NotifyDataSetChanged on gridview not working - Android

NotifyDataSetChanged on gridview not working - Android - android

I am working with GridView. I want to update GridView on some basis. But notifyDataSetChanged() method is not working.
I am selecting tables on basis of section name. When I select section name very first time than I got tables of that section. But when I go to sections fragment again and select diff. section than I get previously selected tables only. That means notifyDataSetChanged() is not working.
What I have tried is like below.

At last I got the solution.
I have done like below...
I was maintaining a FLAG called getTableStatus to get the tables of particular section. If the value of getTableStatus is FALSE than only TableStatusAsync is called. At first selection of section, tables are coming from web service and those tables are being inserted in DB.
On second time, selecting of SECTION, tables are coming from DB not from web service. And tables are coming from DB are of previously selected SECTION. So, there is nothing to do with notifyDataSetChanged().
I have just change the FLAG value to FALSE by calling pref.setTableStatus(false); on selection of SECTION. Now, TableStatusAsync is called every time when you change your selection of SECTION.
Modified Code...
TableScreenSectionwiseActivity.java
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
pref.setSectionId(view.getTag().toString());
pref.setTableStatus(false);
pref.setTableServiceStatus(false);
Fragment fragment = new TableScreenActivity();
ReplaceFragment.getReplaceFragment(getActivity(), fragment, "");
}

I am assuming that you are using php over your server.What you can do is send the comma separated travel id's over server like this:-
Put travel id's into an arraylist or array like this:-
ArrayList<String> selectedTravelId= new ArrayList<>();
selectedTravelId.add(travelId); // add travel ids
StringBuilder travelId = new StringBuilder();
for (int i = 0; i < selectedTravelId.size(); i++) {
travelId .append(selectedTravelId.get(i));
if (!(i == selectedTravelId.size() - 1)) {
travelId .append(",");
}
}// to create travelId string
travelId.toString();// to convert StringBuilder to String
After this execute your AsyncTask.
You will get a string like e.g. 1,2,134,142.Now send this travelId to sever.
At server side retrieve
Try explode:
$mytravelId = " 1,2,134,142";
$myArray = explode(',', $mytravelId );
print_r($myArray);
Output :
Array
(
[0] => 1
[1] => 2
[2] => 134
[3] => 142
)

The View objects are recycling and you're using the same ViewHolder object (and other UI components) for both positions. The view being clicked has had its tag updated to the position desired, but the animation object is the same as another position due to the recycling.

Pull to refresh GridView infinite loading/ fails to pull data

I can't seem to figure out what is going wrong with this, the code is pretty clean/ simple, but for some reason when I pull to refresh, it just shows me the loading icon infinity. Not only that, but I don't even receive any errors. The library I used for pull to refresh is this one.
I've spent several hours trying to figure this out, but the fact that it's not even giving me errors is making it very hard for me to track down.
And yes, I am sure the rest request is working.

imageLoader = new ImageLoader(activity.getApplicationContext());
}
public int getCount() {
return data.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.mobile, null);
TextView name = (TextView) vi.findViewById(R.id.grid_item_label); // title
SmartImageView thumb_image = (SmartImageView) vi
.findViewById(R.id.grid_item_image);
HashMap<String, String> update = new HashMap<String, String>();
update = data.get(position);
// Setting all values in listview
name.setText(update.get("name"));
thumb_image.setImageUrl(update.get("thumb_img"));
name.setOnClickListener(new myOnClickListener(position));
thumb_image.setOnClickListener(new myOnClickListener(position));
return vi;
}
public class myOnClickListener implements OnClickListener {
private int position;
private String clicked_uid;
public myOnClickListener(int position) {
this.position = position;
}
#Override
public void onClick(View v) { // TODO Auto-generated method stub
HashMap<String, String> update = new HashMap<String, String>();
update = data.get(position);
Log.i("Update Position:", update.toString());
clicked_uid = update.get("uid");
Log.d("Clicked UID:", clicked_uid + "");
Intent i = new Intent(activity.getApplicationContext(),
TabHostFragmentActivity.class);
i.putExtra("profile_uid", clicked_uid);
activity.startActivity(i);
}
}
}

You should POST to 10.0.2.2 instead of localhost in the call to RestClient.post in RestClientUsage.
I am not familiar withJsonHttpResponseHandler, but I would image there's an onFailure method (or something similar) that you may want to override. If there is, you may way to call mPullRefreshGridView.onRefreshComplete() in it.
