which version of android studio are you using?

@muhammadardialfianto6493 8 ай бұрын

1:39 you type in your code in this arrangement : android:layout_gravity="center" android:textStyle="bold" android:textSize="30sp" It should be in that order ? Or we can put it in randomly ? And, does this code work for Android Studio Giraffe ?

@CodesEasy 8 ай бұрын

You can put it to the element you want to apply these properties, any order is fine

hello sir thanks for sharing the education, i have question for you, why you use linear layout instead use constraint layout? imo constraint layout more option for layout, thanks for answer

@CodesEasy Жыл бұрын

You can use constraint layout, for this a constraint layout will be a better option too. It's just easier for beginners to understand with linear layout

How to resolve the error "Constant expression required" on case R.id.btn_add:?

@CodesEasy Жыл бұрын

This happens if you use Resources from a Library project. In that case, the the ids in the R class are not really constants and thus cannot be used in a switch statement.
