I have Horizontalscrollview and i added Imageviews dynamically but onLongPress I want checkboxes to come on each image inside scroll view at the top right corner of each image,and delete Image views that are checked.
And,also the new imageview created is shown last inside scrollview.How to show the latest image view created first inside HorizontalScrollView.
My Output and I want something like this
activity_main:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
