这个效果在交友app中比较常见，一般作为首页使用，顶部是一个自动轮播的ViewPager，下面放一个横向LinearLayout，最下面要放一个ListView，但是注意这三个部分都支持滑动，应该和固定在顶部的标题栏和底部的操作栏分开，也就是把ViewPager和LinearLayout以及ListView都放在父控件ScrollView里面

主窗口代码：

public class IndexActivity extends AppCompatActivity implements View.OnClickListener{

  private Context mContext;
  private List<Integer> mImageList;
  private List<Candidate> mCandidateList;
  private ViewPagerAdapter mPagerAdapter;
  private CandidateListAdapter mListAdapter;

  @SuppressLint("HandlerLeak")
  private Handler handler = new Handler() {

    @Override
    public void handleMessage(Message msg) {
      //每次将当前的位置加1，也就是向右滑动一次
      vp.setCurrentItem(vp.getCurrentItem() + 1);
      //递归无限循环调用
      handler.sendEmptyMessageDelayed(0x123, 2000);
    }
  };

  @Override
  protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_index);
    ButterKnife.bind(this);

    initData();
    initView();
    intListener();
  }

  //初始化数据源，固定写法 1.实例化容器 2.实例化适配器 3.设置适配器
  private void initData() {
    mContext = this;
    mImageList = new ArrayList<>();
    mCandidateList = new ArrayList<>();
    mListAdapter = new CandidateListAdapter(mCandidateList);
    mPagerAdapter = new ViewPagerAdapter(mImageList);
    lvfsv.setAdapter(mListAdapter);
    vp.setAdapter(mPagerAdapter);

    getListData(10);
    getPagerData();

    //间隔2秒发送一次信息
    handler.sendEmptyMessageDelayed(0x123, 2000);
  }

  //生成ViewPager数据源
  private void getPagerData() {
    mImageList.add(R.drawable.bm1);
    mImageList.add(R.drawable.bm2);
    mImageList.add(R.drawable.bm3);
    mImageList.add(R.drawable.bm4);
    mImageList.add(R.drawable.bm5);
    mImageList.add(R.drawable.bm6);

    mPagerAdapter.notifyDataSetChanged();
    //初始的位置在正中间
    vp.setCurrentItem(mPagerAdapter.getCount() / 2);
  }

  //生成ListView数据源
  private void getListData(int num) {
    for (int i = 0; i < num; i++) {
      Candidate candidate = new Candidate();
      candidate.setName("姓名:尼尔斯·亨利克·戴维·玻尔");
      candidate.setInfo("职业:学者,物理学家,足球运动员");
      candidate.setTrait("成就:哥本哈根学派的创始人,1922年获得诺贝尔物理学奖");
      mCandidateList.add(candidate);
    }

    mListAdapter.notifyDataSetChanged();
  }

  private void initView() {
    tvTitleMiddle.setText("轮播列表");
    //手动设置ScrollView的位置
    scrollView.smoothScrollTo(0, 0);
  }

  //初始化监听
  private void intListener() {
    mPagerAdapter.setmCallback((v, position) -> {
      Toast.makeText(mContext, "position: " + position, Toast.LENGTH_SHORT).show();
    });

    lvfsv.setOnItemClickListener((parent, view, position, id) -> {
      Toast.makeText(mContext, "position: " + position, Toast.LENGTH_SHORT).show();
    });

    for (int i = 0; i < 4; i++) {
      ivs.getChildAt(i).setOnClickListener(this);
    }
  }

  @Override
  public void onClick(View v) {

    switch (v.getId()){
      case R.id.iv1:
      case R.id.iv2:
      case R.id.iv3:
      case R.id.iv4:
        Toast.makeText(mContext, "此处跳转", Toast.LENGTH_SHORT).show();
    }
  }
}

ListView需要覆盖onMeasure方法，代码如下：

public class ListViewForScrollView extends ListView {
  public ListViewForScrollView(Context context) {
    super(context);
  }
  public ListViewForScrollView(Context context, AttributeSet attrs) {
    super(context, attrs);
  }
  public ListViewForScrollView(Context context, AttributeSet attrs,
    int defStyle) {
    super(context, attrs, defStyle);
  }
  @Override
  /**
   * 重写该方法，达到使ListView适应ScrollView的效果
   */
  protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
    MeasureSpec.AT_MOST);
    super.onMeasure(widthMeasureSpec, expandSpec);
  }
}

ViewPager适配器代码：

public class ViewPagerAdapter extends PagerAdapter implements View.OnClickListener {

  //图片的资源id列表
  private List<Integer> mList;
  private Callback mCallback;

  public ViewPagerAdapter(List<Integer> mList) {
    this.mList = mList;
  }

  public void setmCallback(Callback mCallback) {
    this.mCallback = mCallback;
  }

  public interface Callback {
    void onClick(View v, int position);
  }

  @Override
  //将适配器中的数据设为无穷大
  public int getCount() {
    return Integer.MAX_VALUE;
  }

  @Override
  //固定写法，不覆盖会报错
  public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {
    container.removeView((View) object);
  }

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

  @NonNull
  @Override
  public Object instantiateItem(@NonNull ViewGroup container, int position) {
    LayoutInflater inflater = LayoutInflater.from(container.getContext());
    ImageView imageView = (ImageView) inflater.inflate(R.layout.item_image_pager, null);

    //将position转换成余数
    int realPosition = position % mList.size();
    imageView.setImageResource(mList.get(realPosition));
    imageView.setOnClickListener(this);
    //tag放跳转需要的数据
    imageView.setTag(realPosition);
    //将实例加入父控件
    container.addView(imageView);
    return imageView;
  }

  @Override
  //使用接口将position回传
  public void onClick(View v) {
    mCallback.onClick(v, (int) v.getTag());
  }
}

大功告成，实现效果如下：
