try d.setContentView(R.layout.dialog); where dialog layout should contain spinner, — Bapusaheb Shinde, Sep 04 '17 at 07:11
You have not added spinner view in dialog. You need to add view. — Samir Bhatt, Sep 04 '17 at 07:18

try this i think you forgot to setContentView to your dialog set layout to your dialog like below code

@Override
public void onClick(View view) {
    dialog d = new dialog(MainActivity.this) ;
    d.setContentView(R.layout.yourLayout);// set layout to your dialog

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this,
    android.R.layout.simple_spinner_dropdown_item,
        R.array.devise_spin);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    s=(Spinner)d.findViewById(R.id.spinner);
    s.setAdapter(adapter);
    d.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    d.show();
}
