load images from url and load into ViewPager with json in android

STEP 1: viewpager xml file  

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

STEP 2: ViewPagerAdapter class

public class ViewPagerAdapter extends PagerAdapter {     Context c;     private List<String> _imagePaths;     private LayoutInflater inflater;     public ViewPagerAdapter (Context c, List<String> imagePaths) {         this._imagePaths = imagePaths;         this.c = c;     }     @Override    public int getCount() {         return this._imagePaths.size();     }     @Override    public boolean isViewFromObject(View view, Object object) {         return view == (object);     }     @Override    public Object instantiateItem(ViewGroup container, int position) {         ImageView imgDisplay;         inflater = (LayoutInflater)c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);         View viewLayout = inflater.inflate(R.layout.product_viewpager_image, container,                 false);         imgDisplay = (ImageView) viewLayout.findViewById(R.id.image);         Glide.with(c).load(_imagePaths.get(position)).         placeholder(R.drawable.about).error(R.drawable.about).into(imgDisplay);         (container).addView(viewLayout);         return viewLayout;     }     @Override      public void destroyItem(ViewGroup container, int position, Object object) {         (container).removeView((RelativeLayout) object);     } }

STEP3:main activity code:

List<String> images=new ArrayList<>(); ViewPager viewpager = (ViewPager) findViewById(R.id.pager); images.add("imageurl"); images.add("imageurl"); images.add("imageurl"); images.add("imageurl"); ViewPagerAdapter adapter = new ViewPagerAdapter (MainActivity.this, images); viewpager.setAdapter(adapter);
