Reverse the direction of a LinearLayout

Question

How can I reverse the direction of a linear layout?

for example, if my layout is [view1, view2, view3] I want to create [view3, view2, view1]. My goal is to inflate a left and a right handed instances from one XML layout.

Answer 1

Generally I would say you cannot do this using the standard SDK. You could however create a method which gets all of the subviews out of the LinearLayout, removes them from the LinearLayout, and then adds them back in reverse order.

LinearLayout ll = // inflate
ArrayList<View> views = new ArrayList<View>();
for(int x = 0; x < ll.getChildCount(); x++) {
    views.add(ll.getChildAt(x));
}
ll.removeAllViews();
for(int x = views.size() - 1; x >= 0; x--) {
    ll.addView(views.get(x));
}

Answer 2

Just add the following code to LinearLayout:

android:layoutDirection="rtl"

But it permanently reverses the order - not just for RTL locales :(
