Android底部导航栏之BottomNavigationBar

  • 参考:
    五种方式实现Android底部导航栏
    BottomNavigation(官方)
    BottomNavigationBar的使用

一. BottomNavgationBar简介

  • 鉴于官方BottomNavigationView还不是很完善,在此就先使用大佬们做的第三方库
  • 本文讲的是Ashok-Varma的BottomNavigation
  • 先看效果:
Android底部导航栏之BottomNavigationBar_第1张图片
效果图
  • 特性:
  • 定制丰富的导航栏.
  • 遵循Google的底部导航规范
  • 每个Tab的模式可以选择,每个Tab可以有自己的颜色.
  • 自定义图标

二. 用法

2.1几个重要的设置方法

  • /*设置背景颜色*/ setBarBackgroundColor()//参数为R.id.color或者RGB颜色值(String形式)
    该方法在BackgroundStyle为BottomNavigationBar.BACKGROUND_STYLE_STATIC的时候才生效

  • /*设置背景模式*/ setBackgroundStyle()
    该方法参数有三种(效果图会配合TabMode一起展示)

  • BottomNavigationBar.BACKGROUND_STYLE_STATIC //静态背景

  • BottomNavigationBar.BACKGROUND_STYLE_RIPPLE//点击之后会扩散的背景

  • BottomNavigationBar.BACKGROUND_STYLE_DEFAULT//和RIPPLE好像一样

  • /*设置Tab点击的模式*/ setMode()
    该方法参数也有三种

  • BottomNavigationBar.MODE_FIXED //自适应长度的Tab(Tab会均匀分布在整个长度内),Tab的文字默认显示

  • BottomNavigationBar.MODE_SHIFTING //点击之后会自己弹出来(Tab的文字默认不显示,点击之后才会显示)

  • BottomNavigationBar.MODE_DEFAULT //和SHIFTING一样

  • /*为导航栏添加Tab*/ addItem()
    该方法参数为BottomNavigationItem对象
    BottomNavigationItem的常用方法有:

/*构造函数(参数为当前Tab的图标和标题)*/
BottomNavigationItem(@DrawableRes int mIconResource, @NonNull String mTitle)
BottomNavigationItem(Drawable mIcon, @NonNull String mTitle)
BottomNavigationItem(Drawable mIcon, @StringRes int mTitleResource)
BottomNavigationItem(@DrawableRes int mIconResource, @StringRes int mTitleResource)
/*设置点击状态的Icon*/
setActiveIcon(Drawable mActiveIcon)(参数为drawable资源)
setActiveIconResource(@DrawableRes int mActiveIconResource) (参数为drawableId)
/*设置点击状态的Color*/
setActiveColor(int color)(参数为colorId)
setActiveColor(@Nullable String colorCode)(参数为String形式的RGB颜色值)
setActiveColorResource(@ColorRes int colorResource)(参数为colorResource)
/*设置未点击状态的Icon*/
setInactiveIcon(Drawable mInactiveIcon)(参数为drawable资源)
setInactiveIconResource(@DrawableRes int mInactiveIconResource) (参数为drawableId)
/*设置未点击状态的Color*/
setInActiveColor(int color)(参数为colorId)
setInActiveColor(@Nullable String colorCode)(参数为String形式的RGB颜色值)
setInActiveColorResource(@ColorRes int colorResource)(参数为colorResource)
  • setFirstSelectedPosition(0) //设置默认选中的Tab
  • initialise() //初始化(初始化之后才代表完成设置)

2.2效果图(点击之后的颜色效果在addItem()方法里面设置)

  • Default默认效果


    Default默认效果
  • FIXED+STATIC


    FIXED+STATIC
  • FIXED+RIPPLE


    FIXED+RIPPLE
  • SHIFTING+RIPPLE


    SHIFTING+RIPPLE

2.3使用步骤

  • 在build.gradle里面添加
compile 'com.ashokvarma.android:bottom-navigation-bar:1.4.1'//版本号可能会更新,以具体更新为准
  • xml中使用控件


  • 样式配置
/*1.首先进行fvb*/
bottomNavigationBar = (BottomNavigationBar) findViewById(R.id.bottom_nav_bar);
/*2.进行必要的设置*/
bottomNavigationBar.setBarBackgroundColor(R.color.colorPrimary);
bottomNavigationBar.setBackgroundStyle(BottomNavigationBar.BACKGROUND_STYLE_RIPPLE);
bottomNavigationBar.setMode(BottomNavigationBar.MODE_SHIFTING);//适应大小
/*3.添加Tab*/
bottomNavigationBar.addItem(new BottomNavigationItem(
        R.drawable.listen_fill,R.string.bottom_nav_home)
        .setInactiveIconResource(R.drawable.listen)
        .setActiveColorResource(R.color.colorPrimary))
        .addItem(new BottomNavigationItem(
                R.drawable.speech_fill,R.string.bottom_nav_like)
                .setInactiveIconResource(R.drawable.speech)
                .setActiveColorResource(R.color.colorPrimaryDark))
                .addItem(new BottomNavigationItem(
                 R.drawable.social_fill,R.string.bottom_nav_location)
                .setInactiveIconResource(R.drawable.social)
                .setActiveColorResource(R.color.yellow))
                .addItem(new BottomNavigationItem(
                 R.drawable.profile_fill,R.string.bottom_nav_person)
                .setInactiveIconResource(R.drawable.profile)
                .setActiveColorResource(R.color.colorAccent))
                .setFirstSelectedPosition(0)//默认显示面板
                .initialise();//初始化
  • PS:当Background为BACKGROUND_STYLE_RIPPLE的时候,背景颜色设置会无效,这时背景颜色会体现在setActiveColor()的设置上面*
  • 监听器配置
  • 实现BottomNavigationBar.OnTabSelectedListener接口
  • 重载方法
    /*Tab被选中(position为当前被选中的Tab)*/
   @Override
    public void onTabSelected(int position) {

    }
    /*Tab被取消选中(position为当前被选中的Tab)*/
    @Override
    public void onTabUnselected(int position) {

    }
    /*Tab被重新选中(position为当前被选中的Tab)*/
    @Override
    public void onTabReselected(int position) {

    }
  • 重载方法里实现需要的逻辑(一般就是开启transaction进行fragment的切换)

三. 源码

  • xml


    
    
    

  • MainActivity

                .setFirstSelectedPosition(0)//默认显示面板
                .initialise();//初始化
    }

    private void initTab(){
