简单的viewPager

总结，无非就是一个viewpager控件，然后构建一个pageradater适配器，通过addview方法，把View放进list数组里面，然后把list里面的view，根据position逐个添加进去

            }

            @Override
            public int getCount() {
                return mList.size();
            }

            @Override
            public void destroyItem(ViewGroup container, int position,
                                    Object object) {
                container.removeView(mList.get(position));
            }

            @Override

                container.addView(mList.get(position));

            }
        };
        mViewPager.setAdapter(mPagerAdapter);
    }
}
