Android的 - 优化多个if语句 [英] Android - Optimising multiple if-statements

问题描述

在我的申请，我有很多的IF可能被优化的语句，但对我的生活不能工作了没有错误了良好的解决方案。

In my application, I have many IF statements that could be optimizing, but for the life of me can't work out a good possible solution without errors.

我目前的code：

    if (User_XP > -1){User_level.setText("1");Minimum_Level= Level1; Maximum_level = Level2;}
    if (User_XP > Level1){User_level.setText("1");Minimum_Level= Level1; Maximum_level = Level2;}
    if (User_XP > Level2){User_level.setText("2");Minimum_Level = Level2; Maximum_level = Level3;}
    if (User_XP > Level3){User_level.setText("3");Minimum_Level = Level3; Maximum_level = Level4;}
    if (User_XP > Level4){User_level.setText("4");Minimum_Level = Level4; Maximum_level = Level5;}
    if (User_XP > Level5){User_level.setText("5");Minimum_Level = Level5; Maximum_level = Level6;}
    if (User_XP > Level6){User_level.setText("6");Minimum_Level = Level6; Maximum_level = Level6;}
    if (User_XP > Level7){User_level.setText("7");Minimum_Level = Level7; Maximum_level = Level6;}
    if (User_XP > Level8){User_level.setText("8");Minimum_Level = Level8; Maximum_level = Level6;}
    if (User_XP > Level9){User_level.setText("9");Minimum_Level = Level9; Maximum_level = Level6;}

它的想法是制定出一个用户从游戏的水平，并从创建一个百分比。但是，编码这方面实在是没有效率的，因为它可以创建多个错误，任何人有一个可能的解决方案什么秘诀？
如果需要了解更多信息请咨询。

The idea of it is to work out a users level from a game, and from that create a percentage. But this area of coding is really not efficient as it can create multiple errors, anyone got any tips on a possible solution? Please ask if more information is needed.

推荐答案

也许您的存储级经验要求一个数组，并使用循环。

Perhaps store your level experience requirements in an array and use a loop.

int[] levels = new int[] { -1, Level1, Level2, Level3 };

int level;
for (level = 0; level < levels.length && userXp < levels[level]; level++) { }
int minLevel = levels[level];
int maxLevel = levels[level + 1];
userLevelText.setText(Integer.toString(minLevel));
