I was questioning, arsenic I’m seeing it much and much frequently, is that a constructed-successful characteristic that you tin someway entree successful an act? I’ve regarded astatine the origin codification of galore lessons however I tin’t look to discovery thing astir that.
Of class, I tin deliberation astir a fewer methods to accomplish the aforesaid performance rather easy (the best is most likely to support a boolean successful the act that signifies whether or not the person already clicked erstwhile…) however I was questioning if location’s thing already present.
EDIT: Arsenic @LAS_VEGAS talked about, I didn’t truly average “exit” successful the conventional which means. (i.e. terminated) I meant “going backmost to any was unfastened earlier the exertion commencement act was launched”, if that makes awareness :)
Successful Java Act:
boolean doubleBackToExitPressedOnce = mendacious; @Override national void onBackPressed() { if (doubleBackToExitPressedOnce) { ace.onBackPressed(); instrument; } this.doubleBackToExitPressedOnce = actual; Toast.makeText(this, "Delight click on Backmost once more to exit", Toast.LENGTH_SHORT).entertainment(); fresh Handler(Looper.getMainLooper()).postDelayed(fresh Runnable() { @Override national void tally() { doubleBackToExitPressedOnce=mendacious; } }, 2000); }
Successful Kotlin Act:
backstage var doubleBackToExitPressedOnce = mendacious override amusive onBackPressed() { if (doubleBackToExitPressedOnce) { ace.onBackPressed() instrument } this.doubleBackToExitPressedOnce = actual Toast.makeText(this, "Delight click on Backmost once more to exit", Toast.LENGTH_SHORT).entertainment() Handler(Looper.getMainLooper()).postDelayed(Runnable { doubleBackToExitPressedOnce = mendacious }, 2000) }
I Deliberation this handler helps to reset the adaptable last 2 2nd.
