解决方案

  

我将如何着手确保滑动手势的ListView控件被捕获消耗它们传递给ViewPager过吗？

创建 ViewPager 的子类，并覆盖 canScroll（）。如果提供的查看是的ListView ，返回真来已经触摸事件给予了的ListView 。

例如，这里是一类我一些样品中使用的主办地图一个 ViewPager ：

现在，这是完全可能的，可能会有更多，让你的刷卡到解雇劳动 ViewPager 里面，但我会从这里开始。

I have a ListView that captures swipe gestures to delete a row. This ListView lives in a Fragment. On phones this is in it's own Activity and works great. On tablets this Fragment is in a ViewPager and the ListView is never able to capture any of the the swipe events since they always go to the ViewPager.

How would I go about making sure swipe gestures are captured by the ListView to consume before they are passed to the ViewPager?

P.S. I am using this library for my swipe to dismiss gestures in my ListView

解决方案

How would I go about making sure swipe gestures are captured by the ListView to consume before they are passed to the ViewPager?

Create a subclass of ViewPager and override canScroll(). If the supplied View is the ListView, return true to have the touch events be given to the ListView.

For example, here is a class I use in some samples for hosting maps in a ViewPager:

package com.commonsware.android.mapsv2.pager;

import android.content.Context;
import android.support.v4.view.PagerTabStrip;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.SurfaceView;
import android.view.View;

public class MapAwarePager extends ViewPager {
  public MapAwarePager(Context context, AttributeSet attrs) {
    super(context, attrs);
  }

  @Override
  protected boolean canScroll(View v, boolean checkV, int dx, int x,
                              int y) {
    if (v instanceof SurfaceView || v instanceof PagerTabStrip) {
      return(true);
    }

    return(super.canScroll(v, checkV, dx, x, y));
  }
}

Now, it is entirely possible that there may be more to getting your swipe-to-dismiss to work inside the ViewPager, but I would start here.
