The solution to the failure of the three physical buttons caused by the use of the floating window

After clicking the floating window, the three physical buttons fail:

Be sure to connect the settings like this, separated by "|".

params.flags= WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE| WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL ;

It is not possible to set this separately, it will cause only the home button to be used :

params.flags= WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
params.flags= WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL ;
