在xml中写好布局

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

在activity中定义

private ViewPager viewpager;
viewpager = findView(R.id.viewpager);

设置监听

viewpager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

            }

            @Override
            public void onPageSelected(int position) {
                if (position == 2) {
                    tvGuideSkip.setVisibility(View.GONE);
                    btnGuideEnter.setVisibility(View.VISIBLE);
                } else {
                    tvGuideSkip.setVisibility(View.VISIBLE);
                    btnGuideEnter.setVisibility(View.GONE);
                }
            }

            @Override
            public void onPageScrollStateChanged(int state) {

            }
        });

ViewPager与layout.xml

新建Adapter 继承PagerAdapter

public class ViewPagerAdapter extends PagerAdapter {

    private ArrayList<View> views;

    public ViewPagerAdapter(ArrayList<View> views) {
        super();
        this.views = views;
    }

    @Override
    public int getCount() {
        return views.size();
    }

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

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        container.addView(views.get(position));
        return views.get(position);
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView(views.get(position));
    }
}

在activity中使用

public class GuideActivity extends BaseActivity implements View.OnClickListener {
    private ArrayList<View> viewList;
    private ViewPager viewpager;
    private TextView tvGuideSkip;
    private Button btnGuideEnter;

    @Override
    public void setStatusBar() {
        super.setStatusBar();
        StatusBarUtil.setTransparent(this);
    }

    @Override
    public int getLayoutId() {
        return R.layout.start_activity_guide;
    }

    @Override
    public void initData() {
        viewList = new ArrayList<>();
        viewList.add(View.inflate(this, R.layout.start_guide_one, null));
        viewList.add(View.inflate(this, R.layout.start_guide_two, null));
        viewList.add(View.inflate(this, R.layout.start_guide_three, null));
    }

    @Override
    public void initView() {
        viewpager = findView(R.id.viewpager);
        tvGuideSkip = findView(R.id.tv_guide_skip);
        btnGuideEnter = findView(R.id.btn_guide_enter);
        viewpager.setAdapter(new ViewPagerAdapter(viewList));
    }

    @Override
    public void initListener() {
        tvGuideSkip.setOnClickListener(this);
        btnGuideEnter.setOnClickListener(this);
        viewpager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

            }

            @Override
            public void onPageSelected(int position) {
                if (position == 2) {
                    tvGuideSkip.setVisibility(View.GONE);
                    btnGuideEnter.setVisibility(View.VISIBLE);
                } else {
                    tvGuideSkip.setVisibility(View.VISIBLE);
                    btnGuideEnter.setVisibility(View.GONE);
                }
            }

            @Override
            public void onPageScrollStateChanged(int state) {

            }
        });
    }

    @Override
    public void viewsClick(View view) {
        int i = view.getId();
        if (i == R.id.tv_guide_skip) {
            CC.obtainBuilder("ComponentHome").setActionName("HomeActivity").build().call();

        } else if (i == R.id.btn_guide_enter) {
            CC.obtainBuilder("ComponentHome").setActionName("HomeActivity").build().call();

        }
    }

}
