能否动态获取recyclerview的内容高度

Expected Behavior

Actual Behavior

Steps to Reproduce the Problem

RecyclerViewHelper.java中getScrollRange中是通过mView.getPaddingTop() + itemCount * itemHeight + mView.getPaddingBottom();来计算ScrollRange，但是我们实际使用中用到了ConcatAdapter，就是同一个recyclerview中，有多种adapter，每种adapter中，列数是不一样的，而且itemView的高度也是不一样的，所以getScrollRange的计算方法不适用我们这种场景。请问一下有什么比较好的解决方法吗？另外，是否有考虑过通过mView.computeVerticalScrollRange()来代替itemCount * itemHeight吗（我这么试过，但是发现算出来的值不是固定的，滑动到底的时候，数值会变化）

Specifications

Version:
Platform:

PopupTextProvider#getPopupText(int position) should be @Nullable

The interface PopupTextProvider:

@NonNull <=====
String getPopupText(int position);

But RecyclerViewHelper#getPopupText() accepts that getPopupText(int position) can return null.
i.e. that there is no popup text for that position.

Can I kindly propose you change the interface to

@Nullable <=====
String getPopupText(int position);

Android Studio's error reporting and myself would be grateful :)

Change Md2PopupBackground class modifier

I want to custom PopupStyles MD2 textColor is white color in Kotlin (1.3.50). But currently, I can't access Md2PopupBackground because it missing modifier public . Can you make it is public or support a PopupStyles.Builder that allow custom somethings as textColor, backgroundColor...

Cannot access 'Md2PopupBackground': it is public/package/ in 'me.zhanghai.android.fastscroll'

Thanks!

在 Android 10 及 Android 11 上会闪退？

在 Android 10 及 Android 11 上会闪退，闪退日志很奇怪，说是“JNI DETECTED ERROR IN APPLICATION ... java.lang.IllegalStateException: Unable to create layer for View ... ”，分析很久也找不出原因，最后去掉FastScroll的调用才不闪退。

使用这个方案在 Android 10 及 Android 11 上是正常的：https://github.com/Mixiaoxiao/FastScroll-Everywhere

FixItemDecorationRecyclerView crashes in runtime

If you try to use FixItemDecorationRecyclerView this will definitely crash with ClassCastException in runtime.
As you can see in the source code:

@Override
    protected void dispatchDraw(@NonNull Canvas canvas) {
        for (int i = 0, count = getItemDecorationCount(); i < count; ++i) {
            FixItemDecoration decor = (FixItemDecoration) getItemDecorationAt(i);
            decor.getItemDecoration().onDraw(canvas, this, decor.getState());
        }
        super.dispatchDraw(canvas);
        for (int i = 0, count = getItemDecorationCount(); i < count; ++i) {
            FixItemDecoration decor = (FixItemDecoration) getItemDecorationAt(i);
            decor.getItemDecoration().onDrawOver(canvas, this, decor.getState());
        }
    }

    @Override
    public void addItemDecoration(@NonNull ItemDecoration decor, int index) {
        super.addItemDecoration(new FixItemDecoration(decor), index);
    }

    @NonNull
    @Override
    public ItemDecoration getItemDecorationAt(int index) {
        return ((FixItemDecoration) super.getItemDecorationAt(index)).getItemDecoration();
    }

You wrap ItemDecorations into FixItemDecoration (see addItemDecoration method) and then you cast it in such a way FixItemDecoration decor = (FixItemDecoration) getItemDecorationAt(i); (see dispatchDraw method)

Please fix this.

Expose methods to adjust mMinTouchTargetSize in FastScroller

Hello, I noticed that the FastScroller class in your library does not provide getter and setter methods to modify the mMinTouchTargetSize property. Moreover, it is not possible to set this value through the constructor. By default, the value is set to 48dp (<dimen name="afs_min_touch_target_size">48dp</dimen>), which may not work correctly for different screen sizes and densities.

