# BottomNavigationBar

Material design 更新的BottomNavigationbar的开源实现



目前版本最新版本是v0.3，还在努力完善中，有兴趣的朋友可以关注。如果发现问题请写在issue，我会定期查看和修复。



###version



v0.1 基础版本



v0.2 支持修改tab selected 情况下的width scale 属性



v0.3 支持设置tab text 在unselected情况下是否隐藏



###Demo修改

有童鞋反应说要如何实现像新规范里面NavigationBar透明的样式，所以这里把项目的Demo修改一下，实现Navigationbar透明并且覆盖在BottomNavigationBar上面。（目前这种实现方式还不够完善，会导致statusBar也不占位的问题。如果有网友有更好的实现方式，不妨提出来，大家一起探讨和分享。）

ps:最近碰上公司项目比较赶，所以暂停了BottomNavigationBar的开源进度。



具体实现：

demo基础上



        setContentView(R.layout.activity_main);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

            Window window = getWindow();

            // Translucent status bar

            window.setFlags(

                    WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,

                    WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

            // Translucent navigation bar

            window.setFlags(

                    WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION,

                    WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);

        }

去掉所有的xml中的所有android:fitsSystemWindows="true"

####How to use

[![](https://jitpack.io/v/RoyWallace/BottomNavigationBar.svg)](https://jitpack.io/#RoyWallace/BottomNavigationBar)



**Step 1**. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:



    allprojects {

        repositories {

            ...

            maven { url "https://jitpack.io" }

        }

    }

**Step 2.** Add the dependency



    dependencies {

            compile 'com.github.RoyWallace:BottomNavigationBar:v0.1'

    }



**Step 3.**  use it in your layout xml



    

**Step 4.** add tab and tabSelected listener



    bottomLayout = (BottomNavigationBar) findViewById(R.id.bottomLayout);

    //params: int icon,String text,int color

    bottomLayout.addTab(R.mipmap.ic_local_movies_white_48dp, "Movies & Tv", 0xff4a5965);

    bottomLayout.setOnTabListener(new BottomNavigationBar.TabListener() {

        @Override

        public void onSelected(int position) {

            //...

        }

    });

and you can also use the **BottomNavigationBehavior** with **CoordinatorLayout** 



    



####Set tab selected width( bottomLayout.setTabWidthSelectedScale(1.5f);

####Set tab text default visible

    bottomLayout.setTextDefaultVisible(true);
