In case TextView and Button turn red in Android Studio

This just happened to me for some reason, but I found a fix, so I am sharing it. Your import from the top of the FunFactsActivity.java file might be missing these 2 lines of code, thus being unable to compile.

import android.widget.Button;
import android.widget.TextView;

After adding these 2 lines, everything compiles just fine.

this happens when you dont use autocomplete. If you use autocomplete, android studio automatically imports the classes for you. if you dont use autocomplete, you will have to import them yourself

Apparently that's not necessarily true since in my case auto-complete was in fact on. I think it's a beta caused issue, which is why I posted the tip.

I meant that you have to select/press enter to select the auto completed value when typing Button, text view etc to get the class to auto import, not have autocomplete on or off. If you type out Button yourself without using the autocompleted value then it wont import them. I think this is the normal behavior of android studio

I see. Well, yes, in that case you were right. That is indeed the reason. Brilliant. Now we all know why that could happen. :)
