     @Override
 public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
               Model model= (Model) wisataAdapter.getItem(position);

                if(position==0){
                   Intent intent = new Intent(GunungKidul.this, Pantai_Kesirat.class);
                   //To pass whole model data with intent:
                   intent.putExtra("MyClassKey", model);
                   startActivity(intent);

Custom Base Adapter to ListView

Inside the UserRepo class you never initialize ArrayList<user> list. Change the code to initialize it.

public class UserRepo {
    ArrayList<user> list = new ArrayList<>();
    // The rest of your code
}

How can I using Custom baseAdapter to display data in ListView?

change

listAdapter = new FeedListAdapter(this, feedItems);

to

listAdapter = new FeedListAdapter(YourActivity.this, feedItems);

YourActivity is the name of Activity inside which you are calling addValueEventListener.
inside onDataChange method this == ValueEventListener, not an Activity, which is needed for FeedListAdapter creator

Unable to populate custom listView using BaseAdapter in Android

first in onCreateView()

change this

list.setAdapter(new myAdapter(c));

to

list.setAdapter(new myAdapter(this.getActivity()));

because 'c' will be null.

for next,
as in above.

change

for(int i=0;i<10;i++)

to

for(int i=0;i<oneofarray.length;i++)

Duplicate item custom listview with BaseAdapter

Your getView implementation is not correct. Try this -

  @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        TextView tvUsername, tvTitle;

        if (convertView == null) {
            LayoutInflater layoutInflator = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            convertView = layoutInflator.inflate(R.layout.custom_listview_home, parent, false);   
        }


            map = membersList.get(position);

            tvUsername = (TextView) convertView.findViewById(R.id.tvUsername);
            tvTitle = (TextView) convertView.findViewById(R.id.tvTitle);

            tvUsername.setText(map.get(FragmentHome.USERNAME));
            tvTitle.setText(map.get(FragmentHome.TITLE));

        return convertView;
}
