Viewpage实现左右无限滑动

public class MainActivity extends Activity implements
		OnPageChangeListener {
	private ViewPager viewpager;
	private int view[] = { R.layout.a, R.layout.b, R.layout.c };
	private List<View> data = new ArrayList<View>();

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		init();
		initViewPagerData();
	}

	private void initViewPagerData() {
		data.add(0,
				LayoutInflater.from(this).inflate(view[view.length - 1], null));
		for (int i = 0; i < view.length; i++) {
			data.add(i + 1, LayoutInflater.from(this).inflate(view[i], null));
		}
		data.add(view.length + 1,
				LayoutInflater.from(this).inflate(view[0], null));

		viewpager.setAdapter(new ViewPagerAdapter(data, this));
		viewpager.setCurrentItem(1, false);
	}

	private void init() {
		// 初始化界面
		viewpager = (ViewPager) findViewById(R.id.viewpager);
		// 添加事件
		viewpager.setOnPageChangeListener(this);

	}

	@Override
	public void onPageScrollStateChanged(int arg0) {

	}

	@Override
	public void onPageScrolled(int arg0, float arg1, int arg2) {
		// 无限循环滑动
		if (view.length > 1) {// 多于一个view才会循环跳转
			if (arg0 == 0 && arg2 == 0) {
				// 切换循环更加流畅，不会出现生硬的切换感觉
				arg0 = view.length;
				viewpager.setCurrentItem(arg0, false);
			} else if (arg0 > view.length) {
				viewpager.setCurrentItem(1, false);
			}
		}
	}

	@Override
	public void onPageSelected(int arg0) {

	}
}
