JAVA参数TRUE/FALSE值

Question

在应用中添加一个关闭音量的按钮，实现功能是，当用户调节框时判断true还是false，然后设置为相反。我觉得只要简单改变SharedPreference的truefalse。最开始的框架代码如下：SharedPreferences getPrefs = PreferenceManager.getDefaultSharedPreferences(getBaseContext()); boolean cmute = getPrefs.getBoolean("mute", defValue); if (cmute == true){                      } if (cmute == false){ }后来找到的方法都不够简单：我改成：if (cmute == false){                 Editor editor = getPrefs.edit();                 editor.putBoolean("mute", true);                 editor.commit();                 Editor editor2 = getPrefs.edit();                 editor.putBoolean("notice", true);                 editor.commit();             }             if (cmute == true){                 Editor editor = getPrefs.edit();                 editor.putBoolean("mute", false);                 editor.commit();                 Editor editor2 = getPrefs.edit();                 editor.putBoolean("notice", false);                 editor.commit();             }
