Android使用ViewPager实现图片左右循环滑动自动播放

package com.example.viewpagerdemo; 
import android.app.Activity; 
import android.os.Bundle; 
import android.support.v4.view.PagerAdapter; 
import android.support.v4.view.ViewPager; 
import android.support.v4.view.ViewPager.OnPageChangeListener; 
import android.view.View; 
import android.view.ViewGroup; 
import android.view.ViewGroup.LayoutParams; 
import android.widget.ImageView; 
import android.widget.LinearLayout; 
public class TwoActivity extends Activity implements OnPageChangeListener{ 
/** 
* ViewPager 
*/ 
private ViewPager viewPager; 
/** 
* 装点点的ImageView数组 
*/ 
private ImageView[] tips; 
/** 
* 装ImageView数组 
*/ 
private ImageView[] mImageViews; 
/** 
* 图片资源id 
*/ 
private int[] imgIdArray ; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.activity_main); 
ViewGroup group = (ViewGroup)findViewById(R.id.viewGroup); 
viewPager = (ViewPager) findViewById(R.id.viewPager); 
//载入图片资源ID 
imgIdArray = new int[]{R.drawable.item01, R.drawable.item02, R.drawable.item03, R.drawable.item04, 
R.drawable.item05,R.drawable.item06, R.drawable.item07, R.drawable.item08}; 
//将点点加入到ViewGroup中 
tips = new ImageView[imgIdArray.length]; 
for(int i=0; i

@Override 
public void destroyItem(View container, int position, Object object) { 
// ((ViewPager)container).removeView(mImageViews[position % mImageViews.length]); 
} 
instantiateItem(View container, int position)增加异常扑捉
[java] view plain copy 
@Override 
public Object instantiateItem(View container, int position) { 
try { 
((ViewPager)container).addView(mImageViews[position % mImageViews.length], 0); 
}catch(Exception e){ 
//handler something 
} 
return mImageViews[position % mImageViews.length]; 
}
