现在我们不需要创建自定义ViewPager

android中有一个新的ViewPager2名称View

垂直方向支撑

除了传统的水平分页之外，ViewPager2还支持垂直分页。你可以通过设置ViewPager2元素的android:orientation属性来启用垂直分页

使用XML

<androidx.viewpager2.widget.ViewPager2
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/pager"
    android:orientation="vertical" />

使用代码

在viewpager2中禁用滑动

viewPager2.setUserInputEnabled(false);

在viewpager2使用中启用滑动

viewPager2.setUserInputEnabled(true);

如果你想在Xamarin中为Android实现同样的功能，这里有一个c#的翻译

我选择将属性命名为“ScrollEnabled”。因为iOS使用的是完全相同的命名。因此，在两个平台上都有相同的命名，这使开发人员更容易。

    // Need to disable swiping for ViewPager, if user performs Pre DSA and the dsa is not completed yet

    public class CustomViewPager: ViewPager {
        public bool ScrollEnabled;

        public CustomViewPager(Context context, IAttributeSet attrs) : base(context, attrs) {
            this.ScrollEnabled = true;
        }

        public override bool OnTouchEvent(MotionEvent e) {
            if (this.ScrollEnabled) {
                return base.OnTouchEvent(e);
            }
            return false;
        }

        public override bool OnInterceptTouchEvent(MotionEvent e) {
            if (this.ScrollEnabled) {
                return base.OnInterceptTouchEvent(e);
            }
            return false;
        }

        // For ViewPager inside another ViewPager
        public override bool CanScrollHorizontally(int direction) {
            return this.ScrollEnabled && base.CanScrollHorizontally(direction);
        }

        // Some devices like the Galaxy Tab 4 10' show swipe buttons where most devices never show them
        // So, you could still swipe through the ViewPager with your keyboard keys
        public override bool ExecuteKeyEvent(KeyEvent evt) {
            return this.ScrollEnabled ? base.ExecuteKeyEvent(evt) : false;
        }
    }
}

在.axml文件:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
  <YourNameSpace.ViewPackage.CustomViewPager
      android:id="@+id/pager"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:background="@android:color/white"
      android:layout_alignParentTop="true" />
</LinearLayout>

禁用滑动

mViewPager.beginFakeDrag();

启用滑动

mViewPager.endFakeDrag();

这是我的实现 如果你想禁用滑动动画，你可以左右使用swipeListener，仍然希望通过手指滚动，但没有动画

1-覆盖Viewpager方法onInterceptTouchEvent和onTouchEvent

2-创建自己的手势检测器

3-检测滑动手势并使用setCurrentItem(item, false)

ViewPager

public class ViewPagerNoSwipe extends ViewPager {
    private final GestureDetector gestureDetector;
    private OnSwipeListener mOnSwipeListener;

    public void setOnSwipeListener(OnSwipeListener onSwipeListener) {
        mOnSwipeListener = onSwipeListener;
    }

    public ViewPagerNoSwipe(@NonNull Context context) {
        super(context);
        gestureDetector = new GestureDetector(context, new GestureListener());

    }

    public ViewPagerNoSwipe(@NonNull Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
        gestureDetector = new GestureDetector(context, new GestureListener());


    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        return true;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        gestureDetector.onTouchEvent(ev);
        return false;
    }

    public class GestureListener extends GestureDetector.SimpleOnGestureListener {

        private static final int SWIPE_THRESHOLD = 100;
        private static final int SWIPE_VELOCITY_THRESHOLD = 100;

        @Override
        public boolean onDown(MotionEvent e) {
            return true;
        }

        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            boolean result = false;
            try {
                float diffY = e2.getY() - e1.getY();
                float diffX = e2.getX() - e1.getX();
                if (Math.abs(diffX) > Math.abs(diffY)) {
                    if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                        if (diffX > 0) {
                            if(mOnSwipeListener!=null)
                            mOnSwipeListener.onSwipeRight();
                        } else {
                            if(mOnSwipeListener!=null)
                                mOnSwipeListener.onSwipeLeft();
                        }
                        result = true;
                    }
                } else if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffY > 0) {
                        if(mOnSwipeListener!=null)
                            mOnSwipeListener.onSwipeBottom();
                    } else {
                        if(mOnSwipeListener!=null)
                            mOnSwipeListener.onSwipeTop();
                    }
                    result = true;
                }
            } catch (Exception exception) {
                exception.printStackTrace();
            }
            return result;
        }
    }

    public interface OnSwipeListener {

         void onSwipeRight();

        void onSwipeLeft();

        void onSwipeTop();

        void onSwipeBottom();
    }
}

当你设置ViewPager时，设置swipeListener

postsPager.setOnSwipeListener(new ViewPagerNoSwipe.OnSwipeListener() {
            @Override
            public void onSwipeRight() {

              postsPager.setCurrentItem(postsPager.getCurrentItem() + 1,false);

            }

            @Override
            public void onSwipeLeft() {

            postsPager.setCurrentItem(postsPager.getCurrentItem() - 1, false);

            }
             ...
           }

最简单的方法是setOnTouchListener并为ViewPager返回true。

mPager.setOnTouchListener(new OnTouchListener()
    {           
        @Override
        public boolean onTouch(View v, MotionEvent event)
        {
            return true;
        }
    });

在Kotlin，我的解决方案，结合上述答案。

class CustomViewPager(context: Context, attrs: AttributeSet): ViewPager(context, attrs) {
    var swipeEnabled = false

    override fun onTouchEvent(ev: MotionEvent?): Boolean {
        return if (swipeEnabled) super.onTouchEvent(ev) else false
    }

    override fun onInterceptTouchEvent(ev: MotionEvent?): Boolean {
        return if (swipeEnabled) super.onInterceptTouchEvent(ev) else false
    }

    override fun executeKeyEvent(event: KeyEvent): Boolean {
        return if (swipeEnabled) super.executeKeyEvent(event) else false
    }
}
