At present, the head navigation of many apps is similar to non-navigation. In order to simplify development and reduce coupling, the encapsulated NavigationBar has been used.

Unified strong menu click event.

code use case

        NavigationBar navBar1 = (NavigationBar) findViewById(R.id.nav_bar_1);
        navBar1.setTitle("Nav1");//中间标题
        navBar1.addFromLeft(NavItems.search_img);//左侧添加可多个
        navBar1.addFromRight(NavItems.search_txt);//右侧添加可多个
        navBar1.setNavgationListener(navgationListener);
        //
        NavigationBar navBar2 = (NavigationBar) findViewById(R.id.nav_bar_2);
        navBar2.setTitle("Nav2");
        navBar2.addFromLeft(NavItems.search_img);//左侧1
        navBar2.addFromLeft(NavItems.save);//左侧2
        navBar2.addFromRight(NavItems.messgae_count_view);//右侧自定义View
        navBar2.setNavgationListener(navgationListener);
        //
        NavigationBar navBar3 = (NavigationBar) findViewById(R.id.nav_bar_3);
        navBar3.setTitle("View Title");
        SearchBar mSearchBar = createSearchBar();//自定义View
        navBar3.replaceTitleView(mSearchBar);//替换到标题位置
        //navBar3.addFromLeft(NavItems.save);//同时支持左右添加
        navBar3.setNavgationListener(navgationListener);

        //-----其他常用函数-----
        //添加整个导航层View
        //navBar3.addTopLayer(mSearchBar);

        //设置title的drawable
        //navBar3.setTitleTextViewDrawable(left,top,right,bottom);

        //使用Layout Id直接替换title
        //navBar3.replaceTitleView(R.layout.xxx);

        //通过res设置title
        //navBar3.setTitle(R.string.app_name);

        //设置item是否可见
        //navBar3.changeNavChildVisiable(itemId,visiable);

menu item monitor

private NavgationListener navgationListener = new NavgationListener() {
        @Override
        public void onNavigationClick(View v, NavItem item, NavigationBar nav) {
            if (item.getId() == NavItems.search_img.getId()) {
                toast("img(Search)");
            } else if (item.getId() == NavItems.search_txt.getId()) {
                toast("txt(Search)");
            } else if (item.getId() == NavItems.messgae_count_view.getId()) {
                toast("view(MsgCount)");
            } else if (item.getId() == NavItems.save.getId()) {
                toast("txt(Save)");
            }
        }
    };

menu item definition

public class NavItems {
    public static final NavItem search_img = BaseNavItem.img(R.drawable.nav_icon_search);
    public static final NavItem search_txt = BaseNavItem.text("Search");
    public static final NavItem save = BaseNavItem.text("Save");
    public static final NavItem messgae_count_view = BaseNavItem.view(R.layout.nav_item_msg_count);
}

Usually, after introducing NavigationBar, you only need to define the Item that the project needs to use.
