GIF图片：

主屏幕是我的HomeFragment，在其中我使用CollapsingToolbarLayout，NestedScrollView和ViewPager，并且在ViewPager中，下面是Load 3 Fragments代码

private void setupViewPager(ViewPager viewPager) {
        HomeFragment.ViewPagerAdapter adapter = new HomeFragment.ViewPagerAdapter(getChildFragmentManager());
        adapter.addFragment(new InstantFragment(), "Instant");
        adapter.addFragment(new LimitFragment(), "Limit");
        adapter.addFragment(new StopFragment(), "Stop");
        viewPager.setAdapter(adapter);
    }

这是我的 fragment_home.xml 代码

这是CustomViewPager

的代码

public class CustomViewPager extends ViewPager {
public CustomViewPager(Context context) {
    super(context);
}

public CustomViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);

    int height = 0;
    for (int i = 0; i < getChildCount(); i++) {
        View child = getChildAt(i);
        child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
        int h = child.getMeasuredHeight();
        if (h > height) height = h;
    }
    heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
