get and set global variables from CustomListViewAdapter

Am looking to create a fragment conaining listview by retriveing data from firebase database.This listview gets cards having buttons and seekbar. All I want is to have a global variable listen to these buttons. I tried creating onClicklistener in the fragment itself but wasn't successful.Then I created onClicklistener for these buttons on the Adapter itself which was working. Now when I use the buttonclick to create a Toast, the Toast string is coming up as I expect. But the problem is that I want this Toasted string to store somewhere like global variable so that I could use it in another fragment as well. So I used:
String alpha = ((MyApplication) getContext()).getCartitem();
((MyApplication)getContext()).setCartitem("XYZ");
inside my adapter class's on Click Listener itself but the application crashes showing error log "First cannot be cast to com.fastfrooot.fastfrooot.MyApplication". First being my Activity containing Fragment and MyApplication is the class extending application.
MyApplication.java
package com.fastfrooot.fastfrooot;
import android.app.Application;
import android.widget.Button;
public class MyApplication extends Application {
private boolean[] cartsitem = {
false,
false,
false,
false,
false,
false
};
private String orderitem;
private String pkname;
private boolean oncomp = false;
private Button[] cartbuttons = new Button[20];

GridView is not showing retrieved data from Json

I have a gridview which should show emojies that are retrieved from the server as urls, I was able to retrieve the urls and put it inside an arraylist, however using the gridview adapter, no images show at all, I've tried debugging by handcoding the url outside the for loop and it showed the image, which means that nothing is wrong with my adapter, also when I try to hardcode the url inside the for loop like arraylist.add("the url") no image appears, here's my code, please advise why the images are not showing, appreciate your assistance

Custom Adapter starts before ArrayList is ready

I'm making a list of links and for that I have made a custom adapter, but the list is not ready when the adapter starts so I get the following error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{}: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object android.content.Context.getSystemService(java.lang.String)' on a null object reference
this is because when the adapter is started the list is empty, and just moments after the list is filled but it's too late here is my code:
UPDATE: the code has been changed so now I du not get the error but it doesn't run getView in the adapter:
public class Controller extends Activity {
private String TAG = Controller.class.getSimpleName();
private String http;
CustomAdapter adapter;
public Controller con = null;
private ListView lv;
private static String url;
ArrayList<Selfservice> linkList = new ArrayList<Selfservice>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_view);
con = this;
http = this.getString(R.string.http);
url = this.getString(R.string.path1);
new GetLinks().execute();
lv = (ListView)findViewById(R.id.list);
//Resources res = getResources();
//adapter = new CustomAdapter(con, linkList, res);
//lv.setAdapter(adapter);
}
private class GetLinks extends AsyncTask<Void, Void, List<Selfservice>> {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected List<Selfservice> doInBackground(Void... arg0) {
Document doc;
Elements links;
List<Selfservice> returnList = null;
try {
doc = Jsoup.connect(url).timeout(0).get();
links = doc.getElementsByClass("processlink");
returnList = ParseHTML(links);
} catch (IOException e) {
e.printStackTrace();
}
return returnList;
}
#Override
protected void onPostExecute(final List<Selfservice> result) {
super.onPostExecute(result);
runOnUiThread(new Runnable() {
#Override
public void run() {
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
//setSupportActionBar(toolbar);
//getSupportActionBar().setDisplayShowTitleEnabled(false);
toolbar.setTitle("");
toolbar.setSubtitle("");
Resources res = getResources();
Log.e(TAG, linkList.toString());
linkList = (ArrayList<Selfservice>) result;
adapter = new CustomAdapter(con, result, res);
adapter.notifyDataSetChanged();
lv.setAdapter(adapter);
}
});
}
}
and my adapter:
public class CustomAdapter extends BaseAdapter implements OnClickListener {
private String TAG = CustomAdapter.class.getSimpleName();
Context context;
List<Selfservice> data;
private Activity activity;
public Resources res;
Selfservice self = null;
private static LayoutInflater inflater;
int layoutResourceId = 0;
public CustomAdapter(Activity act, List<Selfservice> dataList, Resources resources) {
res = resources;
activity = act;
data = dataList;
}
private class Holder {
TextView title;
TextView link;
}
#Override
public int getCount() {
return data.size();
}
#Override
public Object getItem(int pos) {
return pos;
}
#Override
public long getItemId(int pos) {
return pos;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = convertView;
Holder holder;
if(rowView == null){
rowView = inflater.inflate(R.layout.list_item, null);
holder = new Holder();
holder.title = (TextView) rowView.findViewById(R.id.title);
holder.link = (TextView) rowView.findViewById(R.id.link);
rowView.setTag(holder);
}else{
holder = (Holder)rowView.getTag();
}
if(data.size()<=0){
holder.title.setText("did not work");
}else{
self = null;
self = (Selfservice) data.get(position);
holder.title.setText(self.getTitle());
holder.link.setText(self.getLink());
Log.i(TAG, "adapter");
rowView.setOnClickListener(new OnItemClickListener(position));
}
return rowView;
}
#Override
public void onClick(View v){
Log.v("CustomAdapter", "row clicked");
}
private class OnItemClickListener implements OnClickListener{
private int mPos;
OnItemClickListener(int position){
mPos = position;
}
#Override
public void onClick(View arg0){
Controller con = (Controller)activity;
con.onItemClick(mPos);
}
}
}
So How do I get the adapter to wait to the list is full?

