这个Demo是可以左右滑动的，并且可以在布局文件中添加组件点击事件。主要是利用ViewPager类来实现的。

Activity程序：

package com.example.test;import java.util.ArrayList;import java.util.List;import android.os.Bundle;import android.app.Activity;import android.app.AlertDialog;import android.content.Context;import android.content.DialogInterface;import android.view.LayoutInflater;import android.view.Menu;import android.view.View;import android.widget.ImageView;import android.widget.LinearLayout;import android.support.v4.view.PagerAdapter;import android.support.v4.view.ViewPager;public class TActivity extends Activity {private ViewPager mViewPager;private LinearLayout lin1, lin2;private Context cxt;private ViewPagerAdapter mAdapter;private List<View> mListViews;private LayoutInflater mInflater;boolean result = true;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        cxt = this;                mListViews = new ArrayList<View>();        mInflater = getLayoutInflater();        mListViews.add(mInflater.inflate(R.layout.tab1, null));        mListViews.add(mInflater.inflate(R.layout.tab2, null));                mAdapter = new ViewPagerAdapter(mListViews);        mViewPager = (ViewPager)findViewById(R.id.mViewPager);        mViewPager.setAdapter(mAdapter);            }    /*     * ViewPager适配器类     * 主要用到两个函数：instantiateItem和destroyedItem     * instantiateItem主要实现新的画面的添加     * destroyedItem主要实现老的画面去处     */    private class ViewPagerAdapter extends PagerAdapter{    private List<View> list;        public ViewPagerAdapter(List<View> list) {// TODO Auto-generated constructor stub    this.list = list;}    @Overridepublic int getCount() {// TODO Auto-generated method stubreturn list.size();}@Overridepublic Object instantiateItem(View container, int position) {// TODO Auto-generated method stub((ViewPager)container).addView(list.get(position),0);if (position == 0) {ImageView download_btn = (ImageView)container.findViewById(R.id.download_btn);download_btn.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubnew AlertDialog.Builder(TActivity.this)                          .setTitle("说明")                          .setMessage("单个页卡内按钮事件测试")                          .setNegativeButton("确定",                                 new DialogInterface.OnClickListener() {                                      public void onClick(                                              DialogInterface dialog,                                              int which) {                                     }                              }).show();}});}return list.get(position);}@Overridepublic void destroyItem(View container, int position, Object object) {// TODO Auto-generated method stub((ViewPager)container).removeView(list.get(position));}@Overridepublic boolean isViewFromObject(View arg0, Object arg1) {// TODO Auto-generated method stubreturn arg0 == arg1;}        }        @Override    public boolean onCreateOptionsMenu(Menu menu) {        getMenuInflater().inflate(R.menu.main, menu);        return true;    }    }
