Question

I have 3 booleans which indicate if an int should be added to a list or not, then I would like to use TextUtils.join() on this list.

How should I proceed ?

ArrayList<Integer> types = new ArrayList<Integer>();

if (m_bWithA) {
   types.add(this.TYPE_A); //TYPE_A is an int
}
if (m_bWithB) {
   types.add(this.TYPE_B); 
}
if (m_bWithC) {
   types.add(this.TYPE_C); 
}

TextUtils.join("|", types);

But it says that we can only use TextUtils.join() on Object[].

Should I use another function or a different type of object ?

Answer 1

use TextUtils.join(types.toArray())
