Em chào mọi người.
Em sử dụng getDeclaredMethod để show toast nhưng khi run thì không thấy gì. Em chưa biết mình sai chỗ nào, mong mọi người giúp đỡ ạ.
Class toast = Class.forName("android.widget.Toast");
Object mToast = toast.newInstance();
Method make = toast.getDeclaredMethod("makeText", Context.class, CharSequence.class, int.class);
Method show = toast.getDeclaredMethod("show", null);
make.invoke(mToast, getBaseContext(), "Hello", Toast.LENGTH_LONG);
show.invoke(mToast, null);
Nó phải thế này em ạ
Class toast = Class.forName("android.widget.Toast"); // Object mToast = toast.newInstance(); không thể tạo được đối tượng vì Toast không có hàm tạo không đối Method make = toast.getDeclaredMethod("makeText", Context.class, CharSequence.class, int.class); Method show = toast.getDeclaredMethod("show", null); Object toastInstance = make.invoke(null, getBaseContext(), "Hello", Toast.LENGTH_LONG); show.invoke(toastInstance);Cảm ơn a nhiều ạ, để em thử
