Getting values of edit text error NULLPOINTER why? [closed]

Question

I'm trying to get text from values of edit field showed on a dialog and save it in a variable.

final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialg);
dialog.setTitle("Title...");
dialog.show();
Button dialogButtonCancel = (Button) dialog.findViewById(R.id.cancel);
// if button is clicked, close the custom dialog
dialogButtonCancel.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        dialog.dismiss();}});
Button dialogButtonOK = (Button) dialog.findViewById(R.id.OK);
//***************************************************************************
dialogButtonOK.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        EditText edt1=(EditText)findViewById(R.id.EditTextNom);
        nom = edt1.getText().toString();
        EditText edt2=(EditText)findViewById(R.id.editTextDescription);
        description = edt2.getText().toString();
        dialog.dismiss();
    }});

Answer 1

Try instead

 EditText edt1=(EditText)dialog.findViewById(R.id.EditTextNom);

you need to look in the layout that is inflated for the Dialog. Right now it is looking in the one that was inflated for the Activity and, obviously, those Views don't exist in that layout.
