scrollview

问题 Looking at this solution for a better autoscroll I thought myself to be so clever to find an easier solution, but it works only in a debug session: private void scrollviewer_Messages_ScrollChanged(object sender, ScrollChangedEventArgs e) { ScrollViewer sv = sender as ScrollViewer; if (sv.VerticalOffset == sv.ScrollableHeight) { sv.ScrollToEnd();//debug breakpoint } return; } While adding content to the textblock in this ScrollViewer, autoscroll works, the bottom of the text stays in view.

问题 How can i detect how much a scroll view has scrolled ? 回答1: You need to override the onScrollChanged() method of the ScrollView: @Override protected void onScrollChanged(int l, int t, int oldl, int oldt) { Log.i(TAG, "View onScrollChanged"); View view = (View) getChildAt(getChildCount() - 1); int diff = (view.getBottom() - (getHeight() + getScrollY()));// Calculate super.onScrollChanged(l, t, oldl, oldt); } Here, diff is the space left for scrolling between the bottom edge of the ScrollView ,

问题 Here is what I would like my ScrollView to look like: The maximum size is defined with the layout_weight (so that other items below the ScrollView can be displayed properly) If the content is smaller than that maximum size, then it just behaves as with layout_height="wrap_content" Here is what I currently have: <ScrollView android:layout_height="wrap_content" android:layout_width="fill_parent" android:measureAllChildren="true" android:fillViewport="false" > I don't think the

问题 I mean that i want to get rid of the "end of scrolling indicator" that appears when the user try to overscroll the view: 回答1: never mind, i've found a neat feature called android:overScrollMode="never". that did the trick :D 来源： https://stackoverflow.com/questions/32172868/android-disable-horizontalscrollview-end-of-scrolling-edge

问题 Our app (WordPress for Android) uses a scrollview for the new post view, where a user enters in their new blog post. There's quite a few fields on this view, including a large EditText for the post content field. It appears that when an EditText is in a ScrollView, the ScrollView takes over the scrolling action, so the user can't scroll within the EditText area if they are writing a large post. What can be done so that scrolling will work both within the EditText and the ScrollView? Here is

问题 It should be easy I know!!! I watched tutorial, searched for approx. 2 hours and tried like 15 different methods (maybe more) and still can't get it to work.

问题 We have a Xamarin.Android 7 app. We are getting the following exception which causes the app to crash. It says something about Android.Widget.Scroller, but we are not using this component explicitly in our app anywhere. We are using ScrollView and GridView in xaml files though. One solution which we came across was to move back to Xamarin.Android 6, but that is not a feasible solution due to app requirements. One more solution we came across was to use ListViewCachingStrategy, but couldn't

问题 I am currently working on an application in which I have to taken into account two ListViews one above another and that too with a common scroll. I know this is not the best practice, instead I should have taken just a single ListView but the problem is with the layouts that doesn't seem to be possible with a sinlge ListView. Actually my first ListView will contain list of friend requests that I can accept or ignore and that are not static and can vary with no limit and second list will
