### Manual

Add `TabBubbleAnimator` content of res package to your project

## Usage

Add TabLayout to your xml

<com.cuberto.bubbleicontabbarohos.TabLayoutv2
    ohos:id="$+id:tablayout"
    ohos:weight ="1"
    ohos:height="match_content"
    ohos:width="match_content">

</com.cuberto.bubbleicontabbarohos.TabLayoutv2>

Create adapter in your AbilitySlice, add some Component and set PageSlider adapter

TabLayoutv2 tabLayout;
private String[] titles = new String[]{"Home", "Clock", "Folder", "Menu"};
private int[] colors = new int[]{ResourceTable.Color_home, ResourceTable.Color_clock, ResourceTable.Color_folder, ResourceTable.Color_menu};
private Context context;
private ComponentContainer rootLayout;
private PageSlider mPager;
private PageViewAdapter pageViewAdapter;
private TabBubbleAnimator tabBubbleAnimator;
private List<PageInfo> mPageViews;

@Override
protected void onStart(Intent intent) {

    super.onStart(intent);
    rootLayout = (ComponentContainer)LayoutScatter.getInstance(this)
            .parse(ResourceTable.Layout_ability_main, null, false);

    tabLayout = (TabLayoutv2)rootLayout.findComponentById(ResourceTable.Id_tablayout);
    mPager = (PageSlider) ResUtil.findComponentById(rootLayout, ResourceTable.Id_slider).get();

    mPageViews = new ArrayList();
    mPageViews.add(new TabComponent(this, titles[0], colors[0]));
    mPageViews.add(new TabComponent(this, titles[1], colors[1]));
    mPageViews.add(new TabComponent(this, titles[2], colors[2]));
    mPageViews.add(new TabComponent(this, titles[3], colors[3]));

    pageViewAdapter = new PageViewAdapter(this, mPageViews);
    mPager.setProvider(pageViewAdapter);
}

Setup your TabLayout with ViewPager

    tabLayout = (TabLayoutv2)rootLayout.findComponentById(ResourceTable.Id_tablayout);
    tabLayout.setupWithPageSlider( mPager);

Create TabBubbleAnimator and tabItem as title, image id and color for each fragment

    tabBubbleAnimator = new TabBubbleAnimator(tabLayout);
    tabBubbleAnimator.addTabItem(titles[0], ResourceTable.Graphic_ic_grid, colors[0]);
    tabBubbleAnimator.addTabItem(titles[1], ResourceTable.Graphic_ic_clock,colors[1]);
    tabBubbleAnimator.addTabItem(titles[2], ResourceTable.Graphic_ic_folder, colors[2]);
    tabBubbleAnimator.addTabItem(titles[3], ResourceTable.Graphic_ic_menu, colors[3]);

Call highlightTab() for 0 position and add tabBubbleAnimator as OnPageChangeListener to ViewPager

    tabBubbleAnimator.highLightTab(0);
    mPager.addPageChangedListener( tabBubbleAnimator);
