Integer, Boolean> state =listItemAdapter.state;
String options="Medicine Selected:";
for(int j=0; j<listItemAdapter.getCount(); j++)
{