It would be beneficial to expose methods to adjust the mMinTouchTargetSize property, allowing developers to fine-tune this value for their specific use cases and ensure a better user experience across various devices.

Possible solution:

Add getter and setter methods for mMinTouchTargetSize in the FastScroller class.
Alternatively, allow passing this value through the constructor or FastScrollerBuilder class.

This improvement would provide better customization options and ensure the library's adaptability to different screen configurations.

Thank you for your attention to this issue, and I appreciate your work on this library.

Support scrollbar location override instead of using view layout direction

Expected Behavior

Feature motivation...

I have a left-handed user that would like the scrollbar on the left hand side, even when the text and layouts are in LTR mode.

Ideally, some sort of setting on the FastScrollerBuilder that would eventually cause the onPreDraw to use this override instead view.getLayoutDirection.

Actual Behavior

Steps to Reproduce the Problem

Specifications

Version: 1.1.4
Platform: Android

Is it posible to activate fastscrolling only on thumb click, not the entire track?

Expected Behavior

You click thumb, it has current behaviour. You click the track outside of thumb and it does not react. One of the examples of expected behavior could be Google Photos fast track.

Actual Behavior

Thumb follows your click in any track area.

Conflict with ItemTouchHelper

Expected Behavior

There's no conflict.

Actual Behavior

When scrolling, item dragging will also be triggered.

Unwanted visualize effect + jumpy effect when applying AndroidFastScroll on RecyclerView

Hi Zhang Hai,

I am currently using 1.1.7

I can appreciate your library over AndroidX's RecyclerView's app:fastScrollEnabled implementation due to

Your library provide a wider touch region for thumb. Hence, it is easier to hit rect the thumb.
Your library will make the touch point stay correctly on thumb. For instance, if we touch on the vertical center of the thumb. After fast scrolling, our touch point will remain on the center of thumb.

The following is the AndroidX's implementation, which doesn't respect the initial touch point of thumb - https://www.youtube.com/watch?v=c9jkI7ryyoA In AndroidX's example, our initial touch point is the center of the thumb. However, after fast scrolling, our touch point will no longer stay at the center of thumb

Here's the AndroidX's implementation

app:fastScrollEnabled="true"
app:fastScrollVerticalThumbDrawable="@drawable/fast_scroll_thumb_material_light"
app:fastScrollVerticalTrackDrawable="@drawable/fast_scroll_track_material_light"
app:fastScrollHorizontalThumbDrawable="@drawable/fast_scroll_thumb_material_light"
app:fastScrollHorizontalTrackDrawable="@drawable/fast_scroll_track_material_light"

When I port to your library, I am happy to see it

Respect initial touch point of the thumb
Provide wider touch region

However, it does yield some behaviour, which is previously not seen in AndroidX

When scroll to the top most, the scroll bar will disappear. When scroll to the bottom most, there is an unwanted padding - https://www.youtube.com/watch?v=veIfuR9eUrk
After scroll to the top most and scroll bar disappear, scroll again will produce "jumpy" effect - https://youtu.be/BmJF2nRsGiE

I am using the exact same RecylerView configuration as when I use AndroidX

I do not have any bottom padding, or top padding on the RecyclerView itself.

This is my RecyclerView

<androidx.recyclerview.widget.RecyclerView
    
    android:requiresFadingEdge="none"
    android:scrollbars="none"

    android:background="?attr/recyclerViewBackground"
    android:id="@+id/recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clipToPadding="false"
    android:paddingTop="0dp"
    android:paddingBottom="0dp" />

and this is the new code I have added

FastScrollerBuilder fastScrollerBuilder = new FastScrollerBuilder(recyclerView);
fastScrollerBuilder.setThumbDrawable(getResources().getDrawable(R.drawable.fast_scroll_thumb_material_light));
fastScrollerBuilder.setTrackDrawable(getResources().getDrawable(R.drawable.fast_scroll_track_material_light));
fastScrollerBuilder.build();

Do you have an idea what might go wrong, and where I can start to debug from?

