Error: (23, 31) error: reference to findViewById is ambiguous

where T is a type-variable:
T extends View declared in method <T> findViewById (int)

Answer 1

You're using findViewById (R.id.nombre ) . Where nombre is defined in two activities(Activity and AppCompatActivity) with same name. You should assign different name for nombre in each activity.
