Xbanner圆角展现轮播图

在Xbanner的基础上新添加圆角展现
xbanner地址： xiaohaibin/XBanner

展现效果如下：

展现的样式两边留白圆角展现
滑动的样式展现

假如符合你想要设置的效果那继续看后续的具体代码添加：

  //圆角方法        @TargetApi(Build.VERSION_CODES.LOLLIPOP)        public void setClipViewCornerRadius(View view, final int radius) {            if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {                //不支持5.0版本以下的系统                //5.0以下，值设置边距                view.setPadding(40, 0, 40, 0);                return;            }            if (view == null) return;            if (radius <= 0) {                return;            }            view.setOutlineProvider(new ViewOutlineProvider() {                @Override                public void getOutline(View view, Outline outline) {//                    outline.setRoundRect(20, 20, view.getWidth()-40,   view.getHeight()-40, radius);                    outline.setRoundRect(40, 0, view.getWidth() - 40, view.getHeight(), radius);//                    Rect rect = new Rect();//                    view.getGlobalVisibleRect(rect);//                    int leftMargin = 40;//                    int topMargin = 40;//                    Rect selfRect = new Rect(leftMargin, topMargin,//                            rect.right - rect.left - leftMargin, rect.bottom - rect.top - topMargin);//                    outline.setRoundRect(selfRect, 30);                }            });            view.setClipToOutline(true);        }

在instantiateItem返回view之前设置圆角

 @NonNull        @Override        public Object instantiateItem(@NonNull ViewGroup container, final int position) {            if (getRealCount() == 0) {                return null;            }            final int realPosition = position % getRealCount();            View view;            if (mLessViews == null) {                view = mViews.get(realPosition);            } else {                view = mLessViews.get(position % mLessViews.size());            }            if (container.equals(view.getParent())) {                container.removeView(view);            }            if (mOnItemClickListener != null && mDatas.size() != 0) {                view.setOnClickListener(new OnDoubleClickListener() {                    @Override                    public void onNoDoubleClick(View v) {                        mOnItemClickListener.onItemClick(XbannerRoundImg.this, mDatas.get(realPosition), v, realPosition);                    }                });            }            if (null != mAdapter && mDatas.size() != 0) {                mAdapter.loadBanner(XbannerRoundImg.this, mDatas.get(realPosition), view, realPosition);            }            ViewParent parent = view.getParent();            if (parent != null) {                ((ViewGroup) parent).removeView(view);            }            //在返回view的时候设置圆角            setClipViewCornerRadius(view, 30);            container.addView(view);            return view;        }
