Transferring data from one activity to the other

[c_bigg]

Hello, I am new to android studio and I am trying to figure out how send data from one activity to the other. Im sure it has something to do with intent, but otherwise I am not sure. I have a textview in my second activity where I want to transfer the data from the first activity. The app will get the user to enter weight, height, age, and activity level. the app will calculate bmr and then give the user a calorie goal they need to either lose or gain weight. I have attached a pic of what my current main looks like. I am not sure that the current code is what I am expecting. I have been trying to find a way to view if the variables are holding what I expect
