I found a very simple solution for this. Just get the adapter of the listview and calculate its size when all items are shown. The advantage is that this solution also works inside a ScrollView. Example: public static void justifyListViewHeightBasedOnChildren (ListView listView) { ListAdapter adapter = listView.getAdapter(); if (adapter == null) { return; } ViewGroup … Read more
There are a few solutions that already exist for this problem. What you’re describing are section headers and have come to be referred to as sticky section headers in Android. Sticky List Headers Sticky Scroll Views HeaderListView
You can simply use SliverToBoxAdapter : SliverToBoxAdapter( child: Container(..), )
You can use android:fillViewport=”true” to center the content. Something like this: <ScrollView xmlns:android=”http://schemas.android.com/apk/res/android” android:layout_width=”match_parent” android:layout_height=”match_parent” android:fillViewport=”true”> <!– content –> </ScrollView>
The simple answer is just to replace scrollView.smoothScrollTo(0, scrollTo); with ObjectAnimator.ofInt(scrollView, “scrollY”, scrollTo).setDuration(duration).start(); where duration is the time in milliseconds you want it to take.
To always have the scroll enabled on a ListView you can wrap the original scroll phisics you want with the AlwaysScrollableScrollPhysics class. More details here. If you want you can specify a parent or rely on the default. Here is your example with the option added: import ‘package:flutter/material.dart’; void main() => runApp(new MyApp()); class MyApp … Read more
Try this: @Override protected void onScrollChanged(int l, int t, int oldl, int oldt) { // Grab the last child placed in the ScrollView, we need it to determinate the bottom position. View view = (View) getChildAt(getChildCount()-1); // Calculate the scrolldiff int diff = (view.getBottom()-(getHeight()+getScrollY())); // if diff is zero, then the bottom has been reached … Read more
This is being caused because of the layout_gravity in your LinearLayout. Since your LinearLayout is inside a ScrollView you are probably just trying to center horizontally (centering vertically inside a ScrollView doesn’t make since). Specifying your LinearLayout to center horizontally like this should do the trick: <LinearLayout android:layout_width=”fill_parent” android:layout_height=”wrap_content” android:orientation=”vertical” android:layout_gravity=”center_horizontal” android:padding=”10dip” >
You can vertically center content in a scroll view by using GeometryReader to get the parent view’s dimensions and setting the scroll view’s content’s minHeight to the parent’s height. When the content is too big to fit vertically it’ll just scroll like normal. For example: var body: some View { GeometryReader { geometry in // … Read more
Just created and tested it. Looks like you want. <?xml version=”1.0″ encoding=”utf-8″?> <RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android” android:layout_width=”match_parent” android:layout_height=”match_parent”> <LinearLayout android:id=”@+id/buttons” android:layout_width=”match_parent” android:layout_height=”wrap_content” android:orientation=”horizontal” android:gravity=”center” android:layout_alignParentBottom=”true”> <Button android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:text=”Custom Button1″/> <Button android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:text=”Custom Button2″/> </LinearLayout> <ScrollView android:layout_width=”match_parent” android:layout_height=”match_parent” android:layout_above=”@id/buttons”> <!–Scrollable content here–> <LinearLayout android:layout_width=”match_parent” android:layout_height=”wrap_content” android:orientation=”vertical”> <TextView android:layout_height=”wrap_content” android:layout_width=”wrap_content” android:text=”test text” android:textSize=”40dp”/> </LinearLayout> </ScrollView> </RelativeLayout>
