详情地址：

底部导航栏四个按钮代表四个颜色，点其中其中一个按钮，则换一种颜色，颜色代码和图标都保存在相应的数组里，具体如下：

使用的开源库是：LuseenBottomNavigation

本应用《任您记）APP项目中用法是依赖：compile 'com.github.armcha:LuseenBottomNavigation:1.8.2'

主要代码：

if (bottomNavigationView != null) {

bottomNavigationView.isWithText(false);bottomNavigationView.isColoredBackground(true);bottomNavigationView.setTextActiveSize(getResources().getDimension(R.dimen.dp_18));bottomNavigationView.setTextInactiveSize(getResources().getDimension(R.dimen.dp_18));bottomNavigationView.setItemActiveColorWithoutColoredBackground(ContextCompat.getColor(this, R.color.colorPrimary));bottomNavigationView.setFont(Typeface.createFromAsset(getApplicationContext().getAssets(), "fonts/chinese_character.ttf"));}

BottomNavigationItem bottomNavigationItem = new BottomNavigationItem            ("待办", color[0], image[0]);    BottomNavigationItem bottomNavigationItem1 = new BottomNavigationItem            ("日记", color[1], image[1]);    BottomNavigationItem bottomNavigationItem2 = new BottomNavigationItem            ("账单", color[2], image[2]);    BottomNavigationItem bottomNavigationItem3 = new BottomNavigationItem            ("纪念日", color[3], image[3]);    bottomNavigationView.addTab(bottomNavigationItem);    bottomNavigationView.addTab(bottomNavigationItem1);    bottomNavigationView.addTab(bottomNavigationItem2);    bottomNavigationView.addTab(bottomNavigationItem3);    bottomNavigationView.setOnBottomNavigationItemClickListener(this);
