Answer 1

 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());

    }

}));

在您的代码中，您每次都分配第 0 个（第一项）元素来编辑文本。
