Set an image if Uri is empty

Question

I want to set an image to the Uri if the Uri is empty, this is what I did:

if (imageUri == null)
{
    imageUri = imageUri.parse(String.valueOf(R.drawable.no_image_available));
}

It does not give any error but it doesn't work, is there any other way I can use to achieve this?

I found some solutions in http://stackoverflow.com/questions/6602417/get-the-uri-of-an-image-stored-in-drawable hope it works :) — Rust Fisher, Mar 27 '17 at 08:30
use: `Uri uri = Uri.parse("android.resource://your.package.here/drawable/R.drawable.no_image_available"); imageview.setImageURI(uri);` — rafsanahmad007, Mar 27 '17 at 08:31

Bitmap yourImageNotFoundBitmap = BitmapFactory.decodeResource(context.getResources(),
                                           R.drawable.no_image_available);
if (imageUri == null){

yourImage.setImageBitmap(yourImageNotFoundBitmap);

}

Why not setting the image from resource directly? Bitmaps are costlier for memory. Nice answer, but handling the change directly will make it better – Mohammed Atif Mar 27 '17 at 08:26
@MohammedAtif, how can I achieve that? – Zack Mar 27 '17 at 09:45
`yourImage.setImageResource(R.drawable.no_image_available);` thats it – Mohammed Atif Mar 27 '17 at 09:48
@MohammedAtif, Wow.. amazing, it works fine...Thanks alot – Zack Mar 27 '17 at 09:50

Instead you can use glide library. If imageUrl is there then it will show otherwise it will take placeHolder image.


    Glide.with(context)
            .load(imageUrl)
            .diskCacheStrategy(DiskCacheStrategy.SOURCE)
            .dontTransform()
            .placeholder(placeholder)
            .into(imageView);

Just check that Empty URI is not equal to followUri, this check includes check by null:

 if (!Uri.EMPTY.equals(followUri)) {
        //handle followUri
 }

What do I need to have between the braces? – Zack Mar 27 '17 at 09:47

This :

imageUri = imageUri.parse(String.valueOf(R.drawable.no_image_available));

will not give you a valid Uri.

There is Much more easier option:

option 1

 Uri uri = Uri.parse("android.resource://your.package.here/drawable/R.drawable.no_image_available"); 
imageview.setImageURI(uri);  //set the uri

OR use:

if (imageUri == null)
{
    imageView.setImageResource(R.drawable.no_image_available);
}

Set an image if Uri is empty
