您可以使用视图寻呼机。

<android.support.v4.view.ViewPager 
     android:id="@+id/viewpager" 
     android:layout_width="match_parent" 
     android:layout_height="300dp" /> 

     int[] images={R.drawable.pr1,R.drawable.pr2,R.drawable.pr3,R.drawable.pr4,R.drawable.pr5}; 
viewPager=(ViewPager)findViewById(R.id.viewpager); 
    adapter=new CircleViewAdapter(StartScreen.this,images); 
    viewPager.setAdapter(adapter); 

适配器：

public class CircleViewAdapter extends PagerAdapter { 
private Context mContext; 
LayoutInflater mLayoutInflater; 
private int[] mResources; 

public CircleViewAdapter(Context context, int[] resources) { 
    mContext = context; 
    mLayoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    mResources = resources; 
} 

@Override 
public Object instantiateItem(ViewGroup container, int position) { 

    View itemView = mLayoutInflater.inflate(R.layout.flipper_item,container,false); 
    ImageView imageView = (ImageView) itemView.findViewById(R.id.flipimage); 
    imageView.setImageResource(mResources[position]); 

    container.addView(itemView); 
    return itemView; 
} 

@Override 
public void destroyItem(ViewGroup collection, int position, Object view) { 
    collection.removeView((View) view); 
} 

@Override 
public int getCount() { 
    return mResources.length; 
} 

@Override 
public boolean isViewFromObject(View view, Object object) { 
    return view == object; 
} 

}
