onSwipe事件不是ViewPager内触发 [英] onSwipe Event is not Triggered inside a ViewPager
问题描述
的请参见下面的更新的
我有一个 ViewPager ，第一页（片段）它有一个 DrawerLayout 实现了一个 SimpleOnGestureListener 侦听 onSwipe 事件。在 onSwipe 事件 DrawerLayout （片段）的目的是，如果用户扫描到<$ C $听C>左和右键触发的抽屉的开幕式和闭幕式。 
问题是由时间，我刷到向左或向右中的 ViewPager的页面修改的，而不是引发的开幕式和闭幕式的抽屉。
有没有办法为停用的临时刷卡的 ViewPager ，而其目前的观点是对 DrawerLayout ，以便它可以侦听到左和右的事件？
如果抽屉的打开的，如果我轻扫屏幕向右那么这就是时间的页面变化。我一直在这个挣扎了几天了。
我这个可能在 DrawerLayoutFragment ？
如果（MainClass_ViewPager.getView == getActivity（）。getView）

获取演示NavDrawer的这里
如果您在ViewPager实施样品code给出的星球选择帧交换，它会正常工作。
详细内容：
在选择信息只是在'片段'对象，它是FragmentManager交易的目标得到ViewPager。这将做到这一点，你将有NavDrawer与ViewPager一起。不要禁用任何东西，因为它只是工作。
请参阅下面的planetfragement' - 只要将你的ViewPager类，它会所有的工作。取出planetfragment。添加您的ViewPager在它的地方。这是所有的u必须做的。你'viewpager'应该是一个片段，获取一个ViewPager和钩它到一个适配器。它实现了相同的接口，目前样品中的行星。只要将它

Please see update below
I have a ViewPager, the first page(fragment) of it has a DrawerLayout that implements a SimpleOnGestureListener that listens to onSwipe event. The purpose of the onSwipe event inside the DrawerLayout(fragment) is to listen if the user swipes to left and right which triggers the opening and closing of the drawer.
The problem is by the time, I swipe to left or right the ViewPager's page changes instead of triggering the opening and closing of the Drawer.
Is there a way to disable temporarily the swiping of the ViewPager, while its current view is on DrawerLayout so that it can listen to the left and right event?
If the Drawer is opened and If I swipe the screen to the right then that's the time the page changes. I've been struggling with this for a couple of days now.
I this possible inside the DrawerLayoutFragment?
if(MainClass_ViewPager.getView == getActivity().getView)
MainClass_ViewPager.isEnabled(false)
onSwipe of `DrawerLayoutFragment` is triggered

UPDATE - this is what I got so far. I have a parent ViewPager that has a child ViewPager(fragment), I can't handle the swiping of the child ViewPager because the parent one is always got swiped not giving any chance for the child one. The drawer is working, as along as I hold the left side of the screen for a sec then drag it to the right. As shown in the image above.
private void selectItem(int position) {
Log.d("selectItem", "inside");
// update the main content by replacing fragments
ViewPagerConnect fragment = new ViewPagerConnect();
Bundle args = new Bundle();
args.putInt("position", position);
fragment.setArguments(args);
FragmentTransaction ft = getChildFragmentManager().beginTransaction();
ft.add(R.id.content_frame, fragment);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
setTitle(mPlanetTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}

AppSectionsPagerAdapter mAppSectionsPagerAdapter;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,

mAppSectionsPagerAdapter = new AppSectionsPagerAdapter(getChildFragmentManager());
position = getArguments().getInt("position");
View rootView = inflater.inflate(R.layout.viewpager_connect, container, false);
mViewPager = (ViewPager) rootView.findViewById(R.id.pager);
mViewPager.setAdapter(mAppSectionsPagerAdapter);
return rootView;

Get the demo NavDrawer here
If you swap in a ViewPager implementation for the Planet Selection frame given in the sample code, it will work fine.
Details:
in 'selectItem' just get a ViewPager in the 'fragment' object that is the target of the FragmentManager transaction. That will do it and you will have the NavDrawer along with the ViewPager. Dont disable anything because it will just work.
see the 'planetfragement' below - just swap in your ViewPager class and it will all work. Remove the planetfragment. Add your ViewPager in its place. that is all u have to do. Your 'viewpager' should be a Fragment that gets a ViewPager and hooks it up to an adapter. It implements the same interface as the Planets in the current sample. just swap it in.
private void selectItem(int position) {
// update the main content by replacing fragments
Fragment fragment = new PlanetFragment();
Bundle args = new Bundle();
args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position);
fragment.setArguments(args);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
setTitle(mPlanetTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
