hop of those help? For starters, in your constructor just change it to use the ArrayList from
code :
public WeatherAdapter(Context context, int layoutResourceId, Weather[] data)
public WeatherAdapter(Context context, int layoutResourceId, ArrayList<Weather> data)
 Weather data[] = null;
ArrayList<Weather> data = null;

Any of those help Your assumption that Collections.sort( returns the sorted collection is wrong.
code :
mAdapter = new CoursesItemAdapter(getActivity(),
            Collections.sort(parserJson.getCourses(), new CoursesPriceComparator()));
ArrayList< CoursesData > data = parserJson.getCourses();
Collections.sort(parserJson.getCourses(), new CoursesPriceComparator())
mAdapter = new CoursesItemAdapter(getActivity(),

should help you out You can't use the ArrayAdapter in this way.

code :
 ArrayAdapter<PipelineGridViewClass> arrayAdapter = new ArrayAdapter<PipelineGridViewClass>(

hope this fix your issue I'm trying to get ArrayList with different variables that i'm getting from a database to display in a customized listview , adapter calls from your main activity should be like,
code :
CusatomeAdapter adapter;        
adapter = new CusatomeAdapter(mActivity,mList1 ,mList2);        
public class CusatomeAdapter extends BaseAdapter {
    public ArrayList<String> mList1;
    public ArrayList<String> mList2;
    Activity activity;

    public CusatomeAdapter(Activity activity,ArrayList<String> mList1 , ArrayList<String> mList2){
        this.activity = activity;
        this.mList1 = mList1;
        this.mList2 = mList2;

    public int getCount() {
        return mList1.size();   //give the size of list here

    public Object getItem(int position) {
        return null;

    public long getItemId(int position) {
        return 0;

    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        LayoutInflater inflater = activity.getLayoutInflater();

        if (convertView == null) {
            convertView = inflater.inflate(R.layout.row_detail, null);
            holder = new ViewHolder();
            holder.tv_detail = (TextView) convertView.findViewById(R.id.tv_detail);

            //same way define another text view and set their value ..

        } else {
            holder = (ViewHolder) convertView.getTag();

        return convertView;

    private class ViewHolder {
        TextView tv_detail;
AutoCompleteTextView Custom ArrayAdapter showing whole ArrayList instead of separate strings

AutoCompleteTextView Custom ArrayAdapter showing whole ArrayList instead of separate strings

I think the issue was by ths following , It looks like the response that you are seeing is "[search_term, [result1, result2...]]", so when you are parsing you are getting an array of length two: "[search_term, everything_else]". The following parses the "everything_else" which is what interests you. I recommend that you just use this as a starting point since you may need to do some additional error checking:
code :
    JSONArray terms = new JSONArray(builder.toString());
    terms = new JSONArray(terms.get(1).toString());
Android Studio Custom ArrayAdapter passing HashMap instead of ArrayList

I hope this helps you . Using an ArrayList that is not possible.
That is because there is no constructor of ArrayAdapter that accepts a HashMap. If you see the ArrayAdapter source code on line 105, you will see it uses a List internally to store its items.
