====== How to use the script ======

Instructions:
Run the script from a container.
The list of all the items in that container will be shown (type+label+name). The first item of the list is the top most one. The last item the bottom most one.
Choose two of them to exchange their Z order.
Repeat.
Click exit to exit.


Note: I tested it some few times(in fact I had the idea less than two hours ago) and it works, but as usual maybe it don't work in some specific situations. Anyway the script only change the Z order, nothing more.

====== Script code ======
<sxh javascript>

LL.bindClass("android.app.AlertDialog");
LL.bindClass("android.content.DialogInterface");



run(LL.getEvent().getContainer());


function run(cont){


var items=cont.getItems();
var names=[];
var ids=[];

for(var t=0;t<items.getLength();++t){
var it=items.getAt(t);
names[t]=it.getType()+" : "+it.getLabel()+" ["+it.getName()+"]";
ids[t]=it.getId();
}

names=names.reverse();
ids=ids.reverse();



var check=-1;

var builder=new AlertDialog.Builder(LL.getContext());
builder.setTitle("Select two to echange");
builder.setMultiChoiceItems(names,null,new DialogInterface.OnMultiChoiceClickListener(){onClick:function(dialog,which,checked){

//function
var id=ids[which];
if(id==check){check=-1;return;}
if(check==-1){check=id;return;}
//else, echange check and id

var a=cont.getItemZIndex(check);
var b=cont.getItemZIndex(id);
cont.setItemZIndex(id,a);
cont.setItemZIndex(check,b);

run(cont);

dialog.dismiss();

}});


builder.setPositiveButton("Exit",null);

builder.create().show();
}
</sxh>
