Picasso only loading one image

So I've checked the size of "parsedPhotoStrings" and it's clearly greater than 1. However, only one image is displayed with the following code. I'm not sure what is going on. 

for (int i = 0; i < parsedPhotoStrings.size(); i++) {
                    String photoUrl = createPlacePhotosUrl(parsedPhotoStrings.get(i));
                    ImageView imageView = new ImageView(MarkerActivity.this);
                    Picasso.with(MarkerActivity.this).load(photoUrl).resize(width, 0).into(imageView);
                    photoLayout.addView(imageView);
                }

EDIT:

Multiple photos are showing! I overlooked my orientation of the layout. However, the cache is still not clearing even after .netWorkPolicy(NetWorkPolicy_CLEAR_CACHE) and .memoryPolicy(MemoryPolicy.CLEAR_CACHE)

EDIT:

for (int i = 0; i < parsedPhotoStrings.size(); i++) {
                String photoUrl = createPlacePhotosUrl(parsedPhotoStrings.get(i));
                ImageView imageView = new ImageView(MarkerActivity.this);
                photoLayout.addView(imageView);
                Picasso.with(MarkerActivity.this).load(photoUrl)
                        .networkPolicy(NetworkPolicy.NO_CACHE, NetworkPolicy.NO_STORE)
                        .memoryPolicy(MemoryPolicy.NO_CACHE, MemoryPolicy.NO_STORE)
                        .resize(width, 0)
                        .into(imageView);
                imageView.setImageResource(0);
                imageView.setImageDrawable(null);
                Picasso.with(MarkerActivity.this).invalidate(photoUrl);
            }

I've tried so many things to clear the cache. Still got nothing working. Any help is appreciated!

It is due to caching. You have to implement this:-

Picasso.with(YourActivity.this)                                            
.load(childjson.getString("your_string"))
.networkPolicy(NetworkPolicy.NO_CACHE)
.memoryPolicy(MemoryPolicy.NO_CACHE)
.skipMemoryCache()
.into(yourImagePreview);

And just make sure to change dependency of picasso in build.gradle with:-

compile "com.squareup.picasso:picasso:2.5.2"

This will support no memory caching. Happy Coding!

First check if the image is caching ht eurl,if so add the code to invalidate() the url.This wil remove previous cache.

Picasso.with(this).invalidate(url);

Second check for the network cachcing mechanism.This code will make no caching for the images

Picasso.networkPolicy(NetworkUtils.isConnected(this) ?
                        NetworkPolicy.NO_CACHE : NetworkPolicy.OFFLINE)

So you code should be like

for (int i = 0; i < parsedPhotoStrings.size(); i++) {
        String photoUrl =createPlacePhotosUrl(parsedPhotoStrings.get(i));
        Picasso.with(this).invalidate(url);

        ImageView imageView = new ImageView(MarkerActivity.this);
        photoLayout.addView(imageView);

        Picasso.with(MarkerActivity.this)
                .load(photoUrl)
                .networkPolicy(NetworkUtils.isConnected(this) ?
                        NetworkPolicy.NO_CACHE : NetworkPolicy.OFFLINE)
                .memoryPolicy(MemoryPolicy.NO_CACHE); 
                .resize(width, 0)
                .into(imageView);
}

Also to support these code you need picasso version 2.5.+

compile 'com.squareup.picasso:picasso:2.5.2'

try this use .memoryPolicy(MemoryPolicy.NO_CACHE)

Picasso.with(MarkerActivity.this).load(photoUrl).resize(width, 0).memoryPolicy(MemoryPolicy.NO_CACHE).into(imageView);

sample code

for (int i = 0; i < parsedPhotoStrings.size(); i++) {
   String photoUrl = createPlacePhotosUrl(parsedPhotoStrings.get(i));
   ImageView imageView = new ImageView(MarkerActivity.this);
   photoLayout.addView(imageView);
   Picasso.with(MarkerActivity.this).load(photoUrl).resize(width, 0).memoryPolicy(MemoryPolicy.NO_CACHE).into(imageView);

 }

Just reverse the order.

Add the ImageView then load image:

Change this to

for (int i = 0; i < parsedPhotoStrings.size(); i++) {
    String photoUrl = createPlacePhotosUrl(parsedPhotoStrings.get(i));
    ImageView imageView = new ImageView(MarkerActivity.this);
    Picasso.with(MarkerActivity.this).load(photoUrl).resize(width, 0).into(imageView);
    photoLayout.addView(imageView);
}

This 

for (int i = 0; i < parsedPhotoStrings.size(); i++) {
    String photoUrl = createPlacePhotosUrl(parsedPhotoStrings.get(i));
    ImageView imageView = new ImageView(MarkerActivity.this);
    photoLayout.addView(imageView);                    
    Picasso.with(MarkerActivity.this).load(photoUrl).memoryPolicy(MemoryPolicy.NO_CACHE).networkPolicy(NetworkPolicy.NO_CACHE).resize(width, 0).into(imageView);
}
