ScrollView bounces back on some android devices, when ScrollVIew set horizontal is true。

Description

Vertical scrolling, Android has made special adjustments to the P version, but horizontal scrolling has not been addressed, resulting in rebound issues when horizontal scrolling is too fast. The following is the processing code for vertical scrolling and the code for not processing the Android P version during horizontal scrolling.

vertical scrollview

@Override
  public void fling(int velocityY) {
    final int correctedVelocityY = correctFlingVelocityY(velocityY);

    if (mPagingEnabled) {
      flingAndSnap(correctedVelocityY);
    } else if (mScroller != null) {
      // FB SCROLLVIEW CHANGE

      // We provide our own version of fling that uses a different call to the standard OverScroller
      // which takes into account the possibility of adding new content while the ScrollView is
      // animating. Because we give essentially no max Y for the fling, the fling will continue as
      // long
      // as there is content. See #onOverScrolled() to see the second part of this change which
      // properly
      // aborts the scroller animation when we get to the bottom of the ScrollView content.

      int scrollWindowHeight = getHeight() - getPaddingBottom() - getPaddingTop();

      mScroller.fling(
          getScrollX(), // startX
          getScrollY(), // startY
          0, // velocityX
          correctedVelocityY, // velocityY
          0, // minX
          0, // maxX
          0, // minY
          Integer.MAX_VALUE, // maxY
          0, // overX
          scrollWindowHeight / 2 // overY
          );

      ViewCompat.postInvalidateOnAnimation(this);

      // END FB SCROLLVIEW CHANGE
    } else {
      super.fling(correctedVelocityY);
    }
    handlePostTouchScrolling(0, correctedVelocityY);
  }

  private int correctFlingVelocityY(int velocityY) {
    if (Build.VERSION.SDK_INT != Build.VERSION_CODES.P) {
      return velocityY;
    }

    // Workaround.
    // On Android P if a ScrollView is inverted, we will get a wrong sign for
    // velocityY (see https://issuetracker.google.com/issues/112385925).
    // At the same time, mOnScrollDispatchHelper tracks the correct velocity direction.
    //
    // Hence, we can use the absolute value from whatever the OS gives
    // us and use the sign of what mOnScrollDispatchHelper has tracked.
    float signum = Math.signum(mOnScrollDispatchHelper.getYFlingVelocity());
    if (signum == 0) {
      signum = Math.signum(velocityY);
    }
    return (int) (Math.abs(velocityY) * signum);
  } 

horizontal scrollview

  @Override
  public void fling(int velocityX) {
    if (DEBUG_MODE) {
      FLog.i(TAG, "fling[%d] velocityX %d", getId(), velocityX);
    }

    // Workaround.
    // On Android P if a ScrollView is inverted, we will get a wrong sign for
    // velocityX (see https://issuetracker.google.com/issues/112385925).
    // At the same time, mOnScrollDispatchHelper tracks the correct velocity direction.
    //
    // Hence, we can use the absolute value from whatever the OS gives
    // us and use the sign of what mOnScrollDispatchHelper has tracked.
    final int correctedVelocityX =
        (int) (Math.abs(velocityX) * Math.signum(mOnScrollDispatchHelper.getXFlingVelocity()));

    if (mPagingEnabled) {
      flingAndSnap(correctedVelocityX);
    } else if (mScroller != null) {
      // FB SCROLLVIEW CHANGE

      // We provide our own version of fling that uses a different call to the standard OverScroller
      // which takes into account the possibility of adding new content while the ScrollView is
      // animating. Because we give essentially no max X for the fling, the fling will continue as
      // long
      // as there is content. See #onOverScrolled() to see the second part of this change which
      // properly
      // aborts the scroller animation when we get to the bottom of the ScrollView content.

      int scrollWindowWidth =
          getWidth() - ViewCompat.getPaddingStart(this) - ViewCompat.getPaddingEnd(this);

      mScroller.fling(
          getScrollX(), // startX
          getScrollY(), // startY
          correctedVelocityX, // velocityX
          0, // velocityY
          0, // minX
          Integer.MAX_VALUE, // maxX
          0, // minY
          0, // maxY
          scrollWindowWidth / 2, // overX
          0 // overY
          );

      ViewCompat.postInvalidateOnAnimation(this);

      // END FB SCROLLVIEW CHANGE
    } else {
      super.fling(correctedVelocityX);
    }
    handlePostTouchScrolling(correctedVelocityX, 0);
  }

Steps to reproduce

Set scrollview to horizontal scrolling, then fill in sub elements to allow scrollview to scroll horizontally, and then continuously slide towards the bottom when scrollview scrolls to the bottom, causing scrollview to experience rebound issues.

Rà soát đường đi của Android horizontal ScrollView fling(int velocityX) được nêu trong issue, đối chiếu với triển khai vertical fling và Android P workaround. Tái hiện thao tác vuốt ngang nhanh ở cuối nội dung có thể cuộn trên một thiết bị Android bị ảnh hưởng; hoàn tất nghĩa là ScrollView không còn bật ngược trong khi hành vi horizontal fling bình thường vẫn được giữ nguyên.