Thank you very much!

p/s I just realize I am using your materialratingbar library too when I adding your AndroidFastScroll into build.gradle. Thank you!

Add method to check if FastScroller is currently being displayed

Hello, I would like to request the addition of a method in the FastScroller class that allows developers to determine if the fast scroll is currently being displayed. This feature would be helpful in various scenarios where the visibility status of the fast scroll might be needed to adapt the UI or handle specific user interactions.

Suggested implementation:
Please consider adding a method, such as isFastScrollVisible, to the FastScroller class that returns a boolean value indicating whether the fast scroll is currently being displayed or not.

This enhancement would provide valuable information about the fast scroll's visibility status and enable developers to make more informed decisions when designing their application's user experience.

Thank you for considering this feature request, and I appreciate your work on this library.

Random change position when taking your finger out of fastscroll thumb

Expected Behavior

You finish fastscrolling, take your hand out of fastscroller, recyclerview's position stays still.

Actual Behavior

You finish fastscrolling, take your hand out of fastscroller, recyclerview's position jumps up or down. It maybe no problem when you have only 100-200 elements but when you have 50k-100k you may end 100-200 elements up or down from the original position that you had before taking your hand from fastscroller.

Steps to Reproduce the Problem

Fast scroll having your finger on fastscroll thumb.
Take your finger from thumb.
90% of times recyclerview will jump.

In Recyclerview with large data set, button will not go to bottom of list

I can provide any info or samples you need.

This is pretty easy to reproduce:

Create a vertical recyclerview with a lot of items (1 page in my project has 3447 items), try fast scrolling to the bottom.

In current data set, thumb will not go lower than position 3433.

Recyclerview item height is set to ?listPreferredItemHeightSmall

Please let me know if need any other info

PopupTextProvider in FastScrollNestedScrollView

I would like to know how I can implement PopupTextProvider in FastScrollNestedScrollView? The direct child of FastScrollNestedScrollView is a LinearLayout, which contains some TextViews and also a nested RecyclerView (with android:isScrollContainer="false"). I tried to use

new FastScrollerBuilder(mNestedScrollView).setPopupTextProvider(position -> "some text").build();

But the code "some text" is never called. Any ideas?

Incompatible with androidx.recyclerview.selection

Expected Behavior

When AndroidFastScroll is applied to a RecyclerView that has a SelectionTracker set, using the fast scroller should not lead to rows being selected.

Actual Behavior

Scrolling randomly selects rows in the RecyclerView.

Steps to Reproduce the Problem

recyclerView.setSelectionTracker(...)
FastScrollerBuilder(recyclerView).build()
Scroll through the RecyclerView with the fast scroller.

android:tint in GradientDrawable

Hi,

I just found your commit 91a796a to fix the android:tint issues at API level 21. But it seems that you did not workaround for afs_thumb_stateful in RecyclerViewListStatefulFragment.java by changing the method call, which can still induce the issue.

和 BottomNavigationView 一起用会显示异常

只要引入库，即使不使用也会导致 BottomNavigationView 显示不正常。

Add a RecyclerView ViewHelper for dynamic item height

It will be jumping between items when fast scrolling though.

Publish artifacts to Maven Central

JFrog has made the decision to shut down Bintray on May 1st 2021 which means libraries that are only available on JCenter will stop resolving for users. It'd be greatly appreciated if this library is also published to the Sonatype OSS repository so that projects can continue depending on it after JCenter is gone.

ViewHelper with multi item type (多布局的ViewHelper里面如何计算)

Provide an alternate way to set PopupTextProvider

I'm using the latest version of the AndroidFastScroll in conjunction with the FastAdapter library.

Since I cannot customize the implementation of my adapter class, I would like to have an alternate way of providing a standalone PopupTextProvider.

How about providing it as an argument to FastScrollerBuilder ? I can suggest a PR if you want...

Everything works without these lines:

FastScrollerBuilder(fastScrollRecyclerViewNotes)
    .useMd2Style()
    .build()

In my adapter I override PopupTextProvider but my application fails and I can’t understand what the problem is.. Your library example didn't help me.

