I have used your code to show local images with ZGrid, inside a onclick listener

Hi,

I was looking to load an arraylist of uris with glide but found that in the source file HorizontalListAdapters

Glide.with(this.activity).load((String)this.images.get(position)).into(holder.image);

The items seem to be stringified here, which is why my Uris are not loading.

How can we add support for this

ZGridActivity.java line 56

when pressing back from gallery it shows white blank screen i have tried Clear top but nothing works.. Please provide the solution asap..

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.widget.Toolbar.setVisibility(int)' on a null object reference

E/UncaughtException: java.lang.NoSuchMethodError: No virtual method load(Ljava/lang/String;)Lcom/bumptech/glide/DrawableTypeRequest; in class Lcom/bumptech/glide/RequestManager; or its super classes (declaration of 'com.bumptech.glide.RequestManager' appears in /data/app/~~vInwjvUpOScgFfsWB-7qEA==/example.com.dearst--mqEUkV1NKTXqxq3GwW00Q==/base.apk)
Please give the solution @mzelzoghbi @HendAlQett

I have used this code https://github.com/mzelzoghbi/ZGallery#grid-list-builder inside a onclick listener

the method setTitle("toolbar title) is not working for me. Also is it porrible to hide toolbar in the fullscreen gallery builder?

I have used this library for my project as it feeds all my requirements. Shall I mention this library anywhere apart from the code? Shall I face any legal issues if not so? If yes, how shall I mention it?

This is the part of GridImagesAdapter downloaded when I implemented Gallery, Which is different when I view it on github. Please Help

public void onBindViewHolder(ImageViewHolder holder, final int position) {
Glide.with(this.mActivity).load((String)this.imageURLs.get(position)).placeholder(this.imgPlaceHolderResId != -1 ? this.imgPlaceHolderResId : drawable.placeholder).into(holder.image);
holder.itemView.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
GridImagesAdapter.this.clickListener.onClick(position);
}
});
}

Adding optional counter in the toolbar of gallery to count the total images and shows the current one.

How to Clear cached images ?
Need call
Glide.get(this.activity).clearDiskCache();
and
Glide.get(this.activity).clearMemory();
in

public Object instantiateItem(ViewGroup container, int position) {
    View itemView = this.mLayoutInflater.inflate(layout.pager_item, container, false);
    final ImageView imageView = (ImageView)itemView.findViewById(id.iv);
    Glide.with(this.activity).load((String)this.images.get(position)).listener(new RequestListener() {
        public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
            return false;
        }

        public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
            ViewPagerAdapter.this.mPhotoViewAttacher = new PhotoViewAttacher(imageView);
            ViewPagerAdapter.this.mPhotoViewAttacher.setOnPhotoTapListener(new OnPhotoTapListener() {
                public void onPhotoTap(View view, float x, float y) {
                    if(ViewPagerAdapter.this.isShowing) {
                        ViewPagerAdapter.this.isShowing = false;
                        ViewPagerAdapter.this.toolbar.animate().translationY((float)(-ViewPagerAdapter.this.toolbar.getBottom())).setInterpolator(new AccelerateInterpolator()).start();
                        ViewPagerAdapter.this.imagesHorizontalList.animate().translationY((float)ViewPagerAdapter.this.imagesHorizontalList.getBottom()).setInterpolator(new AccelerateInterpolator()).start();
                    } else {
                        ViewPagerAdapter.this.isShowing = true;
                        ViewPagerAdapter.this.toolbar.animate().translationY(0.0F).setInterpolator(new DecelerateInterpolator()).start();
                        ViewPagerAdapter.this.imagesHorizontalList.animate().translationY(0.0F).setInterpolator(new DecelerateInterpolator()).start();
                    }

                }

                public void onOutsidePhotoTap() {
                }
            });
            return false;
        }
    }).into(imageView);
    container.addView(itemView);
    return itemView;
}

or add flag for don't use cache in Glide.with().load().diskCacheStrategy(DiskCacheStrategy.NONE).skipMemoryCache(true).into()

Hello,

I'm using the ZGallery library on android 4.4.2 and I haven't had any problems. But when I installed the app on android 9 the images were not loaded.

The same application works on Android 4.4.2 but not 9.

Is there any solution for this?

Thanks!

it would be nice if there is an option to show image title in gallery...

Hello, I have the following problem when I open the ZGrid the application opens correctly and displays the images but when I select it it shows the following message

Adding reversed RTL arrow for supporting RTL languages

Is it possible to load local images with zgallery? Passing in file paths does not seem to work (such as: file:///storage/emulated/0/foo.jpg), though I know glide supports loading local files.
