Sliding Collision of Android slide menu and Carousel diagram

To take over a project, there is a problem that needs to be modified: The carousel diagram cannot be manually slid, and manual sliding of the carousel will only trigger a slide-off menu.

Guess: The touch events of the Viewpager Control (Carousel map) were intercepted by the Slidingmenu control (slide-off menu, non-third-party project, which was the last developer-defined).

Based on this speculation, I customize a viewpager, rewrite the dispatchtouchevent, onintercepttouchevent, and Ontouchevent, respectively, in these three methods to print a log;

Rewrite Slidingmenu's dispatchtouchevent, Onintercepttouchevent, and ontouchevent, and print log as well.

Recompile run, hand pulley plot, log as follows:

As can be seen from log, it is also possible to pass a sliding event to Viewpager, which is then intercepted by Slidingmenu. This log confirms that the conjecture is correct.

Know the reason to solve, I now have to consider is: to achieve what effect.

Expected effect: You can slide the carousel normally, and when the carousel is on the first slide, slide to the side-slip menu.

Someone on the internet has shared a similar problem. I have borrowed a bit of it here.

The first function is to realize that the carousel diagram can be slid normally.

You can set a global variable: public static Boolean mrollviewpagertouching;

Used to indicate whether the carousel is in touch.

In the custom Viewpager, decide whether to touch the carousel diagram

 Public Booleandispatchtouchevent (motionevent ev) {Switch(Ev.getaction ()) { CaseMotionevent.action_move: Break;  CaseMotionEvent.ACTION_DOWN:MyApplication.mRollViewPagerTouching=true;  Break;  CaseMotionEvent.ACTION_UP:MyApplication.mRollViewPagerTouching=false;  Break; }        return Super. dispatchtouchevent (EV); }

In Slidingmenu, make the following treatment

 Public Boolean onintercepttouchevent (motionevent ev) {        if  (myapplication.mrollviewpagertouching) {             returnfalse;        }         return Super . onintercepttouchevent (EV);    }

Recompile runs, you can slide the carousel normally, but when the carousel is on the first one, you cannot slide to the side-slip menu.

Now for the second function: When the carousel is on the first slide, you can slide to the side-slip menu.

Here are two places to note: 1. When the carousel is on the first, 2. Since my slide-in menu is on the left, I need the finger to slide right into the side-slip menu, so the second condition should be the right slide.

Based on the above, modify the custom Viewpager code

 Public Booleandispatchtouchevent (motionevent ev) {//go back to the starting coordinates when triggered        floatx =Ev.getx (); Switch(Ev.getaction ()) { CaseMotionevent.action_move://get to distance difference                floatDX = x-Downx; //prevention is also judged by the press                if(Math.Abs (DX) > 8) {                    //Judging direction by distance difference                    if(DX > 0) {                        //"right";                        if(Getcurrentitem () = = 0) {myapplication.mrollviewpagertouching=false; } Else{myapplication.mrollviewpagertouching=true; }                    } Else {                        //"left";Myapplication.mrollviewpagertouching =true; }                }                 Break;  CaseMotionevent.action_down://Store the coordinates when pressedDownx =x; Myapplication.mrollviewpagertouching=true;  Break;  CaseMotionEvent.ACTION_UP:MyApplication.mRollViewPagerTouching=false;  Break; }        return Super. dispatchtouchevent (EV); }

Compile and run again to achieve the desired results.

PS: simple function, simple sharing.
