Android禁用可交换的视图Pager

Question

我正在尝试禁用和启用查看pager可交换程序，但是在下面的代码上，多次滑动在查看pager上，禁用/启用功能不起作用

public static void changeSwappableViewPagerStatus(ViewPagerCustomDuration viewPager, boolean status) {
    if (status) {
        viewPager.setOnTouchListener(null);
    } else {
        viewPager.setOnTouchListener(new View.OnTouchListener() {
            public boolean onTouch(View arg0, MotionEvent arg1) {
                return true;
            }
        });
    }
}

要执行此操作，您应该像以下那样制作一个视图子类，并在OnTouchEvent中进行：

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*/);
    }
}
}
