Android ScrollView滚动距离和判断滚动停止状态

由 人走茶凉 提交于 2019-12-20 04:57:29
因为ScrollView没有像listView中的setOnScrollListener()监听，当然也就没有SCROLL_STATE_IDLE等。 解决的问题： 公司项目需要在一个列表中，类似listView,因为业务要求，这个列表是用拼凑的方法，拼凑出来的，所以外层包裹一层ScrollView。 现在公司要求，滑动到最后一条的时候，加载下一部分数据。如果使用scrollView.getScrollY()获得的是你手滑动的距离，当你松开手之后，界面会继续滑动，这个方法是获取不到新的Y值，所以，我们可以添加监听，时刻监视着ScrollView的变化。 需要先给ScrollView添加TouchListener ,在MotionEVENT.Up中，发送延迟的handler,这样就可以起到监听的作用。并且记录当前的高度lastY 在handler中，如果高度lastY和scrollView.getScrollY()是相等的，则表示，ScrollView已经停止，这时再根据你的要求判断停止之后的业务。这时的scrollView.getScrollY()就是控件滚动的距离。如果不相等，证明孩子啊滑动中，继续发handler继续记录lastY。 废话不多说，代码如下。希望对你有所帮助。 vBookDetail.setOnTouchListener(new OnTouchListener()

Why are fading edges slow?

问题 As noted in this answer, fading edges in ScrollView s can be slow. I want to know, why? "Using fading edges may introduce noticeable performance degradations and should be used only when required by the application's visual design. To request fading edges with API level 14 and above, use the android:requiresFadingEdge attribute instead" http://developer.android.com/reference/android/R.attr.html#fadingEdge My interest is motivated by two things: Wanting to use fading edges to provide a visual

iOS setContentOffset not working on ipad

由 吃可爱长大的小学妹 提交于 2019-12-20 03:27:03
问题 This is really strange. I have a scrollview that contains a three images, and the user swipes to see the next image. However, I want the first screen to start at the middle image. Easy; I'll use setContentOffset and all will be fine. The code works on the iPhone simulator, but not on the iPad simulator (or device!) CGRect screen = [[UIScreen mainScreen] bounds]; CGFloat height = CGRectGetHeight(screen); CGFloat width = CGRectGetWidth(screen); CGPoint rightOffset = CGPointMake(width, 0);

问题 I have a TextInput inside a ScrollView. The scroll isn't working when the TextInput is on focus. This problem is only affecting Android. 回答1: setting <ScrollView keyboardShouldPersistTaps="always" in combination with the textInout component below (custom component that i created for text inputs to solve this issue) solved my problem: <TouchableOpacity activeOpacity={1} onPress={()=>this.input.focus()}> <View pointerEvents="none" <TextInput ref = {(input) => this.input = input} /> </View> <
