Is it possible to inflate a whole layout consisting of several views as a single coverflow item and set that layout in XML? It would be nice to see such an example.

This is the view I wish to have as a single coverflow item. Help appreciated!

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<ImageView
    android:id="@+id/positionViewIv"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:scaleType="fitCenter"
    android:src="@drawable/red_0"
    android:layout_centerInParent="true"/>
<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:layout_centerInParent="true">
    <TextView
        android:id="@+id/positionViewTv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="BALANCE"/>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="SUMMARY"/>
</LinearLayout>

I have added a Log.e line into the getChildStsticTransformation and noticed that this routine is called continuously, many times a second, never stopping. Not exactly a loop as the App remains responsive, but obviously this would be a significant drain on device resources. I have found that the problem is resolved by commenting out the following: if (android.os.Build.VERSION.SDK_INT >= 16) { // item.invalidate(); }

I am running on builds > 16 and yet I notice no visual difference after commenting as above. I do not use reflection. What exactly is the need for this additional invalidate?

Hello,

I started using this library and I'm having some trouble in understanding how can I make the coverflow to go to specific item (and animate). I was trying to force the click event on the item, but with no luck so far. Is there an easy way to do this? Thanks.

This library is awesome. But I have problem with default image position to display. I have an array image[] imgArr. By default, it always show imgArr[0]. Would you tell me how to change it to imgArr[1] or other?

Many thanks!!

Hi,

I'm using a negative spacing (coverFlow.setSpacing(-200)) to achieve a certain look. This works but creates item selection issues. For example if you touch the first item to the left it acts like if the second item was touched even if visually they don't overlap.

Is setSpacing the right way to reduce space between items ?

Thanks,

Julien

Hi, good library for this one but i have some issues, how can i get current position from this coverflow?. When i scroll to play with this, i need to get the center of child position. Please quick reply to this one.

Thanks in advance.

As the original FancyCoverFlow is short of an attribute about changing the position at Z-axis, which is compared to another similar effect like 3D-Gallery, this pull request is to fix that.

There is an annoying bug with images including drop shadows.

With this sample image for example : https://dl.dropboxusercontent.com/s/da9c10jdtk4g0c0/98014_presentations-01.png

I used a vertical LinearLayout to contain an ImageView and a TextView. Every time I scroll, the drop shadow of the image is like doubled, as if the Bitmap was drawn over the previous one at each call of the draw function.

I understand the problem but I can't find how to fix it.

I am trying to use a custom view group with cover flow. Instead of an XML layout or view , I am trying to load the view from fragment transaction. Here is the code I am trying to use here,

@Override

public View getCoverFlowItem(int i, View reuseableView, ViewGroup viewGroup) { CustomViewGroup fancyView = null; if (reuseableView != null) { fancyView = (CustomViewGroup) reuseableView; } else { fancyView = new CustomViewGroup(context); fancyView.getFrameLayout().setId(i+10000); fancyView.setLayoutParams(new FancyCoverFlow.LayoutParams(750, ViewGroup.LayoutParams.WRAP_CONTENT)); }

    FragmentManager fragmentManager = manager;
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.add(fancyView.getFrameLayout().getId(), ItemFragment.init(i));
    fragmentTransaction.commit();





    return fancyView;
}

class CustomViewGroup extends LinearLayout {

    // =============================================================================
    // Child views
    // =============================================================================

    private FrameLayout frameLayout;



    // =============================================================================
    // Constructor
    // =============================================================================

    private CustomViewGroup(Context context) {
        super(context);

        this.setOrientation(VERTICAL);

        this.frameLayout = new FrameLayout(context);

        LinearLayout.LayoutParams layoutParams = new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        this.frameLayout.setLayoutParams(layoutParams);





        this.addView(this.frameLayout);
    }

    // =============================================================================
    // Getters
    // =============================================================================

    private FrameLayout getFrameLayout() {
        return frameLayout;
    }
}    

For me the issue is the getView function is getting called infinite number of times for value i=0. But If I don't commit a fragment transaction it works normal(ie getting called only once for index 0)

Any clue on whats happening here?

Thanks

It's a very nice libray..

but when I use it and try to make the item not noly just ImageView...and then play it over and over..OOM Will Occurs...

for help...

On the example of Reflection ViewGroupReflectionExample.java,if you try to scroll over the cover by touching over the buttons it does'nt work as expected.

Please see screenshots.

Problem: The items in the coverflow were incorrectly stacking (to the right of the selected item) and was an eyesore when overlapping.

Solution: Override the gallery getChildDrawingOrder The solution has been tested, see the 'improvement' screenshot (NB the images to the right of the selected item are now correctly stacked)

fixed: WRAP_CONTENT will now work for child groups -> onMeasure inheritance over LinearLayout instead of ViewGroup->View

fixed: due to creation of new Gallery.LayoutParams from the wrappedView params we are save in supporting the superset from ViewGroup.LayoutParams
