How can I set the priority of an android floating window to hover the self-written floating window over all floating windows and drop-down menus?

If it is set to phone type, it can always be at the top, because the call level is higher than anything else.

This. getWindow (). setType (WindowManager. LayoutParams. TYPE_PHONE );

How does one implement countdown in the android floating window?
