Could not get or set edittext value from separate OnClickListener class using android studio 3 - android-studio-3.0

Question

Using eclipse i was able to get edittext value from separate onclicklistener class, but after i transfer the same style of code to android studio 3 the edittext returns empty here is my code
public class MainActivity extends AppCompatActivity {
Button btnGenerate;
private static final String TAG = MainActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//getting the generate_btn actually works
btnGenerate = findViewById(R.id.generate_btn);
btnGenerate.setOnClickListener(new OnClickListenerGenerate());
}
}
And here is the OnClickListener class
public class OnClickListenerGenerate implements View.OnClickListener {
EditText second_digit;
private static final String TAG = OnClickListenerGenerate.class.getSimpleName();
#Override
public void onClick(View view) {
final Context context = view.getRootView().getContext();
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View formElementsView = inflater.inflate(R.layout.activity_main, null, false);
second_digit = formElementsView.findViewById(R.id.txtSecondDigit);
//returns empty
Log.d(TAG, ">>" + second_digit.getText().toString());
}
}

I found the answer from this link Android::findViewByID - how can I get View of a TextView through a Listener of another UI element? and now it's working.
class ButtonListener implements android.view.View.OnClickListener {
public void onClick(View v) {
View parent = (View)v.getParent();
if (parent != null) {
TextView txtView = parent.findViewById(R.id.mytextview);
txtView.setText(...);
}
}
}
