我是 android 开发的新手。我遇到了一些未知类型的情况，我的可扩展列表视图没有显示。在添加 scoolview 之前，它对我来说非常有用。

这里是我的 MainActivity.xml:-

我尝试了很多东西，但找不到正确的解决方案。请帮帮我！

【问题讨论】：

  • 你想要ExpandableListView 和ScrollView 在NavigationDrawer 中，你想达到什么目的？
  • 没有在导航抽屉中我只想要 ExpandableListView
  • 好的，那么你想要ScrollView/
  • 我想在主页显示滚动视图
  • 然后尝试在FrameLayout 中添加ScrollView

【解决方案1】：

请试试这个，这可能对你有帮助... 当 U r Setting adapter 正下方调用此方法时...

public static void setListViewHeightBasedOnChildren(ListView listView) {
        ListAdapter listAdapter = listView.getAdapter();
        if (listAdapter == null)
            return;

        int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.UNSPECIFIED);
        int totalHeight = 0;
        View view = null;
        for (int i = 0; i < listAdapter.getCount(); i++) {
            view = listAdapter.getView(i, view, listView);
            if (i == 0)
                view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth, ViewGroup.LayoutParams.WRAP_CONTENT));

            view.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
            totalHeight += view.getMeasuredHeight();
        }
        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
        listView.setLayoutParams(params);
        listView.requestLayout();
    }

    试试这个，重新排列滚动视图和展开列表视图的布局位置
