Re-arrange the view order on Framelayout android

Solution

how to re arrange the childIndex of framelayout.

The `FrameLayout` doesn't have the ability to re arrange its children directly but you can do it by removing those children and re adding them in the right positions. Your code doesn't work because you remove the views in an incorrect order resulting in views still being attached to the parent:

fromindex  = 3;
toindex    = 4;
View tempFrom = frameLayout.getChildAt(fromindex);
View tempTo   = frameLayout.getChildAt(toindex);
// first remove the view which is above in the parent's stack
// otherwise, if you remove the other child you'll call the `removeViewAt`
// method with the wrong index and the view which was supposed to be detached
// from the parent is still attached to it
frameLayout.removeViewAt(toindex);
frameLayout.removeViewAt(fromindex);
// first add the child which is lower in the hierarchy so you add the views
// in the correct order
frameLayout.addView(tempTo,fromindex)
frameLayout.addView(tempFrom, toindex)
