Item in listview showing package name

Question

I want to show data from my json to my listview. Here is what i try

   private void loadIntoListView(String json) throws JSONException {
        List<Itemadapter> items = new ArrayList<Itemadapter>();
        JSONArray jsonArray = new JSONArray(json);
        String[] ba = new String[jsonArray.length()];
        for (int i = 0; i < jsonArray.length(); i++) {
            JSONObject obj = jsonArray.getJSONObject(i);
            String code     = obj.getString("ItemCode");
            String name     = obj.getString("ItemName");
            String photo    = obj.getString("PhotoName");
            items.add(new Itemadapter(code, name,photo));
            Log.i(code, code);

        }
        Toast.makeText(getActivity(), items.toString(), Toast.LENGTH_LONG).show();

        ArrayAdapter<Itemadapter> mArrayAdapter = new ArrayAdapter<Itemadapter>(getActivity(),android.R.layout.simple_expandable_list_item_1,items);
        listView.setAdapter(mArrayAdapter);
    }

My Itemadapter

public class Itemadapter {

    String ItemCode;
    String ItemName;
    String ItemPhoto;

    public Itemadapter(String ItemCode, String ItemName, String ItemPhoto) {
        this.ItemCode   = ItemCode;
        this.ItemPhoto  = ItemPhoto;
        this.ItemName   = ItemName;
    }

    public String getCode() {
        return ItemCode.toString();
    }

    public String getItemPhoto() {
        return ItemPhoto.toString();
    }

    public  String getItemName(){
        return ItemName.toString();
    }

}

when i run it, there is no error . But, in my listview i see something like this in multiplerows

com.example.boby.firstapp.Itemadapter@(somecode)

How can i fix it ? did i miss something ?

You need to override toString() in Itemadapter:

public class Itemadapter {

    String ItemCode;
    String ItemName;
    String ItemPhoto;

    public Itemadapter(String ItemCode, String ItemName, String ItemPhoto) {
        this.ItemCode   = ItemCode;
        this.ItemPhoto  = ItemPhoto;
        this.ItemName   = ItemName;
    }

    public String getCode() {
        return ItemCode.toString();
    }

    public String getItemPhoto() {
        return ItemPhoto.toString();
    }

    public  String getItemName(){
        return ItemName.toString();
    }

    @Override
    public String toString() {
        return ItemCode + " " + ItemName;

}

ArrayAdapter<Itemadapter> mArrayAdapter = new ArrayAdapter<Itemadapter>(getActivity(),android.R.layout.simple_expandable_list_item_1,items);

This error comes because of this line. Let me explain. If you want to show itemCode in listview, then the code must be like this.

ArrayList<String> itemsCode = new ArrayList<>();   
for(int i=0;i<items.size();++i){
    itemsCode.add(item.get(i).getCode());
}
ArrayAdapter<> mArrayAdapter = new ArrayAdapter<>(getActivity(),android.R.layout.simple_list_item_1,itemsCode);

The third parameter should be what you want to display

The error is on the getters methods at ItemAdapter class, remove .toString() from all getters.

public class Itemadapter {

    String ItemCode;
    String ItemName;
    String ItemPhoto;

    public Itemadapter(String ItemCode, String ItemName, String ItemPhoto) {
        this.ItemCode   = ItemCode;
        this.ItemPhoto  = ItemPhoto;
        this.ItemName   = ItemName;
    }

    public String getCode() {
        return ItemCode;
    }

    public String getItemPhoto() {
        return ItemPhoto;
    }

    public  String getItemName(){
        return ItemName;
    }

}

I hope it will help you!
