android - Show a view when keyboard hides and vice versa -


below app looks like. messaging app.

enter image description here

there 2 fragments in 1 screen fragment1 (beige color) , fragment2 (dark grey color). edittext , "+" button inside fragment2. fragment1, edittext , + button visible.

  1. when click on edittext, keyboard comes up, , edittext , + button comes above keyboard.

  2. when click on + button layout2 of fragment2 visible , keyboard hides if visible.

  3. if click on edittext , layout2 visible layout2 hides , keyboard comes up.

now problem switching keyboard layout2 , vice versa not smooth. screen kinda flickers. want is:

  1. if keyboard visible , click + button, edittext , + button should stay there, keyboard should go down , layout2 should come up.

  2. if layout2 visible , click on edittext, there 2 possibilities.

    a. either edittext , + button should stay there, layout2 should go down , keyboard should come smoothly.

    b. or edittext, + button should stay there, keyboard should come , layout should go down after.

my user experience kinda bad these jerks , flickers. please me out in implementing smooth transition.

you can solve problem : 

layout2.setvisibility(view.gone);   edittext.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 if(booleanisclicked){                   layout2.setvisibility(view.visible);                 }             }         });

or 

edittext.setonfocuschangelistener(.....   layout2.setvisibility(view.visible);  .)

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
