Bottom navigation，有两种Mode：分别是Fixed、Shifting
Fixed：
Shifting：
1.依赖：
compile ‘com.ashokvarma.android:bottom-navigation-bar:1.4.1‘
2.布局文件：
<com.ashokvarma.bottomnavigation.BottomNavigationBar android:id="@+id/bottom_navigation_bar" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="bottom"/> <!--app:bnbAutoHideEnabled="false"/>-->
3、Activity中的实现，注意的参数
1.设置导航栏模式：setMode（）
Attribute: mode_fixed, mode_shifting,mode_default
Method: setMode() Values：MODE_FIXED, MODE_SHIFTING
.setMode(BottomNavigationBar.MODE_FIXED)；
2.设置导航栏背景模式：setBackgroundStyle（）
Attribute: background_style_static, background_style_ripple,background_style_default
Method:setBackgroundStyle（）Values：BACKGROUND_STYLE_STATIC, BACKGROUND_STYLE_RIPPLE
.setBackgroundStyle(BottomNavigationBar.BACKGROUND_STYLE_RIPPLE)
3.设置BottomNavigationItem颜色
Attributes: bnbActiveColor, bnbInactiveColor, bnbBackgroundColor Value: Color value or resource
Methods: setActiveColor, setInActiveColor, setBarBackgroundColor Value: Color value or resource
BottomNavigationItem
.setActiveColorResource(R.color.primary)
4.添加标记BadgeItem
BadgeItem numberBadgeItem = new BadgeItem() .setBorderWidth(4) .setBackgroundColorResource(R.color.blue) .setText("5") .setHideOnSelect(autoHide.isChecked()); // TODO 控制便签消失或不消失 bottomNavigationBar .addItem(new BottomNavigationItem(R.drawable.ic_home_white_24dp, "Home").setActiveColorResource(R.color.orange).setBadgeItem(numberBadgeItem))
// TODO 设置 BadgeItem 默认隐藏 注意 这句代码在添加 BottomNavigationItem 之后
numberBadgeItem.hide();
5.设置事件监听器TabChangeListener
bottomNavigationBar.setTabSelectedListener(new BottomNavigationBar.OnTabSelectedListener(){ @Override public void onTabSelected(int position) { } @Override public void onTabUnselected(int position) {] } @Override public void onTabReselected(int position) { } });
展示
MODE_FIXED+BACKGROUND_STYLE_STATIC效果
DE_FIXED+BACKGROUND_STYLE_RIPPLE效果
MODE_SHIFTING+BACKGROUND_STYLE_STATIC效果
MODE_SHIFTING+BACKGROUND_STYLE_RIPPLE效果
JAVA
public class MainActivity extends AppCompatActivity implements BottomNavigationBar.OnTabSelectedListener { @BindView(R.id.bottom_navigation_bar) BottomNavigationBar mBottomNavigationBar; @BindView(R.id.fragment_container) FrameLayout mFrameLayout; private BookFragment mBookFragment; private LikeFragment mLikeFragment; private UserFragment mUserFragment; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ButterKnife.bind(this); InitNavigationBar(); } private void InitNavigationBar() { mBottomNavigationBar.setTabSelectedListener(this); mBottomNavigationBar.setMode(BottomNavigationBar.MODE_FIXED); mBottomNavigationBar.setBackgroundStyle(BottomNavigationBar.BACKGROUND_STYLE_RIPPLE); mBottomNavigationBar .addItem(new BottomNavigationItem(R.drawable.literature_100, "图书").setActiveColorResource(R.color.orange)) .addItem(new BottomNavigationItem(R.drawable.like_100, "收藏").setActiveColorResource(R.color.teal)) .addItem(new BottomNavigationItem(R.drawable.user_100, "设置").setActiveColorResource(R.color.blue)) .setFirstSelectedPosition(0) .initialise(); } /** * 设置默认的 */ private void setDefaultFragment() { FragmentManager fm = getSupportFragmentManager(); FragmentTransaction transaction = fm.beginTransaction(); mBookFragment = BookFragment.newInstance(); transaction.replace(R.id.fragment_container, mBookFragment); transaction.commit(); } @Override public void onTabSelected(int position) { Log.d("onTabSelected", "onTabSelected: " + position); FragmentManager fm = getSupportFragmentManager(); FragmentTransaction transaction = fm.beginTransaction(); switch (position) { case 0: if (mBookFragment == null) { mBookFragment = BookFragment.newInstance(); } transaction.replace(R.id.fragment_container, mBookFragment); break; case 1: if (mLikeFragment == null) { mLikeFragment = LikeFragment.newInstance(); } transaction.replace(R.id.fragment_container, mLikeFragment); break; case 2: if (mUserFragment == null) { mUserFragment = UserFragment.newInstance(); } transaction.replace(R.id.fragment_container, mUserFragment); break; default: break; } // 事务提交 transaction.commit(); } @Override public void onTabUnselected(int position) { Log.d("onTabUnselected", "onTabUnselected: " + position); } @Override public void onTabReselected(int position) { Log.d("onTabReselected", "onTabReselected: " + position); } }
