FINAL EFFECT

REBOUND EFFECT

#ImageView transition with ViewPager click view to see detail in other layout...

Feature: Working on...

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

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.touchEnable(false);//disable touch

2.Handle PhotoView Click

    //view is PhotoView normally,when load inmage from remote,you need call view.setEnable(false) 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, ViewPagerFragment.getInstance(bundle), "ViewPagerFragment")
                                .addToBackStack(null).commit();
    }

3.If u use universalimageloader to get remote image,now is more convenient

dependencies {
    compile 'com.brucetoo:library:1.0.0'{
      exclude module: 'support-v4'
    }
}
 
 Then use ViewPagerFragment like ’Handle PhotoView Click‘
 

#ActivityAnimation Usage

  Pre activity onCreate()..
  ActivityTransitionEnterHelper.with(this).fromView(fromView).imageUrl(imgUrl).start(Test.class);
  Sub activity onCreate()..
  transitionExitHelper = ActivityTransitionExitHelper.with(getIntent()).toView(mImageView).background(mBackgroudnView).start(savedInstanceState);
                      @Override
                      public void onBackPressed() {
                          transitionExitHelper.runExitAnimation(new Runnable() {
                              @Override
                              public void run() {
                                  finish();
                              }
                          });
                      }
                      @Override
                      public void finish() {
                          super.finish();
                          // override transitions to skip the standard window animations
                          overridePendingTransition(0, 0);
                      }
