Android 实现局部图片滑动指引效果

而ViewPager的事件监听器代码如下：

　　// 滑动页面更改事件监听器
  private class ImagePageChangeListener implements OnPageChangeListener {
    @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 index) { 
      pageIndex = index;
      slideLayout.setPageIndex(index);
      tvSlideTitle.setText(parser.getSlideTitles()[index]);
      
      for (int i = 0; i < imageCircleViews.length; i++) { 
        imageCircleViews[index].setBackgroundResource(R.drawable.dot_selected);
        
        if (index != i) { 
          imageCircleViews[i].setBackgroundResource(R.drawable.dot_none); 
        } 
      }
    } 
  }