Don't show scroll handle on first start [hacky solution]

I want to create a behavior where the fast scroll handle isn't shown on app start but when first scrolling. The goal is to have a cleaner and minimalistic look. Normal hide animation should be uneffected.

Without changing the library itself I came up with the hacky workaround at the bottom. Maybe this can be helpful for someone, so I want to share it with you.

Is this maybe a valid feature request implementing this directly into the library? (Used version here: 1.1.4)

/**
 * Hides the fast scroll handle on init, so it's first visible after scrolling.
 */
class HideOnInitAnimationHelper(view: View) : DefaultAnimationHelper(view) {
    private var firstRun = true

    override fun getScrollbarAutoHideDelayMillis(): Int {
        return if (firstRun) {
            0
        } else {
            super.getScrollbarAutoHideDelayMillis()
        }
    }

    override fun showScrollbar(trackView: View, thumbView: View) {
        // Assumption: showScrollbar() is only called once during initialization
        if (firstRun) {
            firstRun = false
            return
        }

        super.showScrollbar(trackView, thumbView)
    }

    override fun hideScrollbar(trackView: View, thumbView: View) {
        if (firstRun) {
            trackView.alpha = 0f
            thumbView.alpha = 0f
        }

        super.hideScrollbar(trackView, thumbView)
    }

FixItemDecorationRecyclerView

any sample on using FixItemDecorationRecyclerView for multiple decorators?
how we can draw it over other decorations with this method .. i mean to clarify it more how to bring fast scroller on top of every other view in the recycler view?
i will appreciate any help thanks ...

Bug: position of the thumb can jump when scrolling

I tried to use this library on my app, and while on some places it seems to work fine, on others it has at least one of these issues:

Scrolling can cause the thumb to jump too much away from current location, sometimes in reverse.
Even dragging the thumb can move it away from the touch location.
Here I will present both using a POC, even though I have no idea if they are exactly the same as on my app.

Expected Behavior

That scrolling will move the thumb in the same direction of scrolling, without big jumps.
And, that moving the thumb by dragging it will follow your touch.

Actual Behavior

The opposite.

Steps to Reproduce the Problem

Import the attached sample, and try both: scroll up and down slowly. And then also drag the thumb up and down slowly.

At first I thought it's because of some clipping attributes or padding, but then I noticed it can occur in other cases too.
So no idea what really causes it.

Smarter position provided by getPopupText(position)

Actual Behavior

I implemented in my app a fullscreen RecyclerView with getPopupText support. It looks like this:

The problem is, the position provided by getPopupText is the first visible item in the Adapter. Though as you can see here, this item (framed in red) is actually barely visible. So while the user only sees items starting with "L", the popup still shows "K", because the very last "K" item still hasn't been recycled.

I was thinking maybe there is a smarter way than getFirstItemAdapterPosition() to get this position.
As I'm a bit curious, I investigated how other fast scrollers handle this issue. For instance, Nova Launcher's widget list uses a fast scroll which applies some kind of padding to this position, proportional to how low you are in the list (the more you scroll, the lower the item targeted by getPopupText is on the screen). Which enables their popup to use the very first item's position when you're at the top, the very last item's position when you're at the bottom, and the position of an item which is always visible when you're anywhere in between.

It's kinda hard to explain with words. Actually experimenting with it helps to understand.
I am also aware that the Google Contacts app works in a similar way (using the first visible item), though it's not a problem because their list is not full screen, and the list snaps when fast scrolling, to make sure the first item is always fully visible. Not all lists can mimic this behavior though.

Expected Behavior

The position provided by getPopupText should target an item which is always (clearly) visible to the user.

Steps to Reproduce the Problem

Create a RecyclerView and simply bind a FastScroller with FastScrollerBuilder(recyclerView).build() (the issue is more visible with a full screen RV).
Implement PopupTextProvider in the Adapter.
Scroll.
