getSerializableExtra Error

Hi. I'm trying to set my contents from java class but it gives me the following error: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.samanefarhangi/com.example.samanefarhangi.PullToZoomScrollActivity}: java.lang.ClassCastException: com.example.samanefarhangi.pulllib.PullToZoomScrollViewEx cannot be cast to com.example.samanefarhangi.pulllib.PullToZoomScrollView at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2439) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2495) at android.app.ActivityThread.access$800(ActivityThread.java:153) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1349) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:157) at android.app.ActivityThread.main(ActivityThread.java:5633) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:896) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:712) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.ClassCastException: com.example.samanefarhangi.pulllib.PullToZoomScrollViewEx cannot be cast to com.example.samanefarhangi.pulllib.PullToZoomScrollView

here is the code: private void loadViewForCode() {

    feed = (FeedItem) this.getIntent().getSerializableExtra("feed");
    PullToZoomScrollView scrollView = (PullToZoomScrollView) findViewById(R.id.scroll_view);
    View headView = LayoutInflater.from(this).inflate(R.layout.profile_head_view, null, false);


    TextView title = (TextView) headView.findViewById(R.id.tv_title);
    title.setText(feed.getTitle());

    TextView author = (TextView) headView.findViewById(R.id.tv_author);
    author.setText(feed.getAuthor());

    TextView date = (TextView) headView.findViewById(R.id.tv_date);
    date.setText(feed.getDate());

    View zoomView = LayoutInflater.from(this).inflate(R.layout.profile_zoom_view, null, false);

    ImageView contentImage = (ImageView) headView.findViewById(R.id.iv_user_head);
    try {
        new ImageDownloaderTask(contentImage).execute(feed.getAttachmentUrl());
    }catch (Exception e){
        e.printStackTrace();
    }

    View contentView = LayoutInflater.from(this).inflate(R.layout.profile_content_view, null, false);

    TextView htmlTextView = (TextView) contentView.findViewById(R.id.tv_content);
    htmlTextView.setText(Html.fromHtml(feed.getContent(), null, null));

    scrollView.setHeaderContainer(headView);
    scrollView.setZoomView(zoomView);
    scrollView.setContentContainerView(contentView);
}

I think it's a library problem!

zoomView无法正常呈现，被contentView遮挡

很感谢提供这么酷的控件，但在使用中遇到一些问题英文比较烂，描述就直接写中文了我在Activity中仅有此控件：PullToZoomScrollViewEx 但是呈现结果却不尽人意，zoomView被遮挡，且图片高度较高的情况下无法正常缩放

代码如下如下 MainActivity

activity_main.xml

contentView

zoomView

headerView

顺便说一句，Gradle添加有问题，Manifest提示错误

contenview里有viewpager时，mRootView的测量高度大于mRootContainer的测量高度

测量高度我指getMeasuredHeight。已经在源代码里将mRootContainer的layoutparms宽高设置为了match_parent 导致的结果就是contentView里match_parent的组件并没有占据剩下的整个屏幕（我碰到的组件是viewpager没有显示）。

Zoom header on fling?

Is it possible to start the zooming effect while flinging/fast scrolling? I mean, right now if you try to fling and you reach the top, there is no zooming. It would be really cool to add this feature to improve motion. Let me know if you need any clarification, I don't know if I explained it clear enough

可以说一下实现的思路么，我看源码那个缩放比例看了好久，没有注释

      if ((!mIsFinished) && (mScale > 1.0D)) {
                float currentThreadTime=SystemClock.currentThreadTimeMillis();
                               float f1 = ((float) SystemClock.currentThreadTimeMillis()-

(float) mStartTime) / (float) mDuration; f2 = mScale - (mScale - 1.0F) * PullToZoomScrollViewEx.sInterpolator.getInterpolation(f1);
