[Android]AutoComplexEditText is not suggestion in Fragment

Question

I try using AutoComplexEdittext in Fragment but I do not know why it's not working (Don't have logcat, just not show sugesstion). Here is my xml file:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <AutoCompleteTextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text=""
        android:id="@+id/autoCompleteTextView"
        android:completionThreshold="1"
    />
</RelativeLayout>

Here is my AboutFragment:

public class AboutFragment extends Fragment implements TextWatcher{
    private AutoCompleteTextView atv_test;
    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        atv_test = (AutoCompleteTextView)getView().findViewById(R.id.autoCompleteTextView);
        atv_test.addTextChangedListener(this);

        String a[] ={"Abhc","GA","AAA","DDSDS","DDSADSa","dsadsadsahkaz"};
        ArrayAdapter<String> arr = new ArrayAdapter<String>(getView().getContext(),android.R.layout.simple_list_item_1,a);
        atv_test.setAdapter(arr);
        //JSonCityAsyncTask j = new JSonCityAsyncTask();
        //j.execute();
    }

    public void messages(String msg) {
        new AlertDialog.Builder(getActivity()).setTitle("Notification").setMessage(msg).setNeutralButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {

            }
        }).show();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_about, container, false);


        // Inflate the layout for this fragment
        return rootView;
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
    }

    @Override
    public void onDetach() {
        super.onDetach();
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

    }

    @Override
    public void afterTextChanged(Editable s) {

    }
}

Please help me know what is my wrong. Thanks you for reading my question and sorry if this question is stupid.

AutoComplexEditText is not suggestion in Fragment

Because in onActivityCreated arrCity ArrayList object is empty. adding items in arrCity in onPostExecute method.

Set adapter for both AutoCompleteTextView in onPostExecute method :

  @Override
    protected void onPostExecute(ArrayList<CityModel> result) {
        /// 
     arrAdapterCity =new ArrayAdapter<CityModel>(SearchFragment.this.getActivity(),
                                android.R.layout.simple_list_item_1,result);
    et_departure.setAdapter(arrAdapterCity);
    et_arrival.setAdapter(arrAdapterCity);
    }

EDIT:

Also change android.R.layout.simple_list_item_1 to android.R.layout.simple_dropdown_item_1line which is second parameter in ArrayAdapter

I make sure with you it is not empty. I will take a picture for you. So sorry, i copy wrong code – Xiao King Nov 16 '15 at 19:01
It's not working, when I working a first time with autocomplex, I write code like you. But it's not working, and I change it as code in my question, – Xiao King Nov 16 '15 at 19:08
@XiaoKing: i think you also need to create a custom class by extending `ArrayAdapter` because `arrCity` ArrayList contains objects of custom class. see following post [How to use ArrayAdapter](http://stackoverflow.com/questions/2265661/how-to-use-arrayadaptermyclass) – ρяσѕρєя K Nov 16 '15 at 19:19
I don't know what happen with AutoComplexEddittext, I always using this way to load data to ListView. And everything is ok until I try using AutoComplex. I think my problem does not come to Arraylis contains objects, it come to fragment or Autocomplex. I checked by breakpoint and I saw my arraylist have data. Do not know what wrong with it. :( – Xiao King Nov 16 '15 at 19:24
@XiaoKing: but as per my understanding you should create custom adapter class as in http://stackoverflow.com/questions/2265661/how-to-use-arrayadaptermyclass post to get your code work otherwise do a simply test moving with my answer or suggestion : create a simply String type ArrayList with some 4-5 string items then pass it to ArrayAdapter and check getting value or not – ρяσѕρєя K Nov 16 '15 at 19:27
Ok. I will do it, hope it work. thanks for your answers. – Xiao King Nov 16 '15 at 19:29
It's not working also i try create simple array. I will edit my code, and something wrong with fragment or autocomplex – Xiao King Nov 16 '15 at 19:45
@XiaoKing: Change `android.R.layout.simple_list_item_1` to `android.R.layout.simple_dropdown_item_1line` – ρяσѕρєя K Nov 16 '15 at 19:54
@XiaoKing: Following example working fine on my end :http://www.java2s.com/Code/Android/UI/FilldatatoAutoCompleteTextViewwithArrayAdapter.htm – ρяσѕρєя K Nov 16 '15 at 19:57
after change android.R.layout.simple_list_item_1 to android.R.layout.simple_dropdown_item_1line, it works perfect. What is wrong with simple_list_item_1 ? . – Xiao King Nov 16 '15 at 19:59
@XiaoKing: probably it is related to DropDown of `AutoCompleteTextView` – ρяσѕρєя K Nov 16 '15 at 20:01

I see on almost tutorial they always use simple_list_item_1 :(. Thanks you so much. You are my hero :) – Xiao King Nov 16 '15 at 20:04
