我们在一个apk中第一次開始的时候，会有一个guide界面。一般使用ViewPager来完毕。

布局文件例如以下：

<?

xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent" >

    <android.support.v4.view.ViewPager

        android:id="@+id/guide_viewpager"

        android:layout_width="match_parent"

        android:layout_height="match_parent" >

    </android.support.v4.view.ViewPager>

    <Button

        android:id="@+id/guide_button"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentBottom="true"

        android:layout_centerHorizontal="true"

        android:layout_marginBottom="20dp"

        android:paddingLeft="30dp"

        android:paddingRight="30dp"

        android:text="開始体验"

        android:textSize="20sp"

        android:visibility="gone" />

</RelativeLayout>

这就是一个想到Activity GuideActivity.java

package com.xlg.news;

import java.util.ArrayList;

import java.util.List;

import com.xlg.news.adapters.WelcomeViewPagerAdapter;

import com.xuliugen.newsclient.R;

import android.app.Activity;

import android.content.Intent;

import android.opengl.Visibility;

import android.os.Bundle;

import android.support.v4.view.ViewPager;

import android.support.v4.view.ViewPager.OnPageChangeListener;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.ImageView;

public class GuideActivity extends Activity {

    private ViewPager guideViewPager;

    private Button guideButton;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.guide_activity);

        guideViewPager = (ViewPager) this.findViewById(R.id.guide_viewpager);

        guideButton = (Button) this.findViewById(R.id.guide_button);

        //获取图片ImageView资源

        final List<ImageView> imageViewsList = initData();

        WelcomeViewPagerAdapter viewPagerAdapter = new WelcomeViewPagerAdapter(GuideActivity.this,imageViewsList);

        guideViewPager.setAdapter(viewPagerAdapter);

        /**

         * 设置guide ViewPager滑动的时候的监听事件

         */

        guideViewPager.setOnPageChangeListener(new OnPageChangeListener() {

            /**

             * 已经选中某一页的时候

             */

            @Override

            public void onPageSelected(int position) {

                //已经到了最后一页

                if(position == imageViewsList.size()-1){

                    guideButton.setVisibility(View.VISIBLE);

                    guideButton.setOnClickListener(new OnClickListener() {

                        @Override

                        public void onClick(View v) {

                            //进入最后一页设置向导页，点击按钮完毕功能

                        }

                    });

                }else{

                    guideButton.setVisibility(View.GONE);

                }

            }

            /**

             *

             * 在页面的滑动过程中

             */

            @Override

            public void onPageScrolled(int position, float arg1, int arg2) {

            }

            /**

             *

             * 滑动状态发生改变的状态

             */

            @Override

            public void onPageScrollStateChanged(int position) {

            }

        });

    }

    private List<ImageView> initData() {

        List<ImageView> imageViewsList = new ArrayList<ImageView>();

        // 加入图片控件

        ImageView imageView1 = new ImageView(getApplicationContext());

        imageView1.setBackgroundResource(R.drawable.guide_image1);

        ImageView imageView2 = new ImageView(getApplicationContext());

        imageView2.setBackgroundResource(R.drawable.guide_image2);

        ImageView imageView3 = new ImageView(getApplicationContext());

        imageView3.setBackgroundResource(R.drawable.guide_image3);

        imageViewsList.add(imageView1);

        imageViewsList.add(imageView2);

        imageViewsList.add(imageView3);

        return imageViewsList;

    }

}

当中的适配器例如以下：

package com.xlg.news.adapters;

import java.util.List;

import android.content.Context;

import android.support.v4.view.PagerAdapter;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ImageView;

/**

 * 第一次启动页面的ViewPager适配器

 * @author xuliugen

 */

public class WelcomeViewPagerAdapter extends PagerAdapter {

    private Context mContext;

    private List<ImageView> mImageViewsList;

    public WelcomeViewPagerAdapter(Context context,

            List<ImageView> imageViewsList) {

        mContext = context;

        mImageViewsList = imageViewsList;

    }

    @Override

    public int getCount() {

        return mImageViewsList.size();

    }

    @Override

    public boolean isViewFromObject(View view, Object object) {

        return view == object;

    }

    /**

     * 给制定的viewpager加入一个view的方法

     */

    @Override

    public Object instantiateItem(ViewGroup container, int position) {

        //加入一个imageView

        container.addView(mImageViewsList.get(position));

        return mImageViewsList.get(position);

    }

    /**

     * 给制定的viewpager移除一个view的方法

     */

    @Override

    public void destroyItem(ViewGroup container, int position, Object object) {

        container.removeView((View)object);

    }

}
