I am incredibly new to Android Studio and was hoping to get some assistance. For some reason, this code is only displaying the ("Hi, " name) portion. I am not sure what I am doing wrong or how to get the ("You must enter a name") portion to show when there is no text that has been inputted. We are needing to incorporate a SayHello() function into this and I am not sure if I am doing it properly...

try this and do let me know if it works !!
