Greeting Card Flip-View Animation

I'm working on greeting card application and i need card flip-view type of View. i've added images for same. I've been through multiple flip-view like libraries and i found android-flipview more suitable for my requirement. I've made changes in this library to make it flip from left corner like greeting card. i'm adding code and screenshot for same.

But, it doesn't work like what i need.

View_Dual_card.java File,I made Changes Like this:

public synchronized void buildTexture(FlipRenderer renderer, GL10 gl) {
        if (screenshot != null) {
            if (texture != null)
                texture.destroy(gl);
            texture = Texture.createTexture(screenshot, renderer, gl);
            recycleScreenshot();

            topCard.setTexture(texture);
            bottomCard.setTexture(texture);

            final float viewHeight = texture.getContentHeight();
            final float viewWidth = texture.getContentWidth();
            final float textureHeight = texture.getHeight();
            final float textureWidth = texture.getWidth();

            if (orientationVertical) {
                topCard.setCardVertices(new float[] { 0f, viewHeight, 0f, // top left
                        0f, viewHeight / 2.0f, 0f, // bottom left
                        viewWidth, viewHeight / 2f, 0f, // bottom right
                        viewWidth, viewHeight, 0f // top right
                });

                topCard.setTextureCoordinates(new float[] { 0f, 0f, 0f,
                        viewHeight / 2f / textureHeight,
                        viewWidth / textureWidth,
                        viewHeight / 2f / textureHeight,
                        viewWidth / textureWidth, 0f });

                bottomCard.setCardVertices(new float[] { 0f, viewHeight / 2f,
                        0f, // top left
                        0f, 0f, 0f, // bottom left
                        viewWidth, 0f, 0f, // bottom right
                        viewWidth, viewHeight / 2f, 0f // top right
                        });

                bottomCard.setTextureCoordinates(new float[] { 0f,
                        viewHeight / 2f / textureHeight, 0f,
                        viewHeight / textureHeight, viewWidth / textureWidth,
                        viewHeight / textureHeight, viewWidth / textureWidth,
                        viewHeight / 2f / textureHeight });
            } else {
                topCard.setCardVertices(new float[] { 0f, viewHeight, 0f, // top left
                        0f, 0f, 0f, // bottom left
                        viewWidth /27f, 0f, 0f, // bottom right
                        viewWidth /27f, viewHeight, 0f // top right
                });

                topCard.setTextureCoordinates(new float[] { 0f, 0f, 0f,
                        viewHeight / textureHeight,
                        viewWidth / 27f / textureWidth,
                        viewHeight / textureHeight,
                        viewWidth / 27f / textureWidth, 0f });

                bottomCard.setCardVertices(new float[] {0f,
                        viewHeight, 0f, // top left
                        0f, 0f, 0f, // bottom left
                        viewWidth, 0f, 0f, // bottom right
                        viewWidth, viewHeight, 0f // top right
                        });

                bottomCard.setTextureCoordinates(new float[] {
                        viewWidth /27f / textureWidth, 0f,
                        viewWidth /27f / textureWidth,
                        viewHeight / textureHeight, viewWidth / textureWidth,
                        viewHeight / textureHeight, viewWidth / textureWidth,
                        0f });
            }

            checkError(gl);
        }
    }

What i want:
