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。

using System.Linq;

    // Need to disable swiping for ViewPager, if user performs Pre DSA and the dsa is not completed yet
    // http://stackoverflow.com/questions/9650265/how-do-disable-paging-by-swiping-with-finger-in-viewpager-but-still-be-able-to-s
    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>

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);

            }
             ...
           }

尝试从onInterceptTouchEvent()和/或onTouchEvent()中覆盖并返回true，这将使用分页器上的触摸事件。

shareViewPager?.setOnTouchListener(object :View.OnTouchListener{
            override fun onTouch(v: View?, event: MotionEvent?): Boolean {
                for (PAGE in 0..shareViewPager.adapter!!.count){
                    if (shareViewPager.currentItem==PAGE){
                        shareViewPager.setCurrentItem(PAGE-1,false)
                        shareViewPager.setCurrentItem(PAGE,false)
                    }}
                return true
            }

        })

你需要子类化ViewPager。onTouchEvent有很多你不想改变的东西比如允许子视图获得触摸。onInterceptTouchEvent是你想要改变的。如果你查看ViewPager的代码，你会看到这样的注释:

    /*
     * This method JUST determines whether we want to intercept the motion.
     * If we return true, onMotionEvent will be called and we do the actual
     * scrolling there.
     */

这里有一个完整的解决方案:

首先，将这个类添加到src文件夹中:

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.animation.DecelerateInterpolator;
import android.widget.Scroller;
import java.lang.reflect.Field;

public class NonSwipeableViewPager extends ViewPager {

    public NonSwipeableViewPager(Context context) {
        super(context);
        setMyScroller();
    }

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

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        // Never allow swiping to switch between pages
        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // Never allow swiping to switch between pages
        return false;
    }

    //down one is added for smooth scrolling

    private void setMyScroller() {
        try {
            Class<?> viewpager = ViewPager.class;
            Field scroller = viewpager.getDeclaredField("mScroller");
            scroller.setAccessible(true);
            scroller.set(this, new MyScroller(getContext()));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public class MyScroller extends Scroller {
        public MyScroller(Context context) {
            super(context, new DecelerateInterpolator());
        }

        @Override
        public void startScroll(int startX, int startY, int dx, int dy, int duration) {
            super.startScroll(startX, startY, dx, dy, 350 /*1 secs*/);
        }
    }
}

接下来，确保使用这个类而不是常规的ViewPager，你可能指定为android.support.v4.view.ViewPager。在你的布局文件中，你会想要像这样指定它:

<com.yourcompany.NonSwipeableViewPager
    android:id="@+id/view_pager"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />

这个特殊的例子是在线性布局中，意味着占据整个屏幕，这就是为什么layout_weight是1,layout_height是0dp。

和setMyScroller ();方法是为了平稳过渡

如果你使用的是ViewPager2，你只需要使用:

viewpager.setUserInputEnabled(假);

从文档中可以看出:

启用或禁用用户主动滚动。这包括触摸输入(滚动和投掷手势)和可访问性输入。目前还不支持禁用键盘输入。当用户发起的滚动被禁用时，通过setCurrentItem进行的编程滚动仍然有效。默认情况下，用户主动滚动是启用的。
