# Android记事本NotePad应用功能拓展（五） #

## 一、实现功能 ##

### 1.夜间模式切换 ###

### 2.反转时间排序规则 ###

## 二、项目代码分析 ##

### 1.夜间模式切换 ###

只要做所有关于界面的地方加上这段代码即可（判断模式设置背景）

if (super.isNightMode())
                myToolbar.setNavigationIcon(getDrawable(R.drawable.ic_menu_white_24dp));
            else myToolbar.setNavigationIcon(getDrawable(R.drawable.ic_menu_black_24dp)); // 三道杠
    
            myToolbar.setNavigationOnClickListener(new OnClickListener() { 
                @Override
                public void onClick(View v) { 
                    showPopUpWindow();
                }
            });

### 2.反转时间排序规则 ###

//按模式时间排序笔记
        public void sortNotes(List<Note> noteList, final int mode) { 
            Collections.sort(noteList, new Comparator<Note>() { 
                @Override
                public int compare(Note o1, Note o2) { 
                    try { 
                        if (mode == 1) { 
                            Log.d(TAG, "sortnotes 1");
                            return npLong(dateStrToSec(o2.getTime()) - dateStrToSec(o1.getTime()));
                        }
                        else if (mode == 2) { //reverseSort
                            Log.d(TAG, "sortnotes 2");
                            return npLong(dateStrToSec(o1.getTime()) - dateStrToSec(o2.getTime()));
                        }
                    } catch (ParseException e) { 
                        e.printStackTrace();
                    }
                    return 1;
                }
            });
        }
    
        //按模式时间排序计划
        public void sortPlans(List<Plan> planList, final int mode){ 
            Collections.sort(planList, new Comparator<Plan>() { 
                @Override
                public int compare(Plan o1, Plan o2) { 
                    try { 
                        if (mode == 1)
                            return npLong(calStrToSec(o1.getTime()) - calStrToSec(o2.getTime()));
                        else if (mode == 2) //reverseSort
                            return npLong(calStrToSec(o2.getTime()) - calStrToSec(o1.getTime()));
                    } catch (ParseException e) { 
                        e.printStackTrace();
                    }
                    return 1;
                }
            });
        }
