Usage

From source file:com.dm.xz.views.PinnedSectionListView.java

@Override
protected void dispatchDraw(Canvas canvas) {
    super.dispatchDraw(canvas);

    if (mPinnedSection != null) {

        // prepare variables
        int pLeft = getListPaddingLeft();
        int pTop = getListPaddingTop();
        View view = mPinnedSection.view;

        // draw child
        canvas.save();// www . j a va 2  s.com

        int clipHeight = view.getHeight()
                + (mShadowDrawable == null ? 0 : Math.min(mShadowHeight, mSectionsDistanceY));
        canvas.clipRect(pLeft, pTop, pLeft + view.getWidth(), pTop + clipHeight);

        canvas.translate(pLeft, pTop + mTranslateY);
        drawChild(canvas, mPinnedSection.view, getDrawingTime());

        if (mShadowDrawable != null && mSectionsDistanceY > 0) {
