Android: Detect when ScrollView has finished scrolling and bouncing back?

由 馋奶兔 提交于 2019-12-21 01:19:08
问题 I have a ScrollView which has two hidden images, one at the top and one at the bottom. In between there is a bunch of visible content. What I need to do is make these images hidden by default but when you scroll all the way up or all the way down you could see them as you're scrolling. But then as soon as you stop scrolling it should bounce back to the visible area so that the hidden images aren't showing. Basically I'm trying to imitate the bounce scrolling feature of the iphone UIScrollView

Unable to find reason for Crash on -[UIScrollView(UIScrollViewInternal) _scrollViewAnimationEnded:finished:]

问题 In my app many crashes with the following log are reported very often, but even with several test devices and iOS versions I am not able to reproduce it. So there's no way to find the reason on Xcode. Because there's no step in the trace, that leads to my code, I cannot imagine any way to find the origin of it. The App itself is very complex and of course many Scroll Views, also embedded, are used. Has anyone an idea where to start looking? Or has anyone had a similar problem before? I'm very

上拉查看详情和下拉隐藏详情

由 我是研究僧i 提交于 2019-12-20 10:27:16
https://blog.csdn.net/liuzonrze/article/details/71409544 项目商品详情页的需求，实现上拉显示和下拉隐藏详情的功能，最终效果图如图： 实现思路：上下通过判断两个ScrollView的滑动位置及触摸事件发生的位置，对他们进行隐藏和显示。 上拉部分，由于内部包裹了大量带有点击事件的组件，故需要在上拉条上进行拖动，否则会冲突无法判断。这部分是通过对其包裹内容动态的调用layout方法来实现拖拽效果； 下拉部分，通过对下拉头动态设置marginTop的值，来改变其高度，并达到隐藏和显示的效果。 核心代码 //上拉组件 @Bind(R.id.xscrollview) XScrollView mXscrollview; @Bind(R.id.scrollContainer) LinearLayout scrollContainer; //下拉组件 @Bind(R.id.scrollContainer2) RelativeLayout scrollContainer2; @Bind(R.id.svBottomDetails) ScrollView svBottomDetails; @Bind({R.id.llDownScroll}) LinearLayout llDownScroll; //上拉部分 private Rect rect =

React Native Touchable is disabling ScrollView

问题 I'm new to React Native, so am probably asking something very obvious, but please help. I have a view wrapped in a touchable, so that the whole area responds to tapping. Then have a ScrollView nested inside the view. The overall structure is something like this: <TouchableWithoutFeedback onPress={this.handlePress.bind(this)}> <View> <ScrollView> <Text>Hello, here is a very long text that needs scrolling.</Text> <ScrollView> </View> </TouchableWithoutFeedback> When this compiles and runs, the

Android - ScrollView like foursquare with maps + list

由 五迷三道 提交于 2019-12-20 08:55:08
问题 This is the Android equivalent of this iOS question. Trying to create a view that contains a MapView at about 20% of the screen (under an ActionBar...) and the rest of the screen is a ScrollView that when scrolling down, overlaps on top of the MapView and hides it. In short like FourSquare's Android app. Any ideas? 回答1: I've made an implementation based on AndroidSlidingUpPanel (many thanks to this project).
