Question

I was wondering how you check if a scrollView exists for an if statement. The current code for creating the scollView is below. Any help will be much appreciated 🙂

Code:

public void tickBox(int i){
    //Create GUI
    LinearLayout mainView = (LinearLayout) findViewById(R.id.MainLayout);
    ScrollView sc = new ScrollView(this);
    sc.setId(i + 100);
    if (/*If statement to be made*/){
        mainView.addView(sc);
    }
    //My other code
}

Answer 1

it can be as:

if (mainView.findViewById(i + 100) == null){
    mainView.addView(sc);
}
