Main functions and features:

  • More Animation effects of multiple Tab switching

  • Implements the effect of the middle button of the bottom navigation

  • Implements like Wechat icon filter and provide animation change.

  • Implements the red mark on the TabBar, and can drag

  • Provide listening to the click event, middle click and badge is dragged away the interface

  • Reference annotation method, construction TabBarItem




1.Introducing Gradle dependency

    repositories {

        compile 'com.jpeng:JPTabBar:1.4.0'

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

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

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

    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)

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

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.


Protruding button:

1.if you want to achieve the effect of a raised button, you first need to append the following node attribute to the XML control of layout, which represents your custom tabbar button layout

    jp:TabMiddleView="@layout/..." Java , you can get layout objects by the getMiddleView method, and you can optionally set the monitor for the layout inside the layout

    View middleView = mJPTabBar.getMiddleView();

3.make sure that the tabbar parent control uses RelativeLayout or FrameLayout as the root node because the highlighted button is added to the parent layout

  <?xml version="1.0" encoding="utf-8"?>
  <!--Use RelativeLayout or FrameLayout --!>
    <!--TabBar --!>

Method and node description:

The Main Method Of JPTabBar:

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

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

       * get if the badge  showing
    public boolean isBadgeShow(int index) 

     * 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();
      * set TabItem title
    public void setTitle(int pos, String title)
      * get TabItem
    public JPTabItem getTabAtPosition(int pos)

Matters needing attention

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

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

3.The callback method of onInterruptSelect in OnTabSelectListener only interrupts the case of clicking on TabItem, and does not consider the page slide past and selected.

The existence problem:

1.About badge function can not drag, drag, disappear and so on, this problem occurred in a part of millet mobile phone model, the original author is Through the suspension window to achieve the explosive effect of badges, such mobile phones by default does not open the suspension window permissions 2.Flip animation failure problem, because HUAWEI Part 7 mobile phones do not support setRotationY and setRotationX,The Flip animation is called setRotationY
