ViewPager引导页Demo_自动循环ViewPager源码下载

分享一个简单的ViewPager例子、代码很简单、只有一个MainActivity、很适合刚刚使用ViewPager的哥们看、里面有内嵌一下MyAdapter、继承至PagerAdapter、另外要说明的是这个ViewPager是可以无线循环的

onCreate部分代码

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.main_activity);

    imageView1 = (ImageView) findViewById(R.id.ad1);
    imageView2 = (ImageView) findViewById(R.id.ad2);
    imageView3 = (ImageView) findViewById(R.id.ad3);
    list = new ArrayList<ImageView>();
    imagesid = new int[] { R.drawable.qq, R.drawable.ee, R.drawable.rr };
    // imageViews = new ImageView[imagesid.length];

    LinearLayout linearLayout = (LinearLayout) findViewById(R.id.viewGroup);

    viewPager = (ViewPager) findViewById(R.id.viewPager);


    for (int i = 0; i < imagesid.length; i  ) {
        ImageView imageView = new ImageView(this);
        imageView.setImageResource(imagesid[i]);
        // imageView.setScaleType(ScaleType.CENTER_CROP);
        list.add(imageView);
    }

    viewPager.setAdapter(new MyAdapter());
    viewPager.setOnPageChangeListener(new MyListener());
    viewPager.setCurrentItem(300);
    mHandler.postDelayed(mRunnable, 2000);
}

Adapter代码

public Object instantiateItem(View arg0, int arg1) {
    // TODO Auto-generated method stub
    try {
        //((ViewPager) arg0).addView(list.get(arg1),0);
        ((ViewPager) arg0).addView((View) list.get(arg1 % list.size()), 0);
    } catch (Exception e) {
        // TODO: handle exception
    }

    return list.get(arg1 % list.size());

}

最后给贴上Demo的源代码、希望对大家有用、有兴趣的哥们可以下载看看
