ImageCoverFlow is an open source Android library that allows developers to easily create applications with a cover flow effect to show images. This library does not extend Gallery. Feel free to use it all you want in your Android apps provided that you cite this project and include the license in your app.

1. Via XML:

<com.dolphinwang.imagecoverflow.CoverFlowView
    xmlns:imageCoverFlow="http://schemas.android.com/apk/res-auto"
    android:id="@+id/coverflow"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="20dp"
    android:paddingRight="20dp"
    imageCoverFlow:coverflowGravity="center_vertical"
    imageCoverFlow:coverflowLayoutMode="wrap_content"
    imageCoverFlow:reflectionGap="10dp"
    imageCoverFlow:reflectionHeight="30%"
    imageCoverFlow:visibleImage="5" />

2. Programatically (via Java):

CoverFlowView<MyCoverFlowAdapter> mCoverFlowView =
    (CoverFlowView<MyCoverFlowAdapter>) findViewById(R.id.coverflow);

mCoverFlowView.setCoverFlowGravity(CoverFlowGravity.CENTER_VERTICAL);
mCoverFlowView.setCoverFlowLayoutMode(CoverFlowLayoutMode.WRAP_CONTENT);
mCoverFlowView.setReflectionHeight(30);
mCoverFlowView.setReflectionGap(20);
mCoverFlowView.setVisibleImage(5);

MyCoverFlowAdapter adapter = new MyCoverFlowAdapter(this);
mCoverFlowView.setAdapter(adapter);

TIPS:

• Method setAdapter() should be called after all properties of CoverFlow are settled.
• If you want to load image dynamically, you can call method notifyDataSetChanged() when bitmaps are loaded.

mCoverFlowView.setStateListener(new CoverFlowView.StateListener() {
    @Override
    public void imageOnTop(CoverFlowView<MyCoverFlowAdapter> view, int position,
            float left, float top, float right,float bottom) {
        // TODO
    }

    @Override
    public void invalidationCompleted(CoverFlowView view) {
        // TODO
    }
});

if you want to listen for click events of showing images, you can set a ImageClickListener to it:

mCoverFlowView.setImageClickListener(new CoverFlowView.ImageClickListener() {
            @Override
            public void onClick(CoverFlowView coverFlowView, int position) {
				// TODO
            }
});

If you want to listen for long click events of the top image, you can set a ImageLongClickListener to it:

mCoverFlowView
    .setImageLongClickListener(new CoverFlowView.ImageLongClickListener() {
        @Override
        public void onLongClick(CoverFlowView view, int position) {
            // TODO
        }
    });

Users can use method setSelection(int position) to show a specific position at the top.

1. You can override method getCustomTransformMatrix() to make more transformations for images (there is some annotated code which shows how to make image y-axis rotation).
2. You should never override method onLayout() to layout any of CoverFlowView’s children, because all of image will draw on the canvas directly.
