首先我不熟悉CoordinatorLayouts,我有一个包含几个可滚动的CardViews的片段,当我尝试添加底部工作表时,我得到了底部工作表必须是一个CoordinatorLayout的孩子错误,所以我添加了一个coordinatorLayout,现在我似乎无法滚动了
PS:我尝试用ScrollView
替换NestedScrollView
并且它不起作用,我甚至尝试编辑XML标记顺序,但没有解决它,我仍然无法滚动
我是否可以使用Bottom Sheets
而无需使用CoordinatorLayout
这是使用ScrollView的XML布局片段:
<android.support.design.widget.CoordinatorLayout

<ScrollView

以下是使用NestedScrollView的XML布局片段:

答案 0 :(得分:1)
编辑:从片段中删除BottomSheetLayout,并将其放在ViewPager下的Activity中。然后在片段顶部放置一个NestedScrollView
,其属性如下:
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:fillViewport="true">
要使BottomSheet仅出现在片段中,您可以这样做:
将可见性设置为android:visiblity="gone"
,并在片段中将其设置为visibile,如下所示:
var sheet = (View)getActivity().findViewById(R.id.{sheet});
sheet.setVisbility(view.Visible);
然后,在其他片段中,使用sheet.setVisbility(view.Gone);
要在按下背面时隐藏它,请在活动:
中使用此功能 @Override
public void onBackPressed() {
if (sheet.getVisibility() == View.VISIBLE) {
sheet.setVisbility(view.Gone);
}