firstly use ArrayAdapter<Selfservice> instead of BaseAdapter
use constructor
public CustomAdapter(Context context, int resource, List<Selfservice> objects) {
super(context, resource, objects);
data = objects;
}
then override only two methods
public int getCount()
public View getView(int position, View convertView, ViewGroup parent)
then return list.size() in getCount()
in getView() method
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.list_item, null);
}
in doInBackground() method in the try block
instead of linkList = ParseHTML(links);
do linkList.addAll(ParseHTML(links));
and in onPostExcecute() method
adapter.notifyDatasetChanged(); in the ui thread

You can create the adapter in the onPostExecute;
Change the Async Task to this:
private class GetLinks extends AsyncTask<Void, Void, List<Selfservice>> {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected Void doInBackground(Void... arg0) {
Document doc;
Elements links;
List<Selfservice> returnList
try {
doc = Jsoup.connect(url).timeout(10000).get();
links = doc.getElementsByClass("processlink");
returnList = ParseHTML(links);
} catch (IOException e) {
e.printStackTrace();
}
return returnList;
}
#Override
protected void onPostExecute(List<Selfservice> result) {
super.onPostExecute(result);
runOnUiThread(new Runnable() {
#Override
public void run() {
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
//setSupportActionBar(toolbar);
//getSupportActionBar().setDisplayShowTitleEnabled(false);
toolbar.setTitle("");
toolbar.setSubtitle("");
linkList = result
adapter = new CustomAdapter(con, result, res);
lv.setAdapter(adapter);
}
});
}
This way you will only create the adapter when your list is ready.
Edit:
You are not creating the variable context inside your adapter. Change your constructor to this:
public CustomAdapter(Context context, Activity act, List<Selfservice> dataList, Resources resources) {
res = resources;
activity = act;
data = dataList;
this.context = context;
}
And you will stop seeing the NullPointerExecption

You are not getting value because your list is empty.
replace this
new MyTask(getActivity(), mMyList,mMyAdapter).execute(mChosenOrder);
to this
mMyList = new MyTask(getActivity(), mMyList,mMyAdapter).execute(mChosenOrder).get();

ListView with customView and onClickItemListener

i have problem with listview... i'm trying to add OnClickListener but in still doesn't work. I want to display another activity after click. Can somebody help me? I know that there are many of example, but it's doesn't work for my appl or i don't know how to use it in my example...
This is my LocationAdapter class:
public class LocationAdapter extends ArrayAdapter<LocationModel> {
int resource;
String response;
Context context;

public LocationAdapter(Context context, int resource, List<LocationModel> objects) {
super(context, resource, objects);
this.resource = resource;
mInflater = LayoutInflater.from(context);
}
static class ViewHolder {
TextView titleGameName;
TextView distanceGame;
}
public View getView(int position, View convertView, ViewGroup parent)
{
ViewHolder holder;
//Get the current location object
LocationModel lm = (LocationModel) getItem(position);
//Inflate the view
if(convertView==null)
{
convertView = mInflater.inflate(R.layout.item, null);
holder = new ViewHolder();
holder.titleGameName = (TextView) convertView
.findViewById(R.id.it_location_title);

} else {
holder = (ViewHolder) convertView.getTag();
}
holder.titleGameName.setText(lm.getGameName());
holder.distanceGame.setText(lm.getGameDistance()+" km");
return convertView;
}
}
This is my mainListView class:

}
}
EDIT:: I have second problem... i want to get id from item (items are downloading from json url) This is my list:
I want to get for example: ID:159 for first item and send it to nextActivity.
I have also the controllerClass.java where i'm setting and getting selectedIdGame:
public String getIdGameSelected() {
return idGame;
}
public void setIdGameSelected(String idGame) {
this.idGame = idGame;
}
Is it good idea? Thanks for help.
Ok, it's done. i used:
public void onItemClick(AdapterView<?> a, View
v, int position, long id) {
String idGame = (String) ((TextView) v.findViewById(R.id.idGameSelected)).getText();
Thanks, Michal.

You could define an onItemClick on your adapter instance (i.e. in mainListView.java, just after lv.setAdapter):
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> a, View
v, int position, long id) {
Intent i = new Intent(v.getContext(), NextActivity.class);
startActivity(i);
}
});

lv.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
Intent i = new Intent(view.getContext(), NextActivity.class);
startActivity(i);
}
});
I don't know why this wouldn't work, put it after the try{}catch{} block.
