当Listview位于顶部/底部时,将运动事件传递给父Scrollview

您可以创建自定义 ScrollView 和 ListView 和覆盖

onInterceptTouchEvent(MotionEvent event)

这样地:

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    View view = (View) getChildAt(getChildCount()-1);
    int diff = (view.getBottom()-(getHeight()+getScrollY()));

    if( event.getAction() == MotionEvent.ACTION_DOWN) {
        if (diff ==0) {
            return false;
        }
    }

    return super.onInterceptTouchEvent(event);
}

这样每次向下触摸 列表视图 当你在 卷轴视图 将前往 列表视图 .

这只是一个草图实现,但我认为您可以通过执行相同的操作来检测何时处于 列表视图

需要注意的是,我只需要使用 列表视图 以您当前的内容 卷轴视图 通过使用添加为ListView的标头 listView.addHeaderView(scrollViewContent) 我不知道这是否符合你的需要。

编辑:

检测何时开始滚动 卷轴视图 .保留以下内容的参考 列表视图 在 卷轴视图 。当用户向上滚动时 列表视图 位于顶部,让事件由 卷轴视图 .

private void init(){
    ViewConfiguration vc = ViewConfiguration.get(getContext());
    mTouchSlop = vc.getScaledTouchSlop();
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    final int action = MotionEventCompat.getActionMasked(event);

    switch (action) {
        case MotionEvent.ACTION_DOWN:{
            yPrec = event.getY();
        }
        case MotionEvent.ACTION_MOVE: {
            final float dy = event.getY() - yPrec;

            if (dy > mTouchSlop) {
                // Start scrolling!
                mIsScrolling = true;
            }
            break;
        }
    }

    if (action == MotionEvent.ACTION_CANCEL || action == MotionEvent.ACTION_UP) {
        mIsScrolling = false;
    }

    // Calculate the scrolldiff
    View view = (View) getChildAt(getChildCount()-1);
    int diff = (view.getBottom()-(getHeight()+getScrollY()));

        if ((!mIsScrolling || !listViewReference.listIsAtTop()) && diff == 0) {
            if (event.getAction() == MotionEvent.ACTION_MOVE) {
                return false;
            }
    }

    return super.onInterceptTouchEvent(event);
}

@Override
public boolean onTouchEvent(MotionEvent ev) {
    final int action = MotionEventCompat.getActionMasked(ev);
    if (action == MotionEvent.ACTION_CANCEL || action == MotionEvent.ACTION_UP) {
        mIsScrolling = false;
    }
    return super.onTouchEvent(ev);
}


public void setListViewReference(MyListView listViewReference) {
    this.listViewReference = listViewReference;
}

ListView中的listIsAtTop方法如下所示:

public boolean listIsAtTop()   {
    if(getChildCount() == 0) return true;
    return (getChildAt(0).getTop() == 0 && getFirstVisiblePosition() ==0);
}

您不应该将ListView放在ScrollView中,但可以使用 ExpandableHeightListView 。这将在ScrollView中生成全高Listview。无需添加TouchListener。

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >
             <!-- your content -->
        </RelativeLayout>

        <my.widget.ExpandableHeightListView
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>
</ScrollView>

另一种实现您需求的方法是 RecyclerView 带收割台。

试试看:

1. 首先找到是否到达滚动视图底部。将onScrollChanged注册到Scroll视图

   @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
       if( diff == 0 )
       {
           // notify that we have reached the bottom
           // Add code here to start scrolling the ListView
           Log.d(ScrollTest.LOG_TAG, "MyScrollView: Bottom has been reached" );
       }
   
       super.onScrollChanged(l, t, oldl, oldt);
   }
   

2. 检查是否到达ListView的顶部。检查firstVisibleItem是否为0:-

   tableListView.setOnScrollListener(new OnScrollListener() {
   
           public void onScrollStateChanged(AbsListView view, int scrollState) {
   
           }
   
           public void onScroll(AbsListView view, int firstVisibleItem,
                   int visibleItemCount, int totalItemCount) {
               if (visibleItemCount == 0)
               // you have reached at top of lustView
               {
                   java.lang.System.out.println("you have reached at top of lustView!");
               }
               else {
                   if ((firstVisibleItem + visibleItemCount) == totalItemCount) {
                       // put your stuff here
                       java.lang.System.out.println("end of the line reached!");
                   }
               }
   
           }
       });
   

我希望这对你有用。如果遇到任何问题,请告诉我。
