Counting visible elements in a layout

Question

Suppose in my LinearLayout (say parentLayout) there are 5 other LinearLayouts (say childLayout), where only one of them are visible at the moment. The other layouts depend on some external event to make them visible. How do I count the number of childLayout in the parentLayout that are visible ?

Answer 1

You can iterate over the children of the parent layout and check their visibility. Something like this:

LinearLaout parent = ...;
int childCount = parent.getChildCount();
int count = 0;
for(int i = 0; i < childCount; i++) {
    if(parent.getChildAt(i).getVisibility() == View.VISIBLE) {
        count++;
    }
}
System.out.println("Visible children: " + count);
