    To show slides of images, we use ViewPager in android that provided by the support library.

    First of all add images that we want to show in drawable folder.

    Then create array of these images.

      private int[] mResources = {
                R.drawable.slide_1,
                R.drawable.slide_2,
                R.drawable.slide_3,
                R.drawable.slide_4,
                R.drawable.slide_5,
    
        };


    in xml file create viewpager like this

     <android.support.v4.view.ViewPager
                android:id="@+id/pager"
    
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                >
    
            </android.support.v4.view.ViewPager>


    Then in Java, initialize the ViewPager and create Adapter to set on it.
     

    mViewPager = (ViewPager) rootView.findViewById(R.id.pager);
    ImagePagerAdapter mImagePagerAdapter;
    mImagePagerAdapter = new ImagePagerAdapter(this);
    mViewPager.setAdapter(mImagePagerAdapter);
    
       class ImagePagerAdapter extends PagerAdapter {
    
            Context mContext;
            LayoutInflater mLayoutInflater;
    
            public ImagePagerAdapter(Context context) {
                mContext = context;
                mLayoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            }
    
            @Override
            public int getCount() {
                return mResources.length;
            }
    
            @Override
            public boolean isViewFromObject(View view, Object object) {
                return view == ((LinearLayout) object);
            }
    
            @Override
            public Object instantiateItem(ViewGroup container, int position) {
                View itemView = mLayoutInflater.inflate(R.layout.pager_item, container, false);
    
                ImageView imageView = (ImageView) itemView.findViewById(R.id.imageView);
                imageView.setImageResource(mResources[position]);
    
    
                container.addView(itemView);
                return itemView;
            }
    
            @Override
            public void destroyItem(ViewGroup container, int position, Object object) {
                container.removeView((LinearLayout) object);
            }
        }
