 public DialogClass(){} String s; String s1; @Nullable @Override public View onCreateView( LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) { final View dialogView= View.inflate(getActivity(), R.layout.dialog, null); getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE); final EditText e1 = dialogView.findViewById(R.id.text1); final EditText e2= dialogView.findViewById(R.id.text2); Button bt = dialogView.findViewById(R.id.button); bt.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view){ s = e1.getText().toString(); s1 = e2.getText().toString(); dismiss(); } }); return dialogView; }

}

Answer 1

It's probably that in your dialog.xml layout you haven't the editTexts with the IDs "text1" and "text2".

The IDs can be different.
