教程：ViewPager

第一步：在布局文件里添加ViewPager控件

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

第二步：自定义ViewPager适配器

import java.util.List;
import android.support.v4.view.PagerAdapter;
import android.view.View;
import android.view.ViewGroup;

public class ViewAdapter extends PagerAdapter{
	
	private List<View> listData; 
    
    public ViewAdapter(List<View> mListViews) { 
        listData = mListViews;//构造方法，参数是我们的页卡，这样比较方便。 
    } 

    @Override 
    public void destroyItem(ViewGroup container, int position, Object object)   {    
        container.removeView(listData.get(position));//删除页卡 
    } 


    @Override 
    public Object instantiateItem(ViewGroup container, int position) {  //这个方法用来实例化页卡        
         container.addView(listData.get(position), 0);//添加页卡 
         return listData.get(position); 
    } 

	@Override
	public int getCount() {
		// TODO Auto-generated method stub
		return listData.size();
	}

	@Override
	public boolean isViewFromObject(View arg0, Object arg1) {
		// TODO Auto-generated method stub
		return arg0==arg1;//官方提示这样写 
	}

}

第三步：初始化ViewPager控件，设置适配器

import java.util.ArrayList;
import android.os.Bundle;
import android.app.Activity;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;

public class MainActivity extends Activity {
	
	ViewAdapter mAdapter;
	
	private ViewPager vpTest;//滑动view

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        initView();//初始化控件
        vpSetData();//添加数据、设置适配器
    }
    
    private void initView() {
		// TODO Auto-generated method stub
		vpTest = (ViewPager) findViewById(R.id.vpTest);
	}

	private void vpSetData() {
		// TODO Auto-generated method stub
        ArrayList<View> viewList = new ArrayList<View>();// 将要分页显示的View装入数组中 
        viewList.add(initPagerItem()); 
        viewList.add(initPagerItem());
        
        mAdapter = new ViewAdapter(viewList);
        vpTest.setAdapter(mAdapter);
	}
	
	//返回ViewPager每个view
	private View initPagerItem() {
		LayoutInflater mLayoutInflater = getLayoutInflater().from(this);
		View layout1 = mLayoutInflater.inflate(R.layout.view_item, null);
		return layout1;
	}
}
