ImageBrowse fragment can use to browse image with transition animation

The same as the latest android WeChat moments image browse effect

FINAL EFFECT

Feature: Big improvement

Add thumbnail support when full image is not cache just like WeChat does.

New add padding and margin support in ImageBrowseFragment

1.original view: just like normal imageView but with zoom effect
2.detail view:
① single click back to pre layout with shrink effect
② double click to zoom effect(*2.5)
③ more gesture see details code
3.if u have more than one imageview can display with ViewPager
random click original imageview,and scroll ViewPager to any position,
than u press back key,or single click detail,u will see original view's
position is the same as ViewPager‘s current position.

4.load image from remote u can't click item until it finished

5.ViewPager has rebound effect when edge of ViewPager is available..

#USAGE for fragment

1.Handle init PhotoView(also available xml)

    PhotoView p = new PhotoView(MainActivity.this);
    p.setLayoutParams(new AbsListView.LayoutParams((int) (getResources().getDisplayMetrics().density * 100), (int) (getResources().getDisplayMetrics().density * 100)));
    p.setScaleType(ImageView.ScaleType.CENTER_CROP);
    p.setEnabled(false);//u can't click view until image load completed
    ...//load image and put it into PhotoView
    p.disenable(false);//disable touch

2.Handle PhotoView Click

    //view is PhotoView normally,when load image from remote,you need call view.enable() to
    //let PhotoView can't be clicked util it load completed
    if(view.isEnabled()) { 
    Bundle bundle = new Bundle();
    bundle.putStringArrayList("imgs", imgList);//all PhotoView url(remote)
    bundle.putParcelable("info", ((PhotoView) view).getInfo());//click PhotoView ImageInfo
    bundle.putInt("position", position);//click position
    imgImageInfos.clear();
    //NOTE:if imgList.size >= the visible count in single screen,i will cause NullPointException
    //because item out of screen have been replaced/reused
    for (int i = 0; i < imgList.size(); i++) {
        imgImageInfos.add(((PhotoView) parent.getChildAt(i)).getInfo());//remember all PhotoView ImageInfo
    }
    bundle.putParcelableArrayList("infos", imgImageInfos);
    //attach fragment to Window
    getSupportFragmentManager().beginTransaction().replace(Window.ID_ANDROID_CONTENT, ImageBrowseFragment.getInstance(bundle), "ViewPagerFragment")
                                .addToBackStack(null).commit();
    }

More detail please see demo code.

#USEAGE for Dialog fragment

handle where you click

    root.post(new Runnable() { // in case root view not inflate complete
                         @Override
                         public void run() {
                             Bundle bundle = new Bundle();
                             bundle.putStringArrayList(ImageInfo.INTENT_IMAGE_URLS, imgList);
                             final ImageInfo preImgInfo = ((PhotoView) view).getInfo();
                             bundle.putParcelable(ImageInfo.INTENT_CLICK_IMAGE_INFO, preImgInfo);
                             bundle.putInt(ImageInfo.INTENT_CLICK_IMAGE_POSITION, position);
                             imgImageInfos.clear();
                             for (int i = 0; i < imgList.size(); i++) {
                                 imgImageInfos.add(((PhotoView) parent.getChildAt(i)).getInfo());
                             }
                             bundle.putParcelableArrayList(ImageInfo.INTENT_IMAGE_INFOS, imgImageInfos);
                             int[] position = new int[2];
                             root.getLocationOnScreen(position);
                             //Must correct the ImageInfo in DialogFragment
                             preImgInfo.correct(position, getStatusBarHeight());
                             for (ImageInfo item : imgImageInfos) {
                                 item.correct(position,getStatusBarHeight());
                             }
                             ImageBrowseDialogFragment.newInstance(bundle).show(getSupportFragmentManager(), ImageBrowseDialogFragment.class.getSimpleName());
                         }
                     });

See ImageBrowseDialogFragment If the anchor activity is fullscreen,we need care about if ImageBrowseDialogFragment is fullscreen

    @Override
      public void onActivityCreated(Bundle savedInstanceState) {
          super.onActivityCreated(savedInstanceState);
          /**NOTE if the anchor activity is FullScreen,the following code must be used.
          and {@link ImageInfo#correct(int[], int)} the second params must be Zero..
          */
  //      getDialog().getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
          getDialog().getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
      }

#NOTE if you use ReboundViewPager to get rebound effect,this way may cause a problem when doing scale operation at first or last PhotoView try use ViewPager instead
