create your own `interface` here. register it inside your `MainActivity` or `Fragment` where is your recycler view. set it inside adapter of recycler view and on clicking of any item of recycler view call that interface method with position of item. — Radhey, Mar 23 '18 at 08:03
use `position` AS `et_kodepos.setText(data.get(position).getPosKode());` — ADM, Mar 23 '18 at 08:03
@ADM sir, can i ask you some question. How to make the dialog closed after I clicked the item ? — Lisda Wijayanti, Mar 26 '18 at 03:54
To dismiss Dialog See https://stackoverflow.com/a/49349852/4168607 . — ADM, Mar 26 '18 at 04:04
Sir, once again i want to ask you how i get position after i search an item then when i click it , it will set in edit text ? @ADM — Lisda Wijayanti, Mar 26 '18 at 08:01
These little problems you are facing because your code is not structurized and you did not get understand the concept. Read documentation and working of elements you are using and Look for tutorials for each step and combine them. `position` is an parameter of `onItemClick` which you can use . And to get Item from `position` get it from `filteredList` not from `completeList`. It will be clear if you make a separate class for `Dialog` and use `interface` for callback See [How to Define Callbacks in Android](https://stackoverflow.com/questions/3398363/how-to-define-callbacks-in-android). — ADM, Mar 26 '18 at 08:07

 recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(AddCustomerActivity.this, new RecyclerItemClickListener.OnItemClickListener() {
    @Override
    public void onItemClick(View view, int position) {


        et_kodepos.setText(data.get(position).getPosKode());
        et_kota.setText(data.get(position).getPosKota());
        et_provinsi.setText(data.get(position).getPosProp());
        et_kecamatan.setText(data.get(position).getPosCamat());
        et_kelurahan.setText(data.get(position).getPosLurah());

    }

}));

In your code, every time, you are assigning the 0th (first item) element to edit text.
