With the following the myList[rando]
is underlined and it says "The type of expression must be an array type but it resolved to List"
textView.setText(myList[rando]);
Here is my code:
public void OnButtonClickDisplayFact(View view)
{
List<String> myList = new ArrayList<String>();
myList.add("111");
myList.add("222");
myList.add("333");
int rando = (int) (Math.random() * 3);
TextView textView = (TextView)findViewById(R.id.randomFactText);
textView.setText(myList[rando]);
}
To access elements of an array list, use the get method, that is
myList.get(rando)
myList[rando]
only works for arrays
You're using array notation where get
is required
textView.setText(myList.get(rando));
