【问题描述】：

问题是 viewpager 可以工作，但 scrollview 不能。 ListView 以异步方式填充，也许这是问题，因此没有正确测量布局。无论如何，这是片段的布局（viewpager 有两个选项卡，这是第二个选项卡的内容：

    <ScrollView

【问题讨论】：

  • 参考这个解决方案：- stackoverflow.com/a/44017731/3946958
  • 用 NestedScrollView 替换滚动视图
  • 没有帮助，我现在可以查看所有内容，除了我的列表视图现在只有一项而不是四项。也许我不能拥有位于 insideviewpager 的nestedscrollview 内的列表视图？
  • 在嵌套滚动视图和列表视图中添加 app:layout_behavior="@string/appbar_scrolling_view_behavior"
  • 和以前一样……

【解决方案1】：

这是解决方案。放置 NestedScrollView 在某种程度上肯定有帮助，但 ListView 只显示一个项目，而其他项目只有在我滚动那一小块 UI（listview）时才可见。所以我决定制作不可滚动的列表视图（因为我想显示它们并且嵌套滚动视图将滚动整个片段）。这是 NonScrollableListView 的代码：

public class NonScrollListView extends ListView {

    public NonScrollListView(Context context) {
        super(context);
    }
    public NonScrollListView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    public NonScrollListView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }
    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
                Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
        ViewGroup.LayoutParams params = getLayoutParams();
        params.height = getMeasuredHeight();
    }
}

现在列表视图显示所有元素，并且由于 NestedScrollView，片段也是可滚动的。

    【解决方案2】：

    不要在ScrollView 中使用ListView。使用android.support.v4.widget.NestedScrollView 使其工作。

    试试这个：
