java - SharedPreferences in a game -


hello stackoverflow community, have problem sharedprefs , dont (im beginner) want make simple game stuck @ hiscore.it allways displays o. code snippets.

 mainactivity:  sharedpreferences prefs;  sharedpreferences.editor editor;  prefs = getsharedpreferences("hiscores", mode_private);  long longestdistance = prefs.getlong("longestdistance", 1000000);   gameactivity:  private sharedpreferences prefs;  private sharedpreferences.editor editor;  prefs = context.getsharedpreferences("hiscores", context.mode_private);  editor = prefs.edit();  longestdistance = prefs.getlong("longestdistance", 1000000);   private void update() {  if(distancetaken < longestdistance) {  editor.putlong("longestdistance", distancetaken);  editor.commit();  longestdistance = distancetaken;  }  if(distancetaken >= 100000) {  distancetaken = 100000;  gameended = true;  }  private void startgame(){  distancetaken = 0;  }

thank :) niclas

your if statement judge longest distance wrong,i think want distance longer longest ever,then save it,but mistaken this:

 if(distancetaken < longestdistance) {      editor.putlong("longestdistance", distancetaken);      editor.commit();      longestdistance = distancetaken;  }

should be:

 if(distancetaken > longestdistance) {      editor.putlong("longestdistance", distancetaken);      editor.commit();      longestdistance = distancetaken;  }

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
