您可以定义一个自定义的滚动滚动类, 并在此滚动时添加一个界面 :

public class ScrollChangeListenerScrollView extends HorizontalScrollView {


private MyScrollListener mMyScrollListener;

public ScrollChangeListenerScrollView(Context context) {
    super(context);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}


public void setOnMyScrollListener(MyScrollListener myScrollListener){
    this.mMyScrollListener = myScrollListener;
}


@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
    super.onScrollChanged(l, t, oldl, oldt);
    if(mMyScrollListener!=null){
        mMyScrollListener.onScrollChange(this,l,t,oldl,oldt);
    }

}

public interface MyScrollListener {
    void onScrollChange(View view,int scrollX,int scrollY,int oldScrollX, int oldScrollY);
}

}

    // --------Start Scroll Bar Slide--------
    final HorizontalScrollView xHorizontalScrollViewHeader = (HorizontalScrollView) findViewById(R.id.HorizontalScrollViewHeader);
    final HorizontalScrollView xHorizontalScrollViewData = (HorizontalScrollView) findViewById(R.id.HorizontalScrollViewData);
    xHorizontalScrollViewData.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
        @Override
        public void onScrollChanged() {
            int scrollX; int scrollY;
            scrollX=xHorizontalScrollViewData.getScrollX();
            scrollY=xHorizontalScrollViewData.getScrollY();
            xHorizontalScrollViewHeader.scrollTo(scrollX, scrollY);
        }
    });
    // ---------End Scroll Bar Slide---------

Kotlin 用户在寻找普通 < code> scrollView 执行的解决方案 :

作为的延伸至><这个答案 ,我创建了一种能够很好地解决我问题的定制观点。

视图( 创建一个新的 Kotlin 文件, 将您的软件包引用维持在第1行) :

import android.annotation.SuppressLint
import android.content.Context
import android.util.AttributeSet
import android.view.MotionEvent
import android.widget.ScrollView
import kotlin.math.abs


class ScrollViewWithEndFunc (
    context: Context?,
    attrs: AttributeSet?,
    defStyle: Int
) : ScrollView(context, attrs, defStyle) {

    constructor(context: Context?) : this(context, null, 0) {}
    constructor(context: Context?, attrs: AttributeSet?) : this(context, attrs, 0) {}

    interface OnScrollListener {
        fun onScrollChanged(scrollView: ScrollViewWithEndFunc?, x: Int, y: Int, oldX: Int, oldY: Int)
        fun onEndScroll(scrollView: ScrollViewWithEndFunc?)
    }

    private var isScrolling = false
    private var isTouching = false
    private var scrollingRunnable: Runnable? = null
    private var onScrollListener: OnScrollListener? = null

    fun setOnScrollListener(onScrollListener: OnScrollListener) {
        this.onScrollListener = onScrollListener
    }

    fun removeOnScrollListener() {
        this.onScrollListener = null
    }

    @SuppressLint("ClickableViewAccessibility")
    override fun onTouchEvent(ev: MotionEvent): Boolean {
        val action = ev.action
        if (action == MotionEvent.ACTION_MOVE) {
            isTouching = true; isScrolling = true
        } else if (action == MotionEvent.ACTION_UP || action == MotionEvent.ACTION_CANCEL) {
            if (isTouching && !isScrolling) {
                onScrollListener?.onEndScroll(this)
            }
            isTouching = false
        }
        return super.onTouchEvent(ev)
    }

    override fun onScrollChanged(x: Int, y: Int, oldX: Int, oldY: Int) {
        super.onScrollChanged(x, y, oldX, oldY)
        if (abs(oldY - y) > 0) {
            scrollingRunnable?.let { removeCallbacks(it) }
            scrollingRunnable = Runnable {
                if (isScrolling && !isTouching) {
                    onScrollListener?.onEndScroll(this@ScrollViewWithEndFunc)
                }
                isScrolling = false
                scrollingRunnable = null
            }
            postDelayed(scrollingRunnable, 200)
        }
        onScrollListener?.onScrollChanged(this, x, y, oldX, oldY)
     }
    }

XML 视图执行 :

<your.package.here.ScrollViewWithEndFunc
        android:id="@+id/scrollview_main_dashboard"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true">

活动/分散执行:

scrollviewMainDashboard.setOnScrollListener(object : ScrollViewWithEndFunc.OnScrollListener {
            override fun onScrollChanged(scrollView: ScrollViewWithEndFunc?, x: Int, y: Int, oldX: Int, oldY: Int) { }
            override fun onEndScroll(scrollView: ScrollViewWithEndFunc?) {
                /* Scroll ended, handle here */
        })
