我在片段和活动中有一个 NestedScrollview 作为具有折叠工具栏的父级，使用 viewpager，问题是嵌套的滚动视图不会滚动以显示完整的 UI，除非我显示 textinputlayout 错误，

在 textinput 布局出现错误后，视图（按钮）显示活动布局如下，

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

    </android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>

viewpager 和 scrollivew 的样式，没有 true 从来没有

这是我的注册屏幕的布局，在 NestedScrollview 里面没有滚动到它的全长，直到 textinputlayout 显示错误，附上截图以供参考&布局如下，

您可以使用 MyMeasuredViewPager 并使用它来代替您的视图寻呼机

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

    public MyMeasuredViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }


    @Override
    protected void onMeasure(int widthMeasureSpec, int 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);
    }
}
