How To Fetch Images On Viewpager From Server

I want to implement one app for image showing where images will come from server side and there will be maximum 4 images suppose that there are only one or two image on server then

Solution 1:

You need to check if other URLs are blank then you don't need to add into Array of Image. Change your code with below code and check.

 String[] IMAGES={p0,p1,p2,p3};
 for(int i=0;i<IMAGES.length;i++) {
      if(!IMAGES[i].isEmpty()) {
           ImagesArray.add(IMAGES[i]);
      }
      if (p0.equalsIgnoreCase("https://www.maangal.com/photos/large_"))
      {
            Log.e("pic**********", url1 + IMAGES[i]);
            mPager.setVisibility(View.GONE);
       }
  }

Solution 2:

I have done it, if there is images then the array will ImagesArray.add(url1 + IMAGES[i]); and if there is no images nothing will add on arrayList

String[] IMAGES = {p0, p1, p2, p3};
    for (int i = 0; i < IMAGES.length; i++) {
        if (IMAGES[i].equalsIgnoreCase("") || IMAGES[i].equalsIgnoreCase("nophoto.jpg") || IMAGES[i].equalsIgnoreCase("https://www.maangal.com/photos/large_")) {
            Log.e("piccc-----------", IMAGES[i]);
        } else {
            ImagesArray.add(url1 + IMAGES[i]);
            Log.e("else", url1 + IMAGES[i]);
        }
    }
