• [x] Implements the red mark on the TabBar, and can drag

• [x] Reference annotation method, construction TabBarItem

Usage:

1.Introducing Gradle dependency

repositories {
        jcenter()
    }

    dependencies{
        compile 'com.jpeng:JPTabBar:1.2.3'
    }

2.Add JPTabBar to your main interface layout

3.In your main interface using an array of variables to declare an array of variables, the internal reflection to generate TabItem, attention is:NorIcons are required, the length of each array should be consistent

@Titles
    private static final String[] mTitles = {"页面一","页面二","页面三","页面四"};

    @SeleIcons
    private static final int[] mSeleIcons = {R.mipmap.tab1_selected,R.mipmap.tab2_selected,R.mipmap.tab3_selected,R.mipmap.tab4_selected};

    @NorIcons
    private static final int[] mNormalIcons = {R.mipmap.tab1_normal, R.mipmap.tab2_normal, R.mipmap.tab3_normal, R.mipmap.tab4_normal};

Or, you can init in the oncreate

mTabbar.setTitles(R.string.tab1, R.string.tab2, R.string.tab3, R.string.tab4)
                .setNormalIcons(R.mipmap.tab1_normal, R.mipmap.tab2_normal, R.mipmap.tab3_normal, R.mipmap.tab4_normal)
                .setSelectedIcons(R.mipmap.tab1_selected, R.mipmap.tab2_selected, R.mipmap.tab3_selected, R.mipmap.tab4_selected)
                .generate();

After above, the layout of the TabBar basically has been built. If you want to achieve Wechat kind of gradual change as there are automatically ViewPager to change the function of the page, only in the oncreate Activity method, adding a line of code:(Of curse,If you don't use ViewPager,You needn't use this method)

//The parameters must be extends ViewPager
    mTabbar.setContainer(mPager);

In addition, if you want to achieve the effect of the highlight button, you need to add the following code in the current widget of the XML, you can use getMiddleView method to get the view you custom in attribute.

jp:TabMiddleView="@layout/你自定义的 layout"

Method and node description: The Main Method Of JPTabBar:

/**
     * Set custom Tab toggle animation
     */
    public void setCustomAnimate(Animatable customAnimate);


     /**
     * Show the BadgeView With Text
     * default is false ,cannot drag
     */
    public void showBadge(int position,String text);

    /**
     * It is the same with the up method,But the different is,
     * The Badge Can draggable when you use true.
     */
    public void showBadge(int position,String text,boolean draggable);

    /**
     * set the icon and title filter when scroll page and click the tab
     * default value is false
     */
    public JPTabBar setUseFilter(boolean filter);

    /**
     * Set the boolean If Need the PageAnimate
     * default value is false
     */
    public JPTabBar setUseScrollAnimate(boolean scrollAnimate);

    /**
      *Show the Circle point
      */ 
    public void showCircleBadge(int pos);

    /**
      * Set the Badge Message Count Limit
      * If you use ShowBadge(int position,int count)
      * If the Second parameters > limit , it will show "limit+"
      * you can see the screenshots
      */
    public void setCountLimit(int limit);

    /**
     * Hide the OVAL Badge
     */
    public void hideBadge(int position);

    /**
     * Switch Tab page
     */
    public void setSelectTab(int index);

    /**
     * Set the Observer of the Click Tab Event
     */
    public void setTabListener(OnTabSelectListener listener);

    /**
     * set the CallBack of the Badge Dragging Dismiss
     */
    public void setDismissListener(BadgeDismissListener listener);

     /**
      * get the TabMiddleItem View that you set in "TabMiddleView" attribute
     */
    public View getMiddleView();

1.If you have given setContainer TabBar, do not setOnPageChangeListener to ViewPager

/**
    *If you already have the TabBar set up the container, 
    *and then call this method,
    *the kind of WeChat that drag the gradient effect and automatically switch the page will be invalid
    *If you want to listen to the page to change the event, you can use the TabListener
   */
  mPager.setOnPageChangeListener(this);

2.If you want to achieve the middle of the button, you parent ViewGroup must be RelativeLayout or FrameLayout,because the TabBar Add MiddleIcon into it is depend on the parent Layout

3.If you want to Disable the scroll of ViewPager,you can use NoScrollViewPager in my demo
