When using Viewpager, how to resolve and sub-page long press the sliding conflict problem.

My problem prototype:

This problem, I believe meet people will be less, I was in a viewpager, one of the fragment realized the long press the function of sliding pictures, and found them both

Ontouchevent event conflict.

The solution that has been tried:


Encounter this problem, the first is Baidu, Baidu to the method has, custom Viewpager, in the inside rewrite ontouchevent and onintercepttouchevent, the specific code is below, this method, I try

found that only in the first load Viewpager page to achieve the blocking effect, I here in detail, in the Mainactivity page, we initialized the Viewpager, and then we will be on the second page of the

Fragment in the block, you might try to fragment a Mainactivity object in the new, and then somehow get the viewpager inside it, or introduce it with Mainactiv ity

Bind the XML file, and then Findviewbyid () in fragment to get the secondary viewpager. then use the function inside the custom Viewpager.

Unfortunately, the way I talked about it, I tried, all failed.

Ontouchevent (event); to         } +         return false; -     } the  *  $ @OverridePanax Notoginseng      Public Booleanonintercepttouchevent (Motionevent event) { -         if( This.

The second way is that I finally really solved it. In the beginning, the use of errors, resulting in failure.

Method: View.requestdisallowintercepttouchevent (True); The incoming parameter is true

The reason I failed to use it for the first time was:

In my fragment, because Viewpager it is a view, so when I use this method, it is directly

Viewpager. Requestdisallowintercepttouchevent (True);  The result is a failure. the correct way to use the child view is below ↓


View.requestdisallowintercepttouchevent (True), the view requirement used in is the view returned by the XML you are currently fragment introduced, and instead:

View. getParent (). Requestdisallowintercepttouchevent (TRUE);

At this point can really solve! Some of the necessary code is introduced below.

1 View main = inflater.inflate (R.layout.apart_center,container,false);
1 main.getparent (). Requestdisallowintercepttouchevent (true);
