Example

Style

With ViewPager

Add ViewBadger

Adding to project

Dependency

compileSdkVersion >= 25 and add design :

compile 'com.android.support:design:25.0.1'

Importing to project

Example for Gradle:

Step 1. Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the dependency

compile 'com.github.ittianyu:BottomNavigationViewEx:1.1.1'

and for Maven:

Step 1. Add it in your root build.gradle at the end of repositories:

<repositories>
	<repository>
	    <id>jitpack.io</id>
	    <url>https://jitpack.io</url>
	</repository>
</repositories>

Step 2. Add the dependency

<dependency>
    <groupId>com.github.ittianyu</groupId>
    <artifactId>BottomNavigationViewEx</artifactId>
    <version>1.1.1</version>
</dependency>

Manual:

Downloading BottomNavigationViewEx.java and copying it to you project。

Getting started

Adding a custom widget in xml :

<com.ittianyu.bottomnavigationviewex.BottomNavigationViewEx
    android:id="@+id/bnve"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    app:itemBackground="@color/colorPrimary"
    app:itemIconTint="@color/selector_item_color"
    app:itemTextColor="@color/selector_item_color"
    app:menu="@menu/menu_navigation_with_view_pager" />

Binding view in Activity:

BottomNavigationViewEx bnve = (BottomNavigationViewEx) findViewById(R.id.bnve);

Disable all animations

bnve.enableAnimation(false);
bnve.enableShiftingMode(false);
bnve.enableItemShiftingMode(false);

Binding with ViewPager

// set adapter
adapter = new VpAdapter(getSupportFragmentManager(), fragments);
bind.vp.setAdapter(adapter);

// binding with ViewPager
bind.bnve.setupWithViewPager(bind.vp);

Other usage in BottomNavigationViewEx

You can see the demo.

Usage in BottomNavigationView

Other usage is the same as official BottomNavigationView. You can click here for detail.

References

The lib is based on BottomNavigationView in Support Library 25 design.

I found it was inflexible when I try in demo. For example, I can't change the current checked item by code. So I write a class extends it to provide some useful method.

You no need to worry about stability. Because I minimise modifying by reflecting.

加入工程

依赖

compileSdkVersion >= 25 且添加 design 依赖包:

compile 'com.android.support:design:25.0.1'

导入本库

Gradle例子:

步骤 1. 在工程根目录的 build.gradle 最后添加如下代码:

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

步骤 2. 添加依赖

compile 'com.github.ittianyu:BottomNavigationViewEx:1.1.1'

Maven例子:

步骤 1. 在工程根目录的 build.gradle 最后添加如下代码:

<repositories>
	<repository>
	    <id>jitpack.io</id>
	    <url>https://jitpack.io</url>
	</repository>
</repositories>

步骤 2. 添加依赖

<dependency>
    <groupId>com.github.ittianyu</groupId>
    <artifactId>BottomNavigationViewEx</artifactId>
    <version>1.1.1</version>
</dependency>

手动导入:

下载文件 BottomNavigationViewEx.java 并复制到你的工程中。

开始使用

在 xml 布局中添加自定义控件:

<com.ittianyu.bottomnavigationviewex.BottomNavigationViewEx
    android:id="@+id/bnve"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    app:itemBackground="@color/colorPrimary"
    app:itemIconTint="@color/selector_item_color"
    app:itemTextColor="@color/selector_item_color"
    app:menu="@menu/menu_navigation_with_view_pager" />

在 Activity 中绑定控件:

BottomNavigationViewEx bnve = (BottomNavigationViewEx) findViewById(R.id.bnve);

禁止所有动画效果

bnve.enableAnimation(false);
bnve.enableShiftingMode(false);
bnve.enableItemShiftingMode(false);

和 ViewPager 绑定####

// set adapter
adapter = new VpAdapter(getSupportFragmentManager(), fragments);
bind.vp.setAdapter(adapter);

// binding with ViewPager
bind.bnve.setupWithViewPager(bind.vp);

其他 BottomNavigationViewEx 的用法

请参考demo。

其他 BottomNavigationView 的用法

其他用法和官方 BottomNavigationView 一样。 详情点击这里

来源

本库修改自安卓官方 Support Library 25 design 中的 BottomNavigationView。

我在尝试使用官方的库时，发现缺少灵活性。比如官方并没有提供切换当前选中项的方法。所以我在此基础上包装了一层，对外公开了一些方法。

你完全没有必要担心库的稳定性，因为我是使用反射对父类进行最小限度的修改。
