详细说明：
一个ViewPager的库，支持水平翻页，上下翻页，无限翻页。项目地址：https://github.com/alexzaitsev/freepager 效果图： 如何使用：创建仅支持垂直的 xml布局中： java ：public class MainActivity extends Activity implements ViewFactory{ Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); this.setContentView(R.layout.main); InfiniteVerticalPager verticalPager = (InfiniteVerticalPager) this.findViewById(R.id.viewPager); verticalPager.setFactory(this); verticalPager.instantiate(); } Override public View makeView(int vertical, int horizontal) { Button btn = new Button(this); btn.setText("vertical " vertical); btn.setBackgroundColor(0xFFe6e6e6); System.out.println("MainActivity:makeView"); return btn; } }2. 创建仅支持水平的 xml布局代码： java：public class MainActivity extends Activity implements ViewFactory{ Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); this.setContentView(R.layout.main); ViewPager viewPager = (ViewPager)this.findViewById(R.id.viewPager); viewPager.setAdapter(new InfiniteHorizontalPagerAdapter(this, 0)); viewPager.setCurrentItem(Constants.START_INDEX); } Override public View makeView(int vertical, int horizontal) { Button btn = new Button(this); btn.setText("horizontal " horizontal); btn.setBackgroundColor(0xFFe6e6e6); System.out.println("MainActivity:makeView"); return btn; } }3. 创建既水平又垂直的 xml布局： java：public class MainActivity extends Activity implements OnPageChangeListener{ private int mCurrentHorizontalIndex = 0; Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); this.setContentView(R.layout.main); InfiniteVerticalPager verticalPager = (InfiniteVerticalPager)this.findViewById(R.id.viewPager); verticalPager.setFactory(mVerticalViewFactory); verticalPager.instantiate(); } private ViewFactory mVerticalViewFactory = new ViewFactory() { static final int VIEWS_TO_INITIALIZE_COUNT = 3; private int mViewsToInitilizeLeft = VIEWS_TO_INITIALIZE_COUNT; Override public View makeView(int vertical, int horizontal) { int normalizedHorizontal = 0; if (mViewsToInitilizeLeft > 0) { mViewsToInitilizeLeft--; } else { normalizedHorizontal = mCurrentHorizontalIndex; } InfiniteHorizontalPager pager = new InfiniteHorizontalPager(MainActivity.this, vertical, normalizedHorizontal, mHorizontalViewFactory); pager.getPager().setOnPageChangeListener(MainActivity.this); return pager.getPager(); } }; private ViewFactory mHorizontalViewFactory = new ViewFactory() { Override public View makeView(int vertical, int horizontal) { Button btn = new Button(MainActivity.this); btn.setText("Horizontal " horizontal "\nVertical " vertical); btn.setBackgroundColor(0xFFe6e6e6); return btn; } }; Override public void onPageScrollStateChanged(int arg0) { // TODO Auto-generated method stub } Override public void onPageScrolled(int arg0, float arg1, int arg2) { // TODO Auto-generated method stub } Override public void onPageSelected(int arg0) { // TODO Auto-generated method stub } }
