android array list null

android array list null - android

I'm designing an Android app that downloads information from a website and prints a list on-screen with that information in the form of an Array List.
However, the ArrayList I use doesn't load correctly and my screen becomes blank.
Activity code:
Tenda.java
public class Tenda extends Activity implements OnItemClickListener, LocationListener {
ProgressDialog lDialog;
String json_string;
SuperAdapter adapter_super;
int user_id;

The main problem is located in this section:
private void refreshListByJson(String json){//line 300
lDialog.dismiss();
Store store=Store.newStore(json);
if (store.getProductes() != null)
{
Log.i("store-nom", "" + store.getStore());//line 305
Log.i("store-producte", "" + store.getProductes().toString()); //line 306
adapter_super.setItems_producte(store.getProductes());
}
}
The "if" condition is not fulfilled: store.getProductes() is null.
It's strange because the app can DL the info from internet and I can see that in the logcat output: for some reason it doesn't load into the ArrayList.
Could you please help me in figuring out what I must do for the ArrayList to work?
Thank you very much.

ListView lsv_producto = (ListView)findViewById(R.id.list_productes);
adapter_super = new SuperAdapter(Tenda.this,null);
lsv_producto.setAdapter(adapter_super);
You are passing null in SuperAdapter cnstructer, you need to pass ArrrayList instead of passing null.

Put condition this way
if (store.getProductes() != null && store.getProductes().size()>0){
}

private ArrayList<Super> productes = new ArrayList<Super>():
You never use your setProducts too so this will be empty.

First Remove the below code
ListView lsv_producto = (ListView)findViewById(R.id.list_productes);
adapter_super = new SuperAdapter(Tenda.this,null);
lsv_producto.setAdapter(adapter_super);
Now modified the refreshListByJson() as below
private void refreshListByJson(String json){//line 300
lDialog.dismiss();
Store store=Store.newStore(json);
if (store.getProductes() != null)
{
Log.i("store-nom", "" + store.getStore());//line 305
Log.i("store-producte", "" + store.getProductes().toString()); //line 306
adapter_super.setItems_producte(store.getProductes());
}
//////////////////
ListView lsv_producto = (ListView)findViewById(R.id.list_productes);
adapter_super = new SuperAdapter(Tenda.this,store.getProductes());
lsv_producto.setAdapter(adapter_super);
////////////////////

As far as i am able to understand your question you want favorite and unfavorite functionality by adapter . Please use this code below to achieve that :

String userId;
String like_dislike_value = "Like";

mContext = c;
this.foodDrinkArrayList = foodDrinkArrayList;

I have to fetch LinkedIn details from the loginned user . I am able to get basic basic details through the below code.
d.setVerifierListener(new OnVerifyListener() {
#Override
public void onVerify(String verifier) {
try {
Log.i("LinkedinSample", "verifier: " + verifier);
accessToken = LinkedinDialog.oAuthService
.getOAuthAccessToken(LinkedinDialog.liToken,
verifier);
LinkedinDialog.factory.createLinkedInApiClient(accessToken);
client = factory.createLinkedInApiClient(accessToken);
Person p = client.getProfileForCurrentUser();
name.setText("Welcome " + p.getFirstName() + " "
+ p.getLastName());
} catch (Exception e) {
Log.i("LinkedinSample", "error to get verifier");
e.printStackTrace();
}
}
Now I want to take education and work details.
Educations items = p.getEducations();
System.out.println("items =="+items);
I got values for p.getfirstname(),p.getlastname() but for p.getEducations() , I got null.
I didn't find any solution anywhere. Please help me
Thanks in advance.

My question is : when I input words in the EditText, nothing happened. But when I press backspace did the AutoCompleteTextView show the suggestion list ... the problem is in the editAuto.setAdapter(adapter);
What is wrong?

make the following changes in your code
1) Instead of
private AutoCompleteTextView editAuto = null; JUST WRITE private AutoCompleteTextView editAuto;
2) Add this line to onCrate()
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, <your array name here>);
and remove this line from onTextChangedTask()
ArrayList<String> userNameArrayList = new ArrayList<String>();
3) Add this line to onCrate()
editAuto.setAdapter(adapter);

I know this is way late but for those who face similar problems here is the solution to show the autoCompleteTextView's drop down whenever you want i.e on button click or onTextChanged. After you set the ArrayAdapter for the autoCompleteTextView just put the following line.
autoCompleteTextView.showDropDown();

Put condition this way if (store.getProductes() != null && store.getProductes().size()>0){ }

private ArrayList<Super> productes = new ArrayList<Super>(): You never use your setProducts too so this will be empty.
