I have a layout with multiple ImageView
s, some of those images need to have the same onClickListener.
I would like my code to be flexible and to be able to get a collection of those View
s, iterate and add the listeners at run-time.
Is there a method like findViewById
that will return a collection of View
s rather than just a single one?
I've finally wrote this method (Updated thanks to @SuitUp (corrected username)):
private static ArrayList<View> getViewsByTag(ViewGroup root, String tag){
ArrayList<View> views = new ArrayList<View>();
final int childCount = root.getChildCount();
for (int i = 0; i < childCount; i++) {
final View child = root.getChildAt(i);
if (child instanceof ViewGroup) {
views.addAll(getViewsByTag((ViewGroup) child, tag));
}
final Object tagObj = child.getTag();
if (tagObj != null && tagObj.equals(tag)) {
views.add(child);
}
}
return views;
}
It will return all views that have android:tag="TAG_NAME"
attribute. Enjoy ;)
