Add ViewPagerIndicator to Android Studio

Question

i\'m trying to get Jake Wharton\'s ViewPagerIndicator working with Android Studio but unfortunately it won\'t work.
I downloaded the .aar file from here and included it

Answer 1

You can do it without any third party library

Final Result:

1) Use frame layout as a container for Viewpager and then add a Linearlayout at the bottom of it.

2) Define size and margin for indicators

  //define globaly 
   private LinearLayout.LayoutParams imageParam;

   //init params
      int margin = Utils.pxFromDp(getActivity(), 5);
        int width = Utils.pxFromDp(getActivity(), 8);
        imageParam = new LinearLayout.LayoutParams(width, width);
        imageParam.setMargins(margin, margin, margin, margin);

3) Add Indicators in Linear Layout

 for (int indicatorCount = 0; indicatorCount < productFromShoppingList.getProductImages().size();
             indicatorCount++) {

            ImageView imageIndicator =
                    new ImageView(getActivity());

            imageIndicator.setAdjustViewBounds(true);
            imageIndicator.setScaleType(ImageView.ScaleType.FIT_XY);
            imageIndicator.setLayoutParams(imageParam);

            indicatorContainer.addView(imageIndicator);
            indicators.add(imageIndicator);
            imageIndicator.setBackgroundResource(R.drawable.indicator_unselected);
        }

4) Initialize indicator at 0 position

 indicators.get(0).setBackgroundResource(R.drawable.indicator_unselected);

5) Update indicator on view pager page change

carousalViewPager.setAdapter(new slidingPagerAdapter(getActivity(),
            productFromShoppingList.getProductImages()));

    carousalViewPager
            .addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
                @Override
                public void onPageScrolled(int position,
                                           float positionOffset, int positionOffsetPixels) {

                }

                @Override
                public void onPageSelected(int position) {

                    currentPageIndex = position;
                    updateIndicators(currentPageIndex);
                }

                @Override
                public void onPageScrollStateChanged(int state) {

                }
            });


private void updateIndicators(int selectedPostion) {
    for (int indicatorPosition = 0; indicatorPosition < indicators.size(); indicatorPosition++) {
        indicators.get(indicatorPosition).setBackgroundResource(indicatorPosition == selectedPostion ? R.drawable.indicator_selected
                : R.drawable.indicator_unselected);
    }
}

Last but not least add this 2 drawable for indicator

indicator_unselected.xml

indicator_selected.xml
