scrollview

问题 I have an activity that has a ScrollView with a vertical LinearLayout that has two fragments that are PreferenceFragment instances as shown in the following layout file: <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_height="wrap_content" android:layout_width="match_parent" > <LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:layout_height="wrap_content" tools:context=

问题 I know about this command: self.tableView.scrollEnabled = true The question is: I want to lock scrolling according to the scrollView position. For this I do: let topEdge = scrollView.contentOffset.y let followersViewEdge = CGRectGetHeight(self.profileView.frame) - 50 if topEdge >= followersViewEdge { self.tableView.scrollEnabled = true } it works, but the problem is that it does not lock or unlock the scrolling immediately. For locking or unlocking the UITableView scrolling I need to release

问题 I am trying to create a layout with a header, a banner below it, and then a couple of ListView under the banner. I want the the complete screen to be scrollable except the header. Now I know that ListView does not scroll within a ScrollView so I have set the height of the ListView big enough to show all the items. The problem is that, even after these changes, I see that the ListView is scrolling independently and the complete screen is not scrollable. ` <include android:id="@+id/logo_header"

问题 this is the example XML <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:layout_margin="5dip" android:background="#FF992222"> <ScrollView android:layout_height="wrap_content" android:layout_width="fill

问题 Got a LinearLayout containing a textview and an edittext. The LinearLayout is inside a ScrollView. The ScrollView is inside another view hierarchy (part of a Work Space layout, like the Android Homescreen kinda), but this fills parent, both height and width (I set fill color different to check this). With attributes of fill_parent for layout_height and layout_width on the LinearLayout though, it's only filling the parent width-ways, not height. Setting the height to fixed also doesn't work/

问题 In my application, i'm using the following code for holding a map which is downloaded from a server. <?xml version="1.0" encoding="utf-8"?> <ScrollView android:id="@+id/scrollView1" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_gravity="center" android:layout_weight="1.0"> <ImageView android:id="@+id/mapImageView" android:layout_height="wrap_content" android:layout_centerInParent="true" android:layout_width="wrap_content" android:scaleType="center"/> <

问题 I'm new to flutter and I'm not able to achieve the layout I want. I have one sliverAppBar with 3 tabs. The content of one of the tabs has to be a ScrollView compound by one container with fixed size(with an image as background) and a ListView. I've tried to do this with a CustomScrollView but I don't know how to create the container as it is not a sliver. Can you point me in the right direction? Regards, Diego. 回答1: You can simply use - SliverToBoxAdapter( child: Container(..) 来源： https:/

问题 I want some of the goodies in a ListView, like being able to use a ListAdapter, and item selection, etc, but I don't want the ScrollView portion of it. I want to implement that part myself, in a different way (why or how I do this isn't really the point of this question, so please don't ask "why"). Is there a way to have a ListView that's not in a ScrollView or has the scrolling disabled? 回答1: A ListView is not in a ScrollView . A ListView does scrolling instrinsically. I do not believe you
